Editor's note

AH, WINTER – FROSTY MORNINGS, DARK evenings and dodging viruses here, there and everywhere. Yet winter is also a time for evenings by the fire, cosy sweaters and hot drinks – all of which can be enjoyed while reading our July issue.

One of the most serious challenges facing the planet is the environment: cleaning up the existing pollution as best as possible and leaving behind a habitable world for future generations. In this issue, De Beers shares an update on progress toward its 2030 “Building Forever” sustainability goals. The goals were set in 2020 and are De Beers’ blueprint for creating a positive and sustainable impact in its host countries and throughout the diamond value chain. The Gemological Institute of America (GIA) has also released its first sustainability report and strategy, which was developed in reference to the Global Reporting Initiative framework. It includes baseline achievements for 2022 on a range of social, environmental and governance programmes, as well as the GIA’s 2025 sustainability strategy, “Championing Transparency”.

JCK Las Vegas, held from 2-5 June, has once again confirmed its status as

a global hub for the jewellery industry. SAJN international correspondent Smitha Sadanandan asked some of the renowned international brands which launched new bridal collections at this year’s show what has been trending.

Mike Freislich, a respected coach, trainer and the co-founder of We Do Change, also shares the top six organisational changes that defined the past two years and how they impact a team’s ability to become agile, modify and move forward.

As a player in our industry and a member of the Jewellery Council of SA (JCSA), we are extremely grateful for the work CEO Lorna Lloyd and her team do behind the scenes. Accordingly, we are excited to re-introduce her “Message From the CEO” from this issue.

If you are anything like me, then you are probably also struggling to be your usual upbeat self during the cold weather. We hope this issue will help you stay positive when you feel the winter blues creeping in.

Happy reading!

Registration now open for 2023 CIBJO Congress

CIBJO’s 2023 annual congress will take place in Jaipur, in the Indian state of Rajasthan, from 3-5 October. Pre-congress meetings will be held on 1 and 2 October. The hosts of the congress are the Gem & Jewellery Export Promotion Council (GJEPC) and the co-host is the National Gem & Jewellery Council of India (NGJCI). The congress venue will be the Jaipur Exhibition and Congress Centre (JECC).

Upon registering, delegates will also be able to pre-book hotel rooms using links provided on the dedicated website for the official congress hotel, which is located directly above the convention complex at the JECC.

CIBJO Congresses serve as the gathering place for the World Jewellery Confederation’s Assembly of Delegates and are also the venue for the annual meetings of CIBJO’s sectoral commissions, where amendments can be introduced to the organisation’s definitive directories of international industry standards for diamonds, coloured stones, pearls, gem labs, precious metals coral and responsible

sourcing, known as the Blue Books.

The CIBJO Congress is also where there reports are given on the programmes of the World Jewellery Confederation Education Foundation (WJCEF), as well as activities related to CIBJO’s ongoing co-operation with the United Nations and its development programme.

Known as the Pink City because of the characteristic burnt ochre colour of many of the buildings in its centre, Jaipur is both the capital of Rajasthan and also its largest city, with more than 4 million residents. Its connection to the jewellery industry dates back to its establishment in 1727. Skilled craftsmen, including jewellers and stone-cutters, were brought in, creating an enamelling and gem-setting tradition that continues to this day. It is estimated that the number of people employed in established factories and the cottage industry, both in the city and surrounding areas, is 200 000300 000, with more than half of them involved in gem-cutting. The gemstone most associated with Jaipur is the emerald, but it also has been a major tanzanite-cutting centre.

“It promises to be a spectacular congress,” says Gaetano Cavalieri, CIBJO President, “and the first to be held in person since 2019, before the onset of the pandemic. For many of us, it will be an opportunity to meet face to face after more than three years and I can’t think of a more appropriate and exotic setting to do so. My thanks to our Indian hosts and especially our CIBJO Vice-President Pramod Agrawal, who’s also the NGJCI Chairperson, as well as to Vipul Shah, the GJEPC Chairperson.”

A dedicated 2023 CIBJO Congress website will be launched shortly.

Robust discussions during KP Intersessional in Zimbabwe

The 2023 Intersessional Meeting of the Kimberley Process (KP) concluded in Victoria Falls, Zimbabwe at the end of May this year. Addressing the closing session of the gathering, World Diamond Council (WDC) President Feriel Zerouki was positive about the headway made during the four-day event.

“Decisions of the KP are taken at plenary meetings, so the goal of the intersessional is to record progress – and we seem to have achieved that on a number of key issues,” she said.

Turning first to the review and reform cycle that began this year, and more pointedly to the work of the sub-team on what constituted a “conflict diamond”, Zerouki strongly reiterated the council’s position that the expansion of the conflict diamond definition was essential. She emphasised that the KP had been provided with the mandate to do precisely that.

To reach common ground on the definition, as well as some of the other issues being addressed by the Ad Hoc Committee on Review and Reform, a spirit of candour, trust and respect was essential, she said.

“As we’ve witnessed this week, through open and robust discussions, we’ve secured the necessary psychological safety to share views and positions in support of the reform. These fundamentals are paramount if we’re to guarantee reform of this important process and promote the precious mineral resource of which we’re all custodians – natural diamonds,” she stated.

Commenting on the work of the KP Secretariat Taskforce, which is chaired by World Diamond Council representative Wim Soons, Zerouki noted that consensus was reached on the terms of reference of the new body, which is scheduled to begin operating next year in the Botswana capital of Gaborone.

The taskforce was also close to agreement on issuing a call for candidates for the new position of KP Executive Secretary, she added. Issues that still needed to be resolved include the legal entity status of the secretariat and a host country agreement.

Zerouki voiced particular concern about the situation in the Central African Republic (CAR). “The WDC wants nothing more than to see the country in peace and prospering from the value of its mineral resources,” she said.

Expressing the WDC’s commitment to the CAR Monitoring Team’s work and objectives, she said the council was disturbed about

the accuracy of values being determined on diamonds exported from the country. They contradicted the very purpose of the monitoring team’s revised operational framework for approving exports from authorised green zones, which was created specifically to support increased revenues for the CAR, as well as ensure security and stability, she explained.

Zerouki said the WDC supported a KP review visit to the CAR, but noted that it could not take place until the safety and security of

the review team could be assured.

She also paid tribute to the hosts of the meeting – the KP Chairperson and the Botswana government. “Their hard work, organisation and hospitality have all contributed to the spirit of collaboration we’ve experienced over the past several days,” she said.

On a personal note, she thanked all the participants in the intersessional for making her first major KP gathering as President of the WDC a memorable one.

Rapaport launches natural pearl market

The Rapaport Group has launched a new market for certified natural pearls.

The Tender Auction Catalogue was published on 7 June, with viewing in Dubai from 11-15 June and in Bahrain from 18-20 June. The tender auction closed on 20 June.

GIA releases first sustainability report

“Understanding our impact on the environment, societies and communities in which we operate is integral to our important consumer protection mission,” said GIA President and CEO Susan Jacques, speaking about the launch of the first Gemological Institute of America (GIA) sustainability report on 2 June at the JCK Las Vegas show. “It's vitally important that we all act on our responsibility to the planet and its people, advancing the positive aspects of the gem and jewellery industry, and mitigating the negative.”

This first GIA sustainability report and strategy was developed in reference to the Global

Reporting Initiative (GRI) framework. It includes baseline achievements for 2022 on a range of social, environmental and governance (ESG) programmes, as well as the GIA’s 2025 sustainability strategy, Championing Transparency.

“To move from the concept of sustainability to concrete actions, it's essential to understand where we are and where we want to be, to develop a clear strategy and action plan,” said Johanna Levy, GIA Vice-President for ESG programmes. “At the GIA, this means working on our own operations – which we talk about in our report – and to support the industry in its sustainability journey through education and research.”

“Natural pearls direct from Bahraini divers operate under strict government supervision, ensuring protection of the natural habitat and environmental sustainability. DANAT – the Bahrain Institute of Pearls and Gemstones – has been instrumental in collecting, grading and certifying the pearls,” stated the group.

Only natural pearls were offered for sale and were certified natural by DANAT.

This inaugural report includes ESG data for all GIA affiliates in the nine countries where the institute has operations and ambitious, measurable targets, including:

• Reducing GIA’s greenhouse gas emissions by 50% by 2030.

• Building sustainability content into the GIA’s education programmes.

• Providing no-cost basic gemmology training to 15 000 artisanal miners.

• Advancing sustainability in the industry through traceability of gems and verification of pre-owned jewellery. The GIA will report on progress toward these targets in its 2023 sustainability report.

It means that you can benefit by dealing with a member of the Diamond Dealers Club of South Africa and be assured of:

• Reliability

• Ethical and honest conduct

• Accountability in case of grievances

• Legal expertise

• Prestige of its Members due to strict controls and criteria

• Confidence (the fifth “C”)

WHAT DOES ALL THIS MEAN TO YOU?

System for mercury-free processing of gold ore field test successful

The recent successful field test of an innovative system for mercury-free processing of gold ore is a significant advancement in the important effort to safeguard the health and safety and improve economic outcomes of artisanal, small-scale gold miners (ASGM) and their communities.

The field tests, conducted with approximately 60 miners in three communities in Colombia’s Chocó and Antioquia departments in mid-April 2023, followed several years of planning and technical analysis by the Alliance for Responsible Mining (ARM) and MercuryFree Mining (MFM), supported by a grant from the Gemological Institute of America. MFM selected GOLDROP, which uses an innovative, yet simple water-flow system to separate gold from other minerals, as the most promising option after reviewing the results of six processing technologies.

“The miners with whom we collaborated were genuinely excited about the GOLDROP system, foreseeing improvements in their gold recovery rates and a reduction in their reliance on mercury,” said Toby Pomeroy, Executive Director of MFM. “Initial results using the GOLDROP system are very promising, with fine gold recovery as well

as mercury from whole-ore amalgamated concentrates. Further analysis will quantify specific data proving GOLDROP’s effectiveness over various mining locales and ore types.”

The GOLDROP system, developed by John Richmond of Sluice Goose Industries and demonstrated at the 2023 AGTA GemFair, is a portable, easy-to-use, costeffective device that, according to laboratory findings, can capture more fine gold than traditional processing methods, including those using mercury. “GOLDROP produces some of the highest fine gold recovery I’ve ever seen,” said Juan Camilo Megía Mosquera, Unión Panamericana gold miner, one of the field test participants.

“The encouraging results of this test are a testament to the value of innovation and commitment,” said GIA President and CEO Susan Jacques. “This great success helps protect ASGM communities and addresses the growing consumer demand for greater sustainability in the gem and jewellery supply chain.”

The next step, targeted for completion in 2023, is a pilot project to analyse the GOLDROP system’s efficiency across three or four mining communities in Peru and Colombia.

Operations at Kareevlei mine remain suspended

BlueRock Diamonds has gone into administration and operations at the Kareevlei mine in South Africa will remain suspended amid heavy financial difficulties.

The company, whose main subsidiary in SA entered business rescue in February, is also unlikely to receive any final payout from mining activities to settle its outstanding debt, it said recently.

Administration in the UK is similar to

Chapter 11 in the USA. Control of the company transfers to insolvency practitioners, whose task is to try to save the company or get the best results for creditors.

Negotiations for the restructuring of Kareevlei are currently in progress and its mining licence has been renewed, BlueRock noted. Trading in BlueRock’s shares on London’s Alternative Investment Market will remain suspended. – Rapaport

Update on activities within the JCSA

THE FIRST SIX MONTHS OF THIS YEAR HAVE been busy ones for the staff at the Jewellery Council of SA (JCSA).

In an attempt to save costs, we now only employ three employees, being myself as CEO, Elsa da Silva as Personal Assistant and Darryl van der Linde as our Bookkeeper and Admin Support. We continue to work remotely until such time as we are in a better financial position to move into offices.

Besides the general daily activities, I can report on some of the pertinent accomplishments:

The JCSA invited members on behalf of the Department of Trade, Industry and Competition (DTIC) who partnered with GIZ, a German development agency, to capacitate SA companies wanting to understand the German market and its business culture. The initiative intends to attract companies with export potential from different sectors targeting Germany as a market for their products and services.

The Hong Kong Trade Development Council invited our member buyers to attend the HKTDC Hong Kong International Diamond, Gem & Pearl Show & HKTDC Hong Kong International Jewellery Show in March 2023. As a token of appreciation for their support, they offered the hotel sponsorship programme to facilitate their visit.

We invited members to sponsor jewellery prizes for our Valentine’s Day competition, the aim of which was to promote jewellery to the public as gifts marking that occasion.

The JCSA recently arranged for 10 manufacturing companies to exhibit at JCK Las Vegas, held in early June. Their trip was fully sponsored by the DTIC, including flights, accommodation, meals and a fully furnished stand. As the largest and most renowned jewellery trade event in the world, JCK boasted over 30 000 industry professionals from over 130 countries.

The JCSA continues to offer members an opportunity to participate on the Jewellex365 online business platform. Once the platform has been populated by wholesalers, manufacturers, suppliers and service providers, we will be in a position to market our members locally and internationally.

A very exciting recent announcement was the launch of Jewellex Africa 2023 for the first time since 2019. The show will be hosted at the Wanderers Club, Illovo, Johannesburg from 3-4 September and will be held on a smaller

scale, allowing suppliers, wholesalers, manufacturers and service providers to sell to the trade only.

For out-of-towners, the Wanderers Hotel is in walking distance of the venue and we are encouraging buyers to make a weekend of it. Enquiries can be made at the JCSA’s offices.

You may all be aware that National Treasury has amended the FIC Act. Of particular importance in it is that suppliers of high-value goods receiving payment in any form, not only cash, above R100 000 are now accountable institutions under FICA legislation. The JCSA has assisted members with guidelines, offering opportunities for training and webinars to educate jewellers.

topics on these platforms for retailers, such as legislation and urgent messages.

The JCSA approached SARS on behalf of some members who were experiencing difficulties receiving claims for Notional VAT as well as Import VAT.

The Mining Qualifications Authority, which is a Sector Education and Training Authority for the mining and minerals sector (including jewellery), invited jewellery employers to apply for discretionary grants for training.

The JCSA continues to circulate information about jewellery stolen in robberies, with the request that if they are offered such items to purchase, they contact the relevant authorities.

One of the most important legislative changes affecting our members has been the new VAT regulations, which introduced the domestic reverse charge that affects vendors buying and selling gold and gold jewellery. We have provided members with resources and offered guidelines, webinars and online question-and-answer sessions with the assistance of Metal Concentrators’ tax experts and ENSAfrica, who have provided amazing support to the industry.

Very importantly, crime has recently increased. Our Jewellery Council Risk Initiative is working closely with the Consumer Goods Council of SA and private security, the SA Council of Shopping Centres, insurance companies, the NPA and the SAPS, who have undertaken to give the jewellery sector priority in the fight to reduce crime.

The JCSA created a database, exclusively for members, of past employees who have resigned or been dismissed for reasons of performance or in suspicious or criminal circumstances. Members can contact the council when employing new staff to ascertain whether they were previously employed in the trade and whether they either resigned from or were dismissed from their jobs.

For legal reasons, we do not request or provide reasons for dismissals. However, members can contact previous employers to obtain references.

In terms of our retail members, the JCSA recently expanded the Crime Risk Initiative WhatsApp groups in Gauteng, KZN and the Western Cape to include other important

The JCSA has collaborated with a company that will be offering an AI and facial recognition service to the industry. In addition, we negotiated correct camera systems for member jewellers at affordable prices.

We recently assisted Anglo American Platinum in communicating its premier annual platinum jewellery design and manufacturing competition, PlatAfrica, to all jewellery designers.

The theme this year is “Emergence” and if you would like to enter, please let us know and we will put you in touch with the organisers.

There is also much more news that we have to share. For further information on any of the above topics, please e-mail us at: admin@jewellery.org.za.

SA JEWELLERY NEWS - JULY 2023 17 MESSAGE FROM THE CEO

FROM EMBRACING THE WORK-FROM-HOME phenomenon to improving how to attract and nurture diverse talents, both large and small adjustments born during the past two years will go on to create lasting shifts in the way businesses support their employees and prepare for the future.

Mike Freislich, a coach, trainer and the co-founder of We Do Change, shares the top six organisational changes which emerged during the COVID-19 lockdowns and how they will impact a team’s ability to become agile, modify and move forward.

Defining trends that will continue to impact businesses

Office obliteration

Employers have a tough decision – should they continue working from home?

It is a tough battle, especially when one considers the number of expensive office buildings that stand empty. However, the truth is that there are benefits to working from home. These include not having to commute to and from the office, which boosts productivity and morale, especially among introverted individuals.

So why would anyone want to head back to the office? Well, like it or not, we humans need to feel connected to thrive.

While more is possible in remote working environments, nothing beats escaping from eight-hour days in front of a computer screen. Even with a back-to-back meeting schedule,

being at the office means one can still enjoy a brief walk between meetings, a joke with colleagues or a hallway chat.

Never underestimate the value of an inperson format that allows us to feed off each other’s energy, movements, body language and eye contact.

Load-shedding troubles

Access to a reliable electricity source and good Internet connectivity is essential for any business, particularly those which have a remote working environment.

Our worsening energy crisis means that many South African businesses are without electricity during the working day, creating added stress for employees who are unable to conduct their roles and responsibilities properly.

SA JEWELLERY NEWS - JULY 2023 18 BUSINESS MANAGEMENT
The past two years have seen substantial change, especially in the workplace, where organisations of all shapes and sizes have had to navigate a new normal.
6

Load-shedding pressures cause distractions and disruptions to presentations and meetings and can have a negative overall impact on what is possible in terms of value creation. Things also take longer, at a time when the need to act and respond to change is more urgent than ever.

A struggling economy

Around the globe, everyone is feeling the pinch. In South Africa, the situation is amplified by fuel costs, compounded by the effects of state capture and an unreliable electricity supply.

Maslow’s Hierarchy of Needs tells us that if a person’s fundamental needs are not met, they will simply be unable to do their best work. I have noticed that people are more tired and emotionally worn out this year. This leads to sluggish productivity and elevated levels of apathy, which are serious problems when working as a team.

The need for rapid organisational response to change

The changes over the past two years have further exacerbated an already volatile, uncertain, complex and ambiguous world.

The urgent need to reinvent and change direction has caught leaders off guard, in some cases forcing them to make decisions that impact others.

We have seen major decisions handed down from leaders for execution without any context or consultation. While this is a necessary approach at times, it leads to demotivation. Everyone wants to feel like a valued member of a team whose views are appreciated. I have seen many instances over this year where better communication and inclusive decision-making would have led to far better results.

Stimulating new ways of thinking

Allowing people the space to breathe is crucial. Many of us have felt stuck in our jobs, while constantly facing challenges that impede progress.

Attending training with an experienced external coach is an effective way of unearthing new ideas and understanding how to implement them into your organisation.

Participating in a training course can be a terrific way to disrupt one’s current way of thinking and create new opportunities for improvement. It enables a complete re-think of one’s operational needs to create value more effectively.

In flight-level thinking, for example, we talk about “agile interactions”, rather than meetings, to become explicit about intended purpose, format, outcomes, inputs and participants. The aim is to examine and replace the abundance of meetings with a smaller set of truly focused interactions.

Businesses need to be open to reinvention in the new norm. For example, consider shortening all meetings by 10 minutes to afford people the time to move around and regroup before the next meeting or Zoom call.

Taking care of mental health

This is one of the biggest health crises, but is often hard to spot. When somebody is behaving below perceived expectations, it is important to generate empathy. One way of doing so is by pausing before responding and considering no fewer than five plausible reasons they are behaving that way. This

technique can greatly improve one’s own responses in difficult situations.

Communication is always one’s best friend in these circumstances. Employees need to feel reassured that leaders are understanding and that help is available to them, if required.

Humans are complex. We each have our own feelings, views and thoughts. Consult your people and find ways to co-create solutions. Solutions built together are more widely accepted than those imposed from the top and are more likely to benefit everyone. While this approach takes more effort, the positive effects are long-lasting.

De Beers on pace to deliver on ambitious 2030 sustainability goals

THE DE BEERS GROUP’S 2030 SUSTAINABILITY goals span four pillars: leading ethical practices, partnering for thriving communities, protecting the natural world and accelerating equal opportunity.

During 2022, the group saw advances across all four “Building Forever” pillars and all 12 goals, which include reductions in water use and energy intensity, innovations in diamond-tracing technology, increased representation of women in senior leadership and progress towards its climate commitments.

A notable milestone was setting emission reduction targets across scopes 1, 2 and 3, which have been validated by the ScienceBased Targets initiative (SBTi). De Beers’ near-term SBTi-validated targets are to reduce absolute scopes 1 and 2 emissions by 42% and absolute scope 3 emissions by 25% by 2030. In setting the targets across all three scopes, De Beers is extending its climate ambition over and above its existing commitment to be carbon-neutral across scopes 1 and 2 emissions by 2030.

The SBTi-validated targets represent the reductions required by the organisation to align with the goals of the Paris Agreement on climate change. However, under its existing carbon-neutral commitment and with the implementation of its “Reduce and Replace” strategy, the group expects to exceed its SBTi-validated targets for reducing scopes 1 and 2 emissions by 2030.

De Beers also accelerated the pace of innovation and investment in its blockchain provenance platform, Tracr. The platform was deployed at scale in 2022 and enables participants to provide assurance of a

diamond’s source as it travels through the value chain. More than half of De Beers’ global production by value is now being registered on Tracr, which was recently named by Forbes as one of the world’s 50 leading blockchains for the third time.

“De Beers has a simple belief that informs everything we do: the diamonds we discover belong to the communities and countries in which they're found. We're inspired by the beauty and rarity of natural diamonds and the natural world, and we know how precious diamonds are – not only for the people who wear them, but for all those they touch along the way,” said Al Cook, the group’s CEO.

“‘Building Forever’ is about taking a long-term view. We work hand-in-hand with the communities in which we live and work to shape a better future. Our actions range from addressing the climate crisis to growing prosperity wherever we operate and by using our proprietary technologies, we can now connect our customers to the origin, impact and stories of their diamonds. ‘Building Forever’ will continue to guide every decision De Beers makes and touch every diamond we discover.”

“De Beers is committed to advancing industry standards, enhancing the transparency of diamond provenance and improving the livelihoods of artisanal miners,” said the group.

Key highlights of the group’s progress update include having increased the number of entities participating in the Best Practice Principles, the company’s set of leading ethical, social and environmental standards which are independently audited, to 2 690

from 2 283 in 2021. The miner also increased the number of mine sites participating in GemFair, De Beers’ programme to support the formalisation of the artisanal mining sector, to 263 from 219 in 2021. In addition, the programme provided fair and equitable finance to support the operations of 49 members.

Protecting the natural world

For its business and host communities to thrive, the mining giant must protect the natural world. In all of its activities, it follows best practices for biodiversity and water management, air quality, greenhouse gas emissions, waste and mine closure and rehabilitation.

In this regard, key highlights of its progress report included that it had:

• Achieved a 14% reduction in freshwater withdrawals and a 4% reduction in energy intensity compared with 2021.

• In partnership with Anglo American and EDF Renewables, commenced development of more than 70 MW of renewable energy projects in southern Africa.

• Invested US$2 million in Kelp Blue, a start-up that grows underwater kelp forests off the coast of Namibia, which can absorb carbon up to 50 times faster than landbased forests. In addition to supporting De Beers’ carbon-neutral commitment, Kelp Blue will create jobs and support sustainable economic development in Namibia.

• Marked the 20th anniversary of the Diamond Route, the 202 343 ha network of conservation sites that De Beers manages across southern Africa, protecting more than 50 mammal species.

• Continued Okavango Eternal, a partnership with National Geographic to protect the critically important headwards of the Okavango Delta. Progress included installing innovative water-monitoring technology, deepening research and understanding, and engaging with communities on soil-friendly farming methods.

Partnering for thriving communities

De Beers reiterated that it was focused on working with a range of stakeholders to help build a sustainable future and contribute to a better quality of life in its host communities, with particular emphasis on health and well-being, education and skills development, economic diversification and livelihood support.

In this regard, key highlights included that it had:

• Marked two decades since the introduction of its pioneering programme to provide free and confidential treatment to employees and their families living with HIV/Aids. The programme has helped save an estimated 650 lives during this time and has also ensured that there have been no cases of mother-to-child HIV transmission among employees or their partners for 14 consecutive years.

• In collaboration with Right to Care, rolled out a community-orientated primary care partnership to strengthen medical clinics in southern Africa, prioritising areas that lacked medical provision.

• Supported 420 students in securing 12-month internships in different sectors through a partnership with the International Youth Foundation.

• A total of 18 southern African-based companies completed the Stanford Seed Transformation entrepreneurship programme which De Beers supports in partnership with Stanford University.

• In total, more than 3 340 jobs were supported by De Beers through various socio-economic development projects and initiatives and 71% of its goods and services were procured from local suppliers.

Accelerating equal opportunity

Finally, De Beers again emphasised its focus on accelerating economic inclusion and

supporting diverse voices to help shape the future of its business, host communities and society at large, with a particular focus on addressing the historical under-representation of women in its talent pipeline and encouraging fresh and diverse talent into the diamond jewellery sector. In this regard, key highlights included:

• At the end of 2022, women comprised 33% of senior management positions within the De Beers Group (up from 31% in 2021).

• The group extended its partnership with WomEng, a highly regarded social enterprise committed to helping women and girls pursue careers in engineering and technology, for another three years.

• Since 2018, De Beers has provided 89 scholarships to women studying STEM at universities in Canada, has reached more than 3 700 school pupils in southern Africa through STEM workshops and has supported more than 2 400 women entrepreneurs to grow their businesses.

• The group provided funding for a free 12-week jewellery-making course for teens in New York City, which aims to fill the void of limited access to jewellery studios for teenage designers. De Beers also established an internal Equity, Diversity & Inclusion Council comprising volunteers from across the business to deepen understanding of the company’s diverse workforce and further cultivate an inclusive culture.

Bridal category buzzing at JCK Las Vegas

WITH OVER 30 YEARS OF UNITING THE industry in Las Vegas, the JCK Las Vegas show continues to deliver an exceptional experience that serves all major segments of the jewellery industry.

Last year, JCK celebrated its 30th anniversary, welcoming more than 17 000 attendees and 1 800 exhibitors from around the world, with guests from 130 countries attending. Earlier this year, JCK was recognised by Trade Show Executive magazine for its excellence in “returning to business as usual” following COVID-19, with TSNN awarding its 2022 show the Comeback Winner for Outstanding Attendance.

“Our goal is always to be the industry’s single greatest jewellery event for doing business and connecting, offering jewellery professionals the invaluable education and networking they need to propel their businesses and careers forward,” say the JCK Las Vegas fair organisers. “Whether you’re a buyer, a designer, a manufacturer, a supplier or a student, JCK’s a show you should be at every year.”

Jewellery insider and SA Jewellery

News international correspondent Smitha Sadanandan spoke to some of the renowned international brands which launched new bridal collections at this year’s show:

Ben Bridge

“We continue to see an uptick in elongated shapes in engagement rings – and it won’t be stopping anytime soon. Everything from ovals to pears and emeralds continue to be on the top of our fancy shape list,” says Molly Peterson, Bridal Buyer for Ben Bridge.

“We’re also seeing wide diamond bands that go beyond the traditional single-stone engagement ring being popular at the moment.”

Many of the latest trends in bridal jewellery were reflected in the styles and collections introduced at this year’s JCK Las Vegas.
SA JEWELLERY NEWS - JULY 2023

Hearts On Fire

Hearts On Fire’s new Vela bridal collection offers modern sensibility and draws on curves and swooping lines of a feather – a design element that appears discreetly in all 11 pieces of the collection.

The diamond engagement rings at the heart of the Vela collection mirror the lightness and shape of a feather floating through air, with a unique and elegant winged setting crafted with no bridge and minimal metal. The innovative design fills the stone with light and maximises the brilliance of the diamond. Each four-prong setting allows for a 360˚ view of the stone and holds it high.

Joshua J Fine Jewelry

“We’re seeing brides select rings with wider bands over the super-thin shanks that were popular during the past few years,” says Joshua J Fine Jewelry Director of Sales for Western USA, Adam Graham. “We’ve also seen an increase in yellow gold this year. Simpler, classic designs and more fancy shapes in jewellery and wedding bands are trending.”

Kirk Kara

“At JCK Luxury, we showcased new collections, including hidden halos, couples’ rings and rings inspired by motifs such as leaves, vines and blossoms,” says Angela Karaguezian, CEO and designer at Kirk Kara. “We’ve noticed an increase in demand for multi-stone rings that aren’t the traditional three-stone ones, but have multiple stone baguette sides or fancy side-stones featuring pears, ovals or trapezoids.”

Le Vian

“This year, the bridal trend surges towards natural-coloured precious gems and coloured diamonds,” says Eddie LeVian, CEO of LE Vian.

“We’ve noticed that the emerald cut is trending this bridal season, while the doubleclaw for centre stones has been the setting that’s on trend.”

Norman Silverman

“Our advice to couples who ask about bridal trends is that it’s important that you love what you pick. Invest in the centre and don’t be afraid to choose trendy, if that’s your style, as changing the ring in a few years is a minimal investment. Love it and wear it with pride. Don’t worry about what others think, as your opinion is the only one which matters,” says Trudy Tracy, Norman Silverman’s in-house diamond stylist.

“Large stones on a simple band and centrestones in an east-west setting, prong-set and bezel settings are on trend at the moment,” she adds.

Rahaminov Diamonds

“Our continuous bezel-style ring is new and was launched at JCK Luxury 2023. It’s a very clean and chic design,” says Melanie Goldfiner Goldberg, Director of Marketing and Business Development at Rahaminov Diamonds.

“Solitaires and engagement rings with hidden halos are very much in demand, with less of a demand for traditional halo styles. However, our cluster-style rings with larger diamonds are still best-sellers. Bezel-set rings are also popular – the focus is less on dainty designs. It’s more about comfort, style and everyday wear.”

Meet the team behind Piccolo Fine Designer Jewellery

Established in 2008 by Johann Claassens and his wife Suvette, who were joined by director Christian Oldewage in 2020, Piccolo Fine Designer Jewellery offers a full range of jewellery services to the trade, including high-quality CAD designs, 3D wax models, casting, stone-setting, semi- and total finishes. The team tell us about the lessons they have learnt, what inspires their creativity and the advice they would offer aspiring jewellery designers.

WITH A CLIENT BASE OF MANUFACTURERS, designers, makers, retailers and private clients, Piccolo Fine Designer Jewellery fiercely upholds its standards of excellence and attention to detail.

The enterprise comprises a small, but hard-working and passionate team. Johann does all the custom designs using modern computer-aided design (CAD) programs. Suvette, who holds a BTech and taught jewellery design and manufacturing for five years, does all Piccolo’s benchwork and finishing. Christian also does design work and helps when Johann is engaged in too much work. In addition, he does all the technical work, such as 3D wax printing up to and including metal preparation and casting. Each team member has a very fine eye for detail and between them, they have more than 28 years of industry experience.

SAJN had several questions for the team.

JOHANN

When did you first realise you wanted to pursue a career as a jewellery designer?

To be honest, designing jewellery was never the plan. I studied fine and applied arts, hoping to become a glass-blower. I met Suvette on campus while she was studying jewellery design and manufacturing. I helped her with a few designs and that was how I entered this space.

What is the most important jewellerymaking skill you have learnt?

Measure, measure, measure – and measure again! This does not only apply to making jewellery, because no matter how good you are at any of the other skills involved in the process, if something doesn’t fit, it doesn’t fit. For example, I may cast a platinum ring exceptionally well, but if I had the measurements wrong, I’ll have to start again from scratch.

What inspires your creativity when making a new piece of jewellery?

For me, it’s about the diamond or gemstone the client wants to use, as well as the story

behind why they want that particular piece made. I like making pieces for specific occasions, such as an anniversary using a client’s grandmother’s diamond, or her earrings for a 21st birthday. The reason for the piece and what I have to work with are where I get my inspiration.

What is the biggest lesson you have learnt in your career?

That you’re never too old to learn something new and you should always be open and willing to change with the times. I’ve also learnt that something I find pretty isn’t necessarily pretty to someone else, and that’s OK. People differ and so do tastes, so when it comes to something as personal as jewellery, it’s important that the wearer really likes it and is happy with it. That’s what really matters.

SA JEWELLERY NEWS - JULY 2023 26 COVER FEATURE

SUVETTE

Who or what is your biggest inspiration?

Art Nouveau jewellery and jewellers.

What does a typical day at work look like for you?

We start off by casting for the day’s jewellery to be manufactured for private and/or trade clients. Thereafter I work mostly at the bench, finishing off jewellery pieces, prepping pieces for setting and doing finishing touches on pieces before they go out for delivery. I also help with casting preparations for the next day, as well as seeing clients and suppliers.

What are the most treasured items in your personal jewellery collection?

I have a salt and pepper diamond wedding ring that I love. The main cognac diamond is surrounded by small, but prominent shades of light brown to cognac-coloured diamonds. The entire ring’s finished with filigree work and intricate hand-engraving. I also treasure my first Art Deco-inspired wedding ring.

What is your power principle?

Have passion for what you do every day and do whatever you do with passion.

CHRISTIAN

What first led you to jewellery design?

I had an interest in 3D printing and that led me to start designing. I started off designing functional parts for everyday life, but as I learnt more about the programs, I changed my direction of designs to jewellery.

Piccolo Fine Jewellery’s services to the trade include:

Design – Supplying high-quality CAD designs for jewellers using the latest technology is one of Piccolo’s core services. “We help jewellers transform their client’s idea from a picture or pencil sketch to a CAD drawing, ready to be printed in wax,” says Johann. An added benefit for jewellers is that the Piccolo team knows what to look for and design in such a way that the rest of the steps, including casting and setting, not only go easily, but result in a good product. Design programs are also very expensive, so jewellers save thousands of rand by paying us for a design instead. “In addition, our turnaround time’s quite fast, which means the jeweller’s client doesn’t have to wait long,” adds Johann.

Wax printing – Piccolo uses the CAD drawings it receives from jewellers or that it has designed for them to print topquality, 100% wax models which are ready to be cast. It has a number of machines that are updated regularly in order to do so. An added benefit for jewellers is that no matter how many times a wax model needs to be printed, clients only pay Piccolo once. “The stress that goes with wax models becomes our problem, not theirs, which means the jeweller has one less thing to worry about,” says Johann.

What are your favourite materials to use?

My favourite material doesn’t go into the end product, but I really enjoy working with the 3D printed wax parts. It’s a very delicate process that requires patience and fine motor skills.

What’s your favourite piece of jewellery that you’ve designed?

This year’s PlatAfrica piece that I helped Johann design. It was inspired by a Californian poppy and took some organic modelling on my part to make it life-like. I’m very happy with the way the design turned out, once casted.

What advice would you offer aspiring jewellery designers?

Spend some time behind the workbench casting the pieces yourself to learn what does and doesn’t work in the design process, with regard to tolerances and stone settings.

Casting – Piccolo uses 3D wax models to make moulds. High-quality investment powders are used for the moulds for the wax casting process. After many years, Piccolo has seen that waste investment powder works best for different alloys. The team cast in platinum and palladium, as well as all kinds of gold alloys. “This means that jewellers don’t have to deal with the costs of all the different elements needed to cast,” explains Johann.

Finishing – With more than 25 years’ of collective experience, the Piccolo team finish castings for other jewellers with exceptional quality. Castings that have been finished then only require setting, which the jeweller can either do with Piccolo or use their setter of choice.

“There’s a big ‘loss’ on metal when it comes to finishing, which is expensive and can only be recovered through equally expensive refining. When Piccolo does the finishing for jewellers, they don’t have to worry about those losses and costs, as they only pay for the metal they get when the piece is done,” says Johann.

Setting – Piccolo can also handle the setting of jewellery. Its stone-setter has more than 15 years’ experience in the field.

Colored Stones from the Deep

Colored Stones Unearthed

Aaron C. Palke | James E. Shigley SPONSORED BY

Minerals used as gemstones are all around us – for example, feldspar minerals [(Na,K,Ca)Al1+xSi3-xO8] and quartz (SiO2) that make up the bulk of the earth’s crust – and if we were to observe the earth’s mantle down to about 400 km deep, we would find an abundance of the mineral olivine [(Mg,Fe)2SiO4], known as peridot in the gem trade (figure 1). However, most minerals we encounter would not be considered gems due to their small grain size, lack of transparency, undesirable colors, or lack of durability for ornamental purposes. Gemquality minerals require very specific conditions of pressure, temperature, and chemistry to occur. These unique geological environments are quite uncommon, leading to the rarity of fine-quality gemstones in the earth.

In previous issues of Gems & Gemology, the “Diamonds from the Deep” column addressed aspects of current research on diamond geology. To a geologist, diamonds and their inclusions are ideal tools to study the deep earth (below about 35 km), a region totally inaccessible to traditional geological studies

involving field mapping and petrological observations of hand samples collected at or near the earth’s surface. On the other hand, most colored gemstones are formed in the crust—the outermost rocky layer of the earth, reaching down to a depth of roughly 35 km. Still, colored stone deposits are geologically diverse, and many gem-quality crystals do come from the earth’s mantle or the very deepest parts of the crust. The formation of colored stones from the crust-mantle transition and below will be the focus of our first instalment of this new column. Future instalments will appear in the journal on a periodic basis and will focus on geological concepts related to colored stones that readers now regularly encounter in articles on gems and gem localities. If there are topics of interest for future instalments, readers are encouraged to contact the column editors.

Colored Stones and the Deep Earth

We will now describe some of the colored gemstones that provide important information on the mineralogy, composition, and evolution of the earth.

Peridot. If one wanted to lay hands on a rock formed deep in the earth’s mantle, the barren deserts in northern Arizona would be the place to go. On the San Carlos Apache Indian Reservation, there are fields of geologically recent (~one-million-year-old) lava flows containing xenoliths of the mantle rocks these magmas passed through on their way to the surface. The alkali basalts in this area are a dull, dark gray color, but occasionally they contain

vividly colored nodules composed of crystals or grains of apple green olivine and darker green pyroxene [(Ca,Mg,Fe)SiO3] minerals (figure 2). San Carlos Apache tribal members mine the basalts to recover the gemmy olivine (peridot) contained within the nodules. Because the peridot-bearing nodules are considered a close analogue for the bulk composition of the earth’s mantle, the olivine is widely used as a starting material for experimental geochemical studies aimed at interpreting the dynamics and evolution of the mantle (e.g., Kubo et al., 1998; Liu et al., 2005; Tollan et al., 2018). Similar xenolith-rich alkali basalts found in China, Australia, and Vietnam provide information on the composition of the earth’s mantle since, as stated earlier, olivine is a principal mineral phase.

Volcanically Sourced Sapphire and Ruby. Another glimpse deep into the earth comes from volcanically associated rubies and sapphires. These types of gem corundum (Al2O3) are found predominantly near the continental margins of Australia and Southeast Asia, where they are associated with voluminous alkali basalt extrusions that acted as the mechanism of transportation to bring these gems to the surface. Some volcanically transported sapphires are found in the U.S. state of Montana, as well as where other volcanic formations such as rhyolites (silica-rich volcanic rocks) or lamprophyres (potassic,

magnesium-/iron-rich volcanic rocks) would have been involved. In contrast to many colored stones, these sapphires and rubies formed in an extensional rather than a compressional tectonic setting in the crust. In this situation, thinning of the crust allowed for upwelling and eruption of magmas largely derived from the mantle, such as alkali basalts. It is important to point out that the sapphires and rubies were only transported by these basalts—not formed within or by the basalts themselves. Analysis of inclusions within the basalt-related gem sapphires— including feldspar, pyrochlore [(Na,Ca)2Nb2O6(OH,F)], zircon (ZrSiO4), and melt inclusions—indicates their formation from syenitic-type magmas. These sodium-rich silicate magmas likely formed near the boundary between the earth’s crust and mantle and may be related to metasomatism, or the circulation of hot fluids, in the earth’s mantle (Graham et al., 2008; Giuliani and Groat, 2019). The basalt-related rubies likely formed from a more aluminous and mafic (magnesium- and iron-rich) protolith. The rubies have been suggested to have formed through metamorphism of such protoliths, although the identification of melt inclusions in these basalt-related rubies suggests the involvement of melting or magmatic processes in their formation (Palke et al., 2018).

Deep Crustal Gems. The rocks at the earth’s surface contain a tremendous record of the geological evolution of our planet. Since the beginning of the earth’s history, the primary dynamic force has been the slow transfer of heat from deep in the core

and mantle to the surface. This heat transfer is the engine for convection in the mantle and the slow drift of the tectonic plates at the surface. Earth’s continental crust has grown and evolved with these processes, meaning the crust serves as a sort of record of tectonic activity. Many geologists have spent their careers tracing out fault lines, dating rocks, and connecting the dots on geological formations to understand how the continents have been variously ripped apart and sutured together again. Geologists specializing in tectonics use specific tectonic events, especially orogenic (or mountain-building) events involving the collision of two or more continents, as markers of the passage of geological time. In fact, most colored stone deposits are the direct result of these collisional orogenic events, with the intense heat, pressure, and fluid movement generated acting as the catalyst for crystallization of gemmy crystals of corundum, beryl (Be3Al2Si6O18), and garnet [(Ca,Mg,Fe)3(Al,Fe)2Si3O12].

However, some of these gems were formed at more extreme conditions and record a view of the deep earth not seen in most other precious stones.

Modern collisional tectonic events are generally initiated with subduction of oceanic crust beneath the continental crust and down into the mantle. Subduction of the oceanic crust has been linked to the formation of deep diamonds as far down as the lower mantle (Smith and Nestola, 2021). This process is also responsible for the formation of one of the most sought-after colored stones: jadeite jade (figure 3). A high-pressure mineral

Figure 4. Schematic diagram of a jadeite formation environment in a subduction zone. As oceanic crust is subducted, material builds up in an accretionary prism. Further down, jadeite forms in a high-pressure serpentinite mélange at roughly high-pressure, low-temperature (HPLT) conditions. To reach the surface, this jadeite must be transported from 20 to 80 km in exhumation channels. Lithological variations and thermal structures are modified after Gerya (2011). High-pressure serpentinite mélange, location of exhuming high-pressure rocks, and environment of jadeite formation are based on Stern et al. (2013).

rich in sodium, aluminum, and silicon, jadeite (NaAlSi2O6) is a unique record of the fate of rocks and fluids subducted into the earth. Estimates of the geological conditions for jadeite mineralization indicate depths from below about 20 km to an astonishing 80 km below the surface of the earth (Stern et al., 2013; Harlow et al., 2015). At these great depths, the immense pressure of the overlying rock column enhances the solubility in water of certain chemical components, including sodium, aluminum, and silicon. The fluids trapped by the subducted oceanic crust (mostly water) can dissolve these necessary chemical components from their host rock and migrate upward into the overlying mantle wedge including oceanic crustal rocks, and forming the so-called mélange matrix. As these fluids make their way up into the mélange matrix, the dissolved chemical components precipitate out and crystallize jadeite in veins representing the original fluid flow pathways. The truly astonishing aspect of this is the fact that these deep rocks can now be found right at the earth’s surface. Jadeite deposits represent the movement of subducted material from 20–80 km up to the surface in exhumation channels either during or after the cessation of subduction and collision (figure 4). Jadeite deposits are useful as markers and indicators, both geographically and temporally, of fossil subduction and collisional tectonic events.

One final example of a colored gemstone recording deep geological processes comes from the Dora Maira garnets found in the Italian Alps (figure 5). These are unique in the world in being nearly pure pyrope garnets (Mg3Al2Si3O12). Their formation would have required extreme pressures as

well as a very magnesium-rich and relatively iron-poor source (protolith). Petrological studies of these garnets and their host rocks indicate formation at depths of around 120 km (Chopin and Schertl, 1999). This means Dora Maira pyrope garnets formed in the diamond stability field at a depth where some lithospheric diamonds may have been sourced (Hermann, 2003). The Dora Maira garnets could only have formed in what were originally continental crustal rocks, which generally cannot be subducted to such great depths due to the generally buoyant nature of the continental crust. The Dora Maira deposit is proof that in some extraordinary conditions during continental collisional events, some continental crust can be essentially subducted into the earth. What is even more surprising is that age-dating of zircons associated with these garnets suggests that the Dora Maira mass would have moved from a depth of around 120 km in a timescale of only 5–6 Ma, an astonishingly brief period in a geological sense. Colored Stones and the Earth’s Crust Geological study of the deep earth is fundamental to an understanding of plate tectonics, the earth’s evolution, and the overall dynamics of our planet. However, most colored stones are formed through geological processes at work from a few tens of kilometres deep right up to the earth’s surface, essentially. The interplay between the solid, rocky crust and the hydrosphere (all the earth’s water), the atmosphere, and the biosphere (all the earth’s life) gives rise to an enormous diversity of geological conditions, many of which are capable of producing fine gemstones through geological timescale. The processes occurring in the earth’s crust that are responsible for colored gemstone deposits will be the primary focus of future instalments of this column.

BOX A: HOW DO WE KNOW THE INTERNAL STRUCTURE OF THE EARTH?

Figure A-1 shows the layered structure of the earth. The crust makes up the uppermost rocky layer down to about 35 km, with the mantle below. The mantle extends down to about 2,890 km and is divided into three parts: the upper mantle, the lower mantle, and an intermediate transition zone between the two from 410 to 660 km. The divisions are based on major changes in the mineralogy and physical properties of each layer. While the crust is mostly made up of quartz and feldspar minerals, the mantle is more magnesium- and ironrich and silica-poor. The upper mantle is believed to be dominantly composed of minerals olivine, garnet, and pyroxenes. The major distinction between the upper and lower mantle is the transition to a mineralogy dominantly composed of bridgmanite [(Mg,Fe)SiO3] in the lower mantle with various phase transformations occurring in the so-called transition zone. Below the mantle is the core from 2,890 km to the earth’s centre. The core is made of an iron-nickel metal alloy and is divided into the solid inner core and molten outer core. Meteorites represent planetary cores formed at very different pressures and temperatures, and their minerals, such as olivine, are used to understand Earth’s core and structure.

But first, how do we know what we claim to know about the interior structure of the deep earth? The furthest underground humans have gone to directly observe deep rocks is 4 km below the surface at the Mponeng gold mine in South Africa. The deepest rocks brought to the surface directly in drill core sections have come from the Kola Superdeep Borehole in northwestern Russia, which reached depths of 12.26 km. However, this is only a fraction of the expected thickness of 35 km for the continental crust in this region. Indirectly, by geophysical methods and/or by analyzing parts of the deep earth brought to the surface by geological processes, geoscientists have been able to reconstruct the earth’s interior. Geoscientists can use several ways to study the interior of the earth:

1. The study of rocks, formed deep in the lower crust or upper mantle, that are brought to the earth’s surface by geological activity.

The collision of two continental plates can create conditions where one plate is carried (or subducted) by tectonic forces beneath an adjacent plate. This subduction can transport crustal rocks down into the upper mantle,

where they undergo metamorphism. Because they are less dense than the surrounding mantle rocks, these altered crustal rocks are sometimes gradually lifted back toward the surface and often carry with them pieces of mantle. When exposed at the surface by erosion, they become accessible to geologic study.

Volcanic eruptions, which produce igneous rocks such as basalt and andesite, occur along mid-oceanic ridges and above subduction zones. Igneous magmas can incorporate fragments of rocks (called xenoliths) as well as minerals (called xenocrysts) from regions of the lower crust or upper mantle through which the magmas pass. The example most familiar to gemologists is the transport of diamonds from deep in the earth to the surface by kimberlite or lamproite magmas.

2. The study of inclusions in lower crustal or upper mantle xenocrysts (crystals of different origin (xeno-) included within an igneous body such as diamond, garnet, olivine (peridot), and pyroxene) that sometimes incorporate inclusions of mineral grains that originated from the deep environment of xenocryst formation. Inclusions in diamonds are particularly important as they are insulated deep in the earth from alteration and other mineralogical changes over extended periods of geologic time. Some mineral inclusions containing certain radioactive elements can be age-dated to give some idea of when the host xenocryst formed.

3. Experimental studies carried out in a laboratory can also be used to understand the deep earth. Several types of high-pressure and high-temperature experiments can be conducted in order to better understand the formation, physical properties, and behavior of minerals and rocks under lower crust and upper mantle conditions. Such experiments allow geoscientists to verify observations of geological features made in the field. In these experiments, researchers artificially recreate the expected chemical composition of various parts of the earth – either the crust or mantle – and apply high pressures and temperatures to simulate conditions deep in the earth. Recovery of the experimental charge can allow insight into the mineralogy and composition of the deep earth.

The use of a diamond anvil cell allows researchers to subject small fragments of a test material to extreme

ISSUE 6

pressures by compressing the material in a pressure medium between the polished culets of two small diamonds. A tiny piece of ruby is included within the cell as a pressure indicator (since the wavelengths of the fl uorescence emission of ruby are known to change with pressure). The test material within the cell can be heated by external or internal means. It can also be viewed through the transparent anvils. While at high pressures such as those existing within the earth, the test material can be studied by absorption and emission spectroscopy and X-ray diffraction techniques.

4. Geophysical studies allow us to measure and record time and intensity variations in energy and other types of signals travelling through the earth. These methods help determine changes in physical properties such as density and acoustic behavior among different rock types. Anyone who has ever

experienced an earthquake knows that energy waves travel from the source of the event. With an extensive network of seismometers deployed around the world, scientists can document the trajectories of seismic waves from earthquakes and underground explosions. These seismic waves can travel along the surface and below the surface, where they can be reflected through or refracted by the different internal zones. In an analogous fashion, variations in magnetic, gravitational, electrical, and electromagnetic signals (measured at the surface and in boreholes and sometimes obtained by regional aerial surveys) can also help us understand the earth’s internal structure.

5. Planetary studies and meteorite research have allowed scientists to gain information about the earth’s interior. Meteorites originate from inside the solar system, and most are fragments of asteroids that broke apart long ago in the

of the earth, as these are thought to have “primitive” compositions representing the original composition of the solar system. The compositions of these chondritic meteorites can also be used as a proxy or an estimate of the bulk composition of the earth.

SSEF launches global service for melee diamonds down to 0,5 mm

The testing batches were doped with both synthetic diamonds and diamond simulants, all of which were detected and sorted out by the ASDI-500 device.

pleased make available this new authentication service to our customers,” said Jean-Pierre Chalain, Project Manager and Director of the diamond department at the SSEF.

THE ASDI-500, DEVELOPED WITH SWISS robotics company UNIMEC SA, is able to screen very large quantities of round, colourless, polished melee, detecting and extracting synthetics and simulants from among the natural diamonds.

The positive results from testing ASDI500 have provided a green light for the inauguration of a testing service for round, colourless diamond melee down to 0,5 mm in size for both the Swiss and international diamond and jewellery trade.

The validation programme began after the SSEF and UNIMEC SA first introduced the ASDI-500 at the GemGenève Show in November 2022. The programme involved the screening of more than 500 000 round diamonds with diameters ranging from 0,50-3,80 mm, using a strict double-checked internal procedure.

The ASDI-500 device uses a built-in high-precision robot entirely manufactured by UNIMEC SA. It picks up the diamonds individually, latching onto them while they are in the pavilion-up position. A special nozzle was designed so that the diamonds’ culets are never in direct contact with the robot’s pick-and-place mechanism. This protects the tip of the diamond, or culet, from any damage during the testing procedure.

“Ten years after launching the ASDI device, the first-ever device developed to authenticate large batches of small diamonds, the SSEF and UNIMEC are proud to offer the diamond industry the ASDI-500. This is a nextgeneration instrument that allows automated diamond authentication, especially in the size segment of 1,00-0,50 mm, for which no automated solution existed thus far. We’re

“To sustain consumer confidence, it’s necessary to develop high-quality and reliable screening solutions that have been adapted to watchmaking needs,” said Dominique Dubugnon, Head of the Gemmological Commission at the Federation of the Swiss Watch Industry FH. “It’s essential to maintain the high level of quality for which the Swiss industry is known.”

The ASDI-500 is being presented by UNIMEC SA (booth G42) at the EPHJ show (Geneva, 6-9 June 2023). Dr Michael Mintrone, Research Scientist at the SSEF, will deliver a presentation about ASDI-500 at the “Advances in Gem and Diamond Research and Technology” symposium running from 3-4 October 2023 in Mumbai, India.

Mikimoto observed that many of his pearls were bought by foreign sailors and tourists, and decided to open a shop in the entertainment district of Ginza, in Tokyo. The name of Mikimoto became one of the first Japanese brands to attain an international presence and recognition. He took advantage of every opportunity to personally promote the beauty and elegance of his pearls, presenting his works in exhibitions throughout the world.

There are 45 792 jewellery store businesses in the USA as of 2023. California has the highest number, with 6 594, New York with 5 522 and Florida with 4 748.

 The South African Mint released the very first Krugerrand gold coin in 1967. At a time of great political upheaval and uncertainty, SA made the decision to strike its own gold coin. While previous gold coins had been struck primarily for the rich, the Krugerrand gold coin was designed as the ‘working man’s coin’ - a coin for the hard-working wider population who wanted to preserve their savings.

 Jewellery in literature affects society. For example, people in Europe used to love opals. They were very valuable. Then Sir Walter Scott wrote a novel where the protagonist had an opal that touched holy water. She died soon after. This popular book led to a drastic decrease in the popularity of opals. To this day, people in many areas regard them as unlucky.

 Rubies obtain their colour from corundum. Pure corundum is colourless and made up of aluminium and oxygen. In order to gain colour, it must come into contact with small amounts of chromium. The chromium replaces some of the aluminium in the stone’s structure and it becomes a red ruby.
