Editor's note

“WINTER IS NOT A SEASON, IT’S AN occupation,” Sinclair Lewis once wrote. When the days are short and the air is cold, finding the motivation and energy to get up and about can be difficult.

I have found that the five best ways to elevate my mood during winter is to try and keep active, to go outside, to eat well, to get enough sleep and to meet up with friends and family. Positive news also always helps and this issue is full of exciting and feelgood industry features.

Jewellex Africa 2024, the continent’s leading jewellery trade show, promises to be exceptional once again, with two venues already fully booked and the third almost full. This year’s event will also have a special pavilion in collaboration with the Department of Trade, Industry and Competition. The two-day event will kick off with a Business Breakfast on Sunday, including an exciting guest speaker to be announced.

Entries are also open for this year’s PlatAfrica Jewellery Design Competition. It marks a momentous milestone for the global platinum industry: the 100th anniversary of the discovery of the Merensky Reef, the

world’s most prolific source of platinum group metals, right here in South Africa. 2024 also marks a momentous milestone for PlatAfrica as the 25th edition of the competition launches in celebration of the Merensky Reef centenary.

On 9 May, key industry stakeholders gathered at MetCon to celebrate the first Jewellery Excellence MasterClass graduates. Driven by the vision of equipping up-andcoming jewellers with the technical and business skills needed to take their creativity and businesses to the next level, this year’s graduates were Ayanda Zondi, Isabel Bothma, Kamogelo Phago and Mosiuoa Samuel Motitsoe. This issue shares more about this wonderful industry initiative, as well as the four talented graduates.

We hope that these, together with the other features in our June issue, lift your spirit during the colder days.

E-mail us your tips on how you beat the winter blues – we’d love to hear from you.

Happy reading!

Watches of Switzerland snaps up Roberto Coin for US$130 million

Watches of Switzerland has acquired the distribution rights to jeweller Roberto Coin’s North American markets for US$130 million, with plans to expand its wholesale business to independent retailers and beyond the USA.

The deal comes following a relationship of more than 10 years between the Rolex owner – which also offers brands such as Breitling and TAG Heuer – and Roberto Coin, with the latter’s jewellery already available in 16 Watches of Switzerland showrooms in the USA. The move will “significantly enhance” Watches of Switzerland’s strategic positioning in the luxury branded jewellery space in America, it said.

Watches of Switzerland will grow the wholesale business of Roberto Coin Inc, the jeweller’s USA-associated operation, it noted. That includes expanding its presence with independent retailers and growing its international market. It will also increase the number of its own stores that carry the jewellery brand, as well as open mono-brand boutiques and franchise stores.

The Coin family will retain a seat on the company’s board of directors and Peter Webster, co-founder of Roberto Coin, will remain President of the jewellery brand. He will report to David Hurley, North American President and Deputy CEO of Watches of Switzerland.

“We’ve partnered with Roberto Coin for over a decade in the USA, retailing its elegant jewellery in a number of our Mayors showrooms,” said Brian Duffy, CEO of Watches of Switzerland. “It’s a hugely popular, growing brand, occupying a strong position in the market. We believe there’s a significant opportunity to leverage our proven retail expertise in luxury branded jewellery. That category has consistently outperformed the wider jewellery sector and we see further strategic and operational opportunities for the business within the broader group.”

In 2022, Roberto Coin Inc reported annual revenue of US$146,2 million and profit before tax of US$30,1 million. Preliminary 2023 results indicate revenue of US$138,7 million and US$30,2 million in profit before tax, Watches of Switzerland added. – Rapaport

Jewellex Africa not to be missed

Jewellex Africa, the continent’s leading jewellery trade show, is set to return to the Wanderers Club in Illovo, Johannesburg on 8-9 September. Organised by the Jewellery Council of SA (JCSA), it boasts a rich history of connecting industry professionals, buyers and jewellery enthusiasts.

“This year’s edition promises to be exceptional with two venues already fully booked and the third almost full,” says Lorna Lloyd, JCSA CEO. “Due to demand, we’ve expanded the show to accommodate a larger selection of exhibitors.

“We’re also excited to share that we’re planning a special pavilion in collaboration with the Department of Trade, Industry and Competition and will be submitting an application to that department to fund 10-20 SMME companies to exhibit at the show.”

The two-day event will start with a

KP participants encouraged to enhance transparency

With 2024 being declared the “Year of Delivery” by the Chairperson of the Kimberley Process, World Diamond Council President Feriel Zerouki reminded delegates of the decision taken at the KP Intersessional meeting in Dubai that participants can choose to apply best practice over and above the minimum requirements of the process – in this instance, listing the countries of mining origin on the KP certificate when the information is available. It should also be highlighted and disclosed to maintain and secure confidence in diamonds.

“The industry’s moving forward with traceability and will complement these efforts by pioneering the technologies in which we’ve invested,” Zerouki remarked during the opening session of the Intersessional.

This Intersessional marked many “firsts”, notably the first time that a wide range of community members from across the global supply chain shared their diverse views with the delegates.

“These insights will enrich our discussion

Business Breakfast on Sunday, 8 September, sponsored by Rand Refinery. This year’s exciting speaker will be announced soon.

“We’re also excited to share that Brinks SA will again be sponsoring the lanyards, MetCon the carrier bags and Cape Precious Metals the registration,” says Lloyd. “Our sponsors have always been loyal supporters of the Jewellery Council and Jewellex Africa and have always had the industry’s interest and growth at heart, for which we thank them sincerely.”

Stand sales for Jewellex Africa 2024 are open and prospective exhibitors are invited to contact Elsa da Silva for further information on tel: (011) 484-5528 or 082-214-0028 or e-mail: elsad@jewellery.org.za.

not only on the expansion of the definition of conflict diamonds, but also on critically important issues of development, and will help us appreciate a fuller and more compelling natural diamond story,” she added. “We’d like to see more engagements, moving forward.”

Another first initiative of the KP Chairperson will be the holding of an ad hoc plenary session during the Intersessional, departing from the practice of holding such sessions only at the end of the year. “This is significant because, for the first time in the history of the KP, it will be possible to make decisions mid-year and, thereby, push for progress during this important ‘Year of Delivery’,” noted Zerouki.

Also, after years of collective efforts from KP participants and observers, this Intersessional marks the launch of the Kimberley Process Secretariat, led by its first Executive Secretary, which serves as recognition that the KP is crucial to advancing global governance and development goals.

“So, in a world full of uncertainty, we have unwavering confidence in our ability to navigate challenges together. One thing’s for sure: with increased transparency at the KP, the future of diamonds is bright,” said Zerouki.

FIC issues guidance on the definition of high value goods dealers

The Financial Intelligence Centre (FIC) has published public compliance communication (PCC) 58, to provide guidance on the interpretation of high-value goods dealers (HVGDs), as per Schedule 1, item 20 of the FIC Act, which has been circulated by the Jewellery Council of South Africa (JCSA) to

all its members.

The guidance also includes examples of money-laundering, terrorist financing and proliferation financing risks HVGDs face. PCC 58 has been issued in response to the amended Schedule 1 to the FIC Act, as contained in Government Gazette 47596

which came into effect from Monday, 19 December 2022.

For any queries, contact the FIC’s compliance contact centre on tel: (012) 641-6000, select option 1, or submit a web query by clicking on: https://www.fic.gov.za/ compliance-queries/.

Tim Schlick named CEO of Platinum Guild International

Tim Schlick has been appointed CEO of Platinum Guild International (PGI) after nine years with the organisation.

He has previously worked for businesses including advertising agency networks DDB China Group and McCann Worldgroup. He is a business strategist and marketing expert who has advised more than 30 Fortune 500 companies, said PGI.

Schlick said he would focus on having “PGI continue to create incremental value to its sponsors and trade partners, as well as

unlock new opportunities that create demand for platinum and drive global growth”.

He will be based in Europe, but he is also familiar with the Asian jewellery industry, having spent time in the region prior to relocating.

“I look forward to continuing to work closely together, as our relationship with Platinum Guild International is fundamental to building and supporting platinum’s growth in

the jewellery sector,” said Benny Oeyen, Executive Head of Market Development of global miner Anglo American.

“I feel excited and honoured to lead Platinum Guild International and work with our teams in the market to help them continue to bring market excellence to life in platinum jewellery,” said Schlick.

Pandora gets revenue boost from lab-grown expansion

Pandora raised its guidance for the full year following stronger-than-expected sales in its first quarter, driven by high demand for its labgrown diamond collections.

The Danish jeweller now expects revenue for 2024 to grow by 8-10%, compared with the 6-9% it previously stated, it said. Revenue for the first three months climbed 17% year on year in the first quarter to US$986,3 million, rising 18% on an organic basis – a similar metric to comparable-store sales.

The increase is the result of a gain of 87% on a like-for-like basis in the company’s synthetic diamond collection, totalling US$9,1 million. Pandora now sells its lab-grown diamond jewellery in 700 stores in the USA,

Canada, the UK, Australia, Mexico and Brazil, with North America accounting for the largest proportion of revenue. Additionally, the collection is creating a “halo effect” on the company’s other jewellery groupings, it noted.

Pandora also received a boost from the expansion of its network, it explained. During the period, it added a net 19 new concept stores and seven Pandora-owned shop-inshop locations. The jeweller’s focus on its Phoenix strategy to elevate the brand has also been effective.

Online sales rose 22% versus the same period a year ago – 24% on an organic basis –comprising 20% of total revenue. Meanwhile, profit rose 9% to US$139,3 million.

Sales in China were “challenging”, the company said, falling 17% on a like-forlike basis. However, Pandora is focused on enhancing the brand, noting that the mainland is a “strategic priority”. Strong sales in the USA and Europe, particularly in Germany, offset the drop in China.

“We’re very pleased with our start to the year as we embark on the next chapter of Phoenix,” said Pandora CEO Alexander Lacik. “While jewellery markets around us generally remain subdued, our ongoing brand investments allow us to take market share. We raise our revenue guidance and look forward to keep fuelling our growth with exciting strategic initiatives.” – Rapaport

GIA and AGS announce joint event for September 2025

Two leading gem and jewellery industry events will come together next year, offering insights into cutting-edge gemmological research, education, training and opportunities for gem and jewellery professionals to network on a global level.

Converge, to be held from 7-10 September 2025, will unite Conclave, the premier annual educational and networking event of the American Gem Society (AGS) and Symposium, the industry-leading research and education gathering of the Gemological Institute of America (GIA), held every five to seven years, into one powerful event.

“Combining the GIA’s strengths as a leader in education, science and pioneering research with AGS’s focus on professional development, business resources and networking provides a unique opportunity

to advance our shared mission to protect consumers and serve the international gem and jewellery community,” said AGS CEO Katherine Bodoh.

“This joint event will blend the best of AGS and GIA, harnessing each organisation’s unique capabilities to offer innovative educational and professional development programming, together with the latest scientific research in a unique environment,” said GIA CEO and President Susan Jacques.

Converge will take place in Carlsbad, California at the GIA world headquarters and the Omni La Costa Resort. The GIA and AGS anticipate providing further details, including programme, registration and accommodation information, in the near future.

Jewelers Mutual Group will be the presenting sponsor of Converge.

2024 CIBJO Congress to take place in November

The 2024 CIBJO Congress will take place from 2-4 November in Shanghai, China, with precongress meetings taking place on 31 October and 1 November.

CIBJO is the international jewellery confederation of national trade organisations. Its purpose is to encourage harmonisation, promote international co-operation in the jewellery industry and consider issues which concern the trade worldwide. CIBJO’s chief mission is to protect consumer confidence in the industry.

WFDB and Shanghai Diamond Bourse sign MOU to promote natural diamond industry

The World Federation of Diamond Bourses (WFDB), the association of the world’s major diamond bourses, and the Shanghai Diamond Exchange (SDE), the only designated platform for diamond import and export in China, have signed a Memorandum of Understanding (MOU) to promote the development of the diamond market in China.

The MOU follows meetings by WFDB leaders and Chinese government officials during the WFDB Presidents’ Meeting in Shanghai in March, where agreement was

reached to further the development of the Chinese diamond market through large-scale marketing campaigns and other initiatives.

The MOU seeks to further direct collaboration and synergy between the WFDB and the SDE, including events, campaigns and bilateral visits. According to the MOU, the WFDB will open a representative office within the China Diamond Centre and the SDE will focus on improving the development of the local diamond industry in greater China and on stimulating the growth of the diamond business.

MINING GIANT ANGLO AMERICAN WILL exit diamond, platinum and coal mining in a massive restructure designed to fend off a £34 billion (US$43 billion) bid from rival BHP. These actions represent the most radical changes to Anglo American in decades.

Anglo’s hand was forced by BHP’s approach – which it has twice rejected –but the move also responds to pressure from shareholders to shed less profitable businesses and focus on copper assets. Anglo American also owns three of the top 10 producing copper mines in South America, with ample room for growth. It is also a main producer of premium iron ore, which has historically accounted for the lion’s share of Anglo’s profit.

Anglo CEO, Duncan Wanblad, said that the changes would create a simplified company with a focus on its remaining “world-class assets” in copper, iron ore and fertilisers.

He added that the miner would be “extremely highly valued” by the end of 2025, when the restructure was complete, “to the extent that if anybody wants to buy us at that particular point, they’re going to have to pay an enormous amount of money for us”.

Anglo anticipates the restructuring replete, with the separation from De Beers and Amplats completed by the end of 2025. There has already been “inbound interest” in the firm’s coal assets, while Wanblad said there would be “people who’ll be interested in De Beers”.

Asked whether it was poor timing to be selling De Beers at the bottom of the diamond price cycle, he responded: “There are a number of potential pathways with De Beers, but it will be done for value.”

Anglo American owns 85% of the De Beers Group, the world’s leading diamond company. The remaining 15% is owned by the government of Botswana.

South African Mineral Resources and Energy Minister Gwede Mantashe said that he would prefer Anglo’s restructuring plan over a takeover by BHP. The plan was also welcomed by the Congress of SA Trade Unions.

Anglo American has announced a radical restructure in which it will sell or demerge De Beers and its 79%-owned Anglo American Platinum (Amplats).

Anglo to cut ties with De Beers, Amplats

De Beers Group comments on Anglo American strategy update

Following the announcement by Anglo American regarding its intention of exploring a range of options to separate the De Beers business, the De Beers Group remains fully focused on delivering its strategy and creating value in the interests of all its stakeholders.

“De Beers has led the diamond industry for more than a century. We have unparalleled expertise, outstanding assets across more than 20 countries, a unique sales model and an iconic brand, synonymous with diamonds. I’m confident

that we’ll remain the diamond leader for the next century,” said Al Cook, CEO of the De Beers Group.

“The announcement from Anglo American opens up new possibilities under new ownership. However, some things won’t change. We’ll continue to deliver value for all our stakeholders, including our partners in Botswana, South Africa, Namibia, Canada, Angola and other countries. In particular, we look forward to finalising our transformational agreement with the government of Botswana, which hold a 15% ownership interest in De Beers.”

Anglo’s hand was forced by BHP’s approach – which it has twice rejected – but the move also responds to pressure from shareholders to shed less profitable businesses and focus on copper assets.

Council of SA update Jewellery

Lorna Lloyd, CEO of the Jewellery Council of SA (JCSA), shares the latest developments from the council’s office

NAVIGATING THE REGULATORY LANDSCAPE of the jewellery industry in South Africa involves considerable administrative challenges due to stringent legislative requirements.

One crucial requirement in accordance with the Precious Metals Act is that companies engaged in manufacturing precious metal jewellery must obtain a Jeweller’s Permit. This permit, renewable every five years through the SA Diamonds and Precious Metals Regulator (SADPMR), authorises a company to purchase or receive semi-fabricated precious metals in any form, alter that form and dispose of any semi-fabricated precious metals in its possession.

To ensure compliance with regulatory requirements, the Jewellery Council is actively supporting its members in the application and renewal process for Jeweller’s Permits with the SADPMR. By offering assistance, the council facilitates adherence to the Precious Metals Act and members can navigate the regulatory landscape with confidence.

Another critical legislative requirement within the jewellery industry is adherence to the Domestic Reverse Charge (DRC) mechanism, which requires VAT vendors engaged in buying and selling gold and gold jewellery to revalidate themselves with SARS.

The Jewellery Council has assisted members with resources and training materials/ webinars to ensure they are compliant.

Recently, the Minister of Finance amended the regulations on DRC relating to valuable

metal to exclude suppliers of valuable metal containing less than 1% of gold in gross weight, or jewellery plated with gold where the gold is only present as a minor constituent, from the regulations.

Although there are advantages to the DRC, which is the unintended benefit of placing a VAT vendor in a better cash flow situation, it has also had inadvertent consequences for jewellers working in the insurance space.

The implementation of these regulations has led to a significant shift in payment dynamics, particularly regarding cash payouts in lieu of jewellery replacements by insurance companies. This shift not only undermines risk management practices, but disrupts the market by deterring individuals from purchasing jewellery replacements, ultimately threatening the sustainability of our industry.

space stand together and take proactive steps to safeguard the integrity of our insurance jewellers and mitigate the damage caused by these regulations.

Based on consultations and discussions with legal experts and industry stakeholders, our member has identified several actions that they believe must be taken to address this issue. He is proposing that a submission be drafted to National Treasury and SARS with the assistance of an advocate. We will report further on developments in this regard.

Despite efforts to engage with National Treasury and SARS on this matter, little progress has been made. A member of the Jewellery Council has proposed that industry members working in the insurance

Communication with members within the Jewellery Council is one of the most crucial responsibilities we have to ensure effective dissemination of important messages and updates. In addition to traditional e-mail communications, the inclusion of WhatsApp groups has emerged as a valuable communication tool. WhatsApp groups offer several benefits for communication within the council as they enable real-time messaging, allowing us to quickly convey urgent updates, announcements and reminders to each other.

They also encourage active participation and engagement from members, fostering a sense of community and collaboration.

As such, we have created WhatsApp groups for manufacturers and separate groups for retailers in the various regions.

The annual general meeting of the Jewellery Council will be taking place on 24 July. This meeting is important, as we will be conducting elections for key leadership positions, including the Chairperson, the board and the Executive Committee, for the next three years.

It is with both gratitude and sadness that we announce the departure of Chris van Rensburg from his role as Chairperson of the Jewellery Council. After serving four terms of office which were not consecutive, Chris will step down from his position, marking the end of an era for the council.

He has been an invaluable leader and advocate for the jewellery industry, dedicating twelve years of his time and expertise to furthering the interests of our members. His unwavering commitment, passion and vision have contributed significantly to the growth and success of the council during his tenure.

Throughout his leadership, Chris has been dedicated to advancing the goals and objectives of the council, championing

initiatives to promote innovation and sustainability within the industry. His efforts have helped strengthen the JCSA’s position as a trusted voice and representative body for all stakeholders in the jewellery sector.

Your participation in the AGM is crucial, as it allows you to have a voice in the governance of the Jewellery Council and help shape its future direction. We encourage all members to attend and participate actively in this process to get the most out of the relationship.

Enquiries about the council, its activities and how to become a part of a responsible jewellery community can be made by visiting our website at: www.jewellery.org.za. Alternatively, contact us on tel: (011) 484-5528 or e-mail: admin@jewellery.org.za.

JEM graduates shine

In May 2023, MetCon – one of South Africa’s most advanced refineries – in partnership with the Gauteng IDZ, introduced the Jewellery Excellence MasterClass (JEM), with the vision of equipping up-and-coming jewellers with the technical and business skills needed to take their creativity and businesses to the next level.

Based in the Jewellery Manufacturing Precinct in the OR Tambo Special Economic Zone, the four JEM graduates have spent the past year bringing their jewellery designs to life in a state-of-the-art workshop and attending multi-disciplinary MasterClasses. MetCon has further supported the initiative by outsourcing some of its manufacturing to these jewellers to aid the growth of their businesses.

“Our continent’s rich in precious minerals,

culture and jeweller talent,” says MetCon. “In the spirit of the Special Economic Zone, JEM encourages industry growth through the sharing of information and access to expertise, resources and support.”

On the evening of 9 May 2024, key industry stakeholders gathered at MetCon to celebrate the first graduates of the programme: Ayanda Zondi, Isabel Bothma, Kamogelo Phago and Mosiuoa Samuel Motitsoe.

MetCon MD Grant Crosse reflected on the performance of the group. “Is it possible that you guys manufactured over R22 million of product? That’s almost R2 million a month. Do you have any fingerprints left after such work!?” he asked.

“Everyone in this room shares a belief in the vast potential of SA’s jewellery industry. Yes, we have challenges to overcome, but what we also have is a continent rich in precious minerals and equally rich in culture, talent and creativity – the perfect ingredients for a jewellery industry to grow and thrive.”

A little over a year ago, MetCon – together with the Gauteng IDZ – introduced JEM, with the vision of equipping skilled up-and-coming jewellers with the technical and business skills needed to take their creativity and businesses to a global level. The vast majority of the R22 million of goods produced were delivered to the USA and the UK. “I’d certainly consider that to be proof of globally recognisable talent,” said Crosse.

Based in the SuperBlock building across the road from MetCon, the four graduates attended multi-disciplinary MasterClass training sessions with real, practical experience in commercial products. “The value of combining the two elements of practice and theory can’t be overstated. Like a diamond and engagement ring, the two are better together. Theory must accompany practical and proven experience to build talent that can deliver,” said Crosse.

“This is what the spirit of the Special

Economic Zone is all about: sharing and growing across buildings, across businesses and across cultures, while offering resources and support to benefit the greater industry. Let’s do more of it.”

Eddie Hazelhurst, JEM Programme Manager, expressed his appreciation to MetCon and the Gauteng IDZ for equipping the graduates with the tools and resources that enabled them to produce 1 390 units and over 17 kg of product for the global market.

“I’m also incredibly proud of these fellow jewellers: Sam, Ayanda, Isabel and Kamogelo. Each of you has brought unique talents and dedication to our craft,” he said. “Part of our journey included valuable business skills programmes facilitated through the Khulisane Academy, to which we extend our deepest gratitude for providing us with the knowledge and tools to navigate the business side of our industry.

“Collaboration will be our greatest asset. Together, we can overcome any challenge and seize every opportunity that comes our way.”

The vast majority of the R22 million of goods produced were delivered to the USA and the UK. I’d certainly consider that to be proof of globally recognisable talent.

JEM class of 2024

On 9 May, key industry stakeholders gathered at MetCon to celebrate the first Jewellery Excellence MasterClass (JEM) graduates. With the vision of equipping up-and-coming jewellers with the technical and business skills needed to take their creativity and businesses to the next level, this year’s graduates were Ayanda Zondi, Isabel Bothma, Kamogelo Phago and Mosiuoa Samuel Motitsoe.

Ayanda Zondi

Sweetwell Fine Jewellery

Ayanda Zondi, a core founder of Sweetwell Fine Jewellery, grew up in Pietermaritzburg, KwaZuluNatal. “I did my studies of jewellery design and manufacturing at the Durban University of Technology. I chose to study jewellery design because I like working with my hands and making adorable things,” he says.

“My experience in the jewellery industry started when I was doing my GDP at Pneuma Jewellers. That was when I was upgrading my skills in the two-year programme.”

Isabel Bothma

Isa B Jewellery Designs

Isabel Bothma is a creative. She loves design and is the CEO of Isa B Jewellery Designs, which she founded in 2020. She grew up in Machadodorp, Mpumalanga and is a proud Tshwane University of Technology (TUT) Jewellery Design and Manufacturing alumnus. After completing her studies at that institution in 2016, she did her GDP, during which she gained skills and knowledge in setting and engraving.

When she completed her GDP, she joined the Design @ 50 (a year-long CAD design programme) and obtained a certificate in professional CAD designing. She is also a mother of one and employs one person in her company.

Bothma chose jewellery design because of the curiosity that was kindled in her while admiring the beautiful HONEY Jewellery that her mother used to sell. While attending an open day at the TUT and seeing the metal melting into a wearable art, she felt sure that this was the start of her own journey

Tell us about your experience with JEM, what you enjoyed about it and how it has helped you.

My experience with JEM was very useful because it helped me take my skill to a professional level and know what’s expected of international jewellery quality. It also taught me how to run my business.

What are your dreams for the future of your business?

The most important thing for my business is to build up my brand for the future, to make it well known in SA and to expand internationally.

as a jewellery designer. She says she cannot imagine doing anything else.

Tell us about your experience with JEM, what you enjoyed about it and how it has helped you.

Having the opportunity to be part of JEM was an amazing experience. This MasterClass helped me enhance the quality of my products and taught me how to ensure that

quality goods are sent to stores. Also, the accredited business skills programme that forms part of it was great for my business knowledge. There were many things I’d missed when I was starting my business and I learnt a great deal through these classes and the teacher assisting us.

The exposure to gemstone setting, jewellery manufacturing processes and advanced finishing skills were also important things I experienced here and I believe they’ve elevated my skills in my career.

The course was very enjoyable and I highly recommend it.

What are your dreams for the future of your business?

My dream is to showcase my work beyond Africa, to the world. I’d also like to have an online store or a physical one here in Mzansi, where people from all over the world can buy my designs. In addition, I want Isa B to be more than just a jewellery brand and perhaps introduce more products in terms of accessories.

Kamogelo Phago

Luxity Fine Jewellery

Kamogelo Phago is a TUT alumnus who obtained a National Diploma and BTech in jewellery design and manufacturing between 2016 and 2019. She was born in Ga-Matlala, a small and vibrant village in Limpopo, where she was initially raised by her grandmother while her parents were based in Johannesburg, furthering their studies. She went to join them there at the age of seven.

Since her childhood, Phago has always enjoyed working with her hands. This culminated in her passion for drawing and an eagerness to explore and employ various techniques and tools to hone her skills as a creative and a goldsmith.

Her resilience and dedication are attested to by her work, which comprises distinct and stylish jewellery that give the wearer a sense of identity, worth, love and belonging. The pieces are sold through her company, Luxity Fine Jewellery, a distinguished South African company which she founded in December 2021. It specialises in the design, manufacturing and distribution of exquisite fine and commercial jewellery.

Although the company under Phago’s leadership is still in its infancy, it has already cemented its place in the jewellery and manufacturing industry, boasting a number of achievements.

Tell us about your experience with JEM, what you enjoyed about it and how it has helped you.

The Jewellery Excellence MasterClass played a significant role in my life, both personally and professionally, learning about platinum and pure gold and opening up the doors to skills improvement. I had the opportunity to refine my skills under the guidance of experienced mentors and learn advanced techniques in jewellery design and craftsmanship.

I gained a deeper understanding of gemmology, metalworking and design principles. The programme also provided business classes through the Khulisane Academy, giving us insights into business management and business development. It allowed me to connect with fellow artisans and industry professionals.

GoDaddy shares six tips for building a website to help your business be visible online and serve as a professional hub for your digital presence.

IN TODAY’S DIGITALLY CONNECTED WORLD, consumers tend to expect every business to be fully searchable for product information, location and operating hours, with an easily accessible website online. According to recent GoDaddy global research, 90% of small businesses surveyed said they felt that

digitalisation of their business was either very important or quite important to them.

With so much opportunity to share your business with people in your local area and around the world, it is likely many businesses are considering how to build a stronger online presence this year.

GoDaddy shares six tips for building a website to help your business be visible online and serve as a professional hub for your digital presence:

Consider the purpose of your website

It can be easy to get caught up in the design and functionality of what you know instead of what you would like consumers to know about your business. Take time to decide what the purpose of your website is and how you want viewers to engage with it. It is a good idea to be very clear on the front page of your website about what your business offers. For example, a restaurant owner might want to show their

location and menu images, while retailers might focus on showcasing their products and businesses selling experiences might consider videos and content as the best way of generating excitement before prompting a booking or enquiry.

Tell your story creatively

As a business-owner, consider what might set you apart from everyone else in a similar business. Perhaps it is the story behind why you do what you do. Videos, images and blog content could be a great way for prospect customers to get to know the brand personality behind your business, as well as its story. This can lead to deeper connections with your

target audiences which could positively impact the growth of your business and help set you apart from the competition.

Be clear about your call-to-action

One way you could generate leads from a website is by having a clear call-to-action. The type of call-to-action you use could vary, depending on the product or service your business offers. What would you like prospective and current customers to do on your website – buy a product, learn more about your business by reading your blog, know where to find you on a map, or see what your business does and how it might help them solve a problem? It is important that your call-to-action be prominent on your website and encourage your customers to take the next step.

Start simply, with lots of room for growth

It is easy to get excited about all the different website features and functions you could incorporate, but it is important to pay close attention to what you really need to get started. A simple website is both easy and cost-effective to build. It should make it easy for customers to navigate and come away with the information they wanted. Starting simply can also allow you to find time to focus on updating with fresh quality content, fast loading speeds and mobile optimisation.

Focus on your target audience

Have a clear idea about who your target audience is and focus on delivering an exceptional online experience for them. There are many things about your target audience that could influence the design, function and content on your website. Some key questions could include: how old are they? What activities do they like? How do

they communicate? How do they consume content? The answers to all these questions can help you create a website that resonates with your target audience and can effectively communicate how your products or services solve their problems or fit in with their lifestyle.

Choose the right website tools and hosting provider

Once you have determined the strategy for your website, the next step is to build it. The good news is that today there are tech tools that help make it quick and easy to build and maintain a website without having a technical degree. GoDaddy Website Builder, for example, offers templates, images, features text and other information to help you build a professional website for your business. You can also choose to have your website hosted by the same provider where you have registered your domain, for a more integrated experience.

Creating a home for your business on the Internet can be a way to help you grow it and remain engaged with your customers for many years to come – and now might be the best time to get started.

About the Merensky Reef

The Bushveld Igneous Complex (BIC) in the North West, Limpopo, Gauteng and Mpumalanga – together with an underlying layer, the Upper Group 2 Reef – holds over 70% of the world’s known reserves of platinum, palladium, rhodium, ruthenium, iridium and osmium.

The Bushveld Complex chromitites were first reported by Hall and Humphrey in 1908. The initial recovery of platinum in SA took place on several of the large East Rand gold mines and the first separate platinum mine was a short-lived venture near Naboomspruit that worked very patchy quartz reefs. The discovery of the Bushveld Igneous Complex deposits was made in 1924 by a Lydenburg district farmer, AF Lombaard. It was recorded to be approximately 80 km in length. This was an alluvial deposit, but its importance was recognised by Merensky, whose prospecting work discovered the primary source in the Bushveld Igneous Complex and traced it for several hundred kilometres by 1930.

DIAMOND RELFECTIONS

The Lengthy Vertical Journey of Superdeep Diamonds

Editor: Evan M. Smith

Aside from their dazzling gem appeal, one thing that makes diamonds so interesting is the great depths below the earth’s surface at which they form. The majority of diamonds mined as gemstones were formed in the base of ancient thick regions of continents, at a depth of about 150–200 km. This is already an incredible depth compared to virtually all the other rocks and minerals around us at the earth’s surface. Even more extreme, however, are superdeep or sublithospheric diamonds, which originate from a depth of approximately 300–800 km (Shirey et al., 2024). With these superdeep origins in mind, how is it that they can be found at the earth’s surface?

Exactly how superdeep diamonds make their way up to the surface has long remained a curiosity. It has been considered that kimberlites and related mantlesource volcanic eruptions might simply originate from comparable depths as superdeep diamonds, providing a single mechanism to carry superdeep diamonds all the way to the surface (Giuliani and Pearson, 2019). The depth of kimberlite formation is still unclear, however, and a shallower kimberlite origin from just below the continental lithosphere, no deeper than 300 km in the asthenosphere, appears more likely (Giuliani et al., 2023).

Such a shallow origin is supported by a recent model that links the timing and placement of kimberlites with convective instabilities or eddy currents associated with continental rifting (Gernon et al., 2023). As illustrated in figure 1, this model places the origin of kimberlites far closer to the surface than superdeep diamonds. An intermediate transport mechanism likely brings them up closer to the base of the lithosphere to be sampled by kimberlites alongside shallower lithospheric diamonds.

Several potential intermediate transport mechanisms have been proposed. These include mantle convection (Davies et al., 2004; Harte, 2010), localized buoyancy of the mantle rocks associated with diamond formation (Smith et al., 2018), upward-percolating melts (Walter et al., 2022), and— perhaps the most widely accepted—mantle plumes, which are hot columns of rock rising through the mantle due to their lower relative density (Stachel et al., 2000; Tappert et al., 2005; Bulanova et al., 2010; Walter et al., 2011; Harte and Richardson, 2012). The timing of this journey with respect to diamond formation and later kimberlite eruption has also

been unclear. There may be an intermediate period of storage in the upper mantle (Stachel et al., 2000). A recent study by Timmerman et al. (2023) reporting superdeep diamond ages has shed new light on their lengthy vertical journey.

A Primer on Superdeep Diamonds

There are multiple ways in which diamonds can form in the mantle. Diamond growth can occur in different geologic settings and involve different types of host rocks and carbonbearing fluids (Shirey and Shigley, 2013). Diamonds in the mantle can be broken down into two principal geologic settings or places where they grow: the lithospheric mantle and the sublithospheric mantle (figure 1). Further subdivisions are possible, but for simplicity we will only consider these two overarching groups. Note that here we are strictly speaking about mantle-derived diamonds found in kimberlites and related rocks or their eroded components. These are the kinds of diamonds mined as gemstones, which excludes diamonds from sources such as ultra-high-pressure metamorphic terranes, meteorites, impact sites, and ophiolites.

Diamonds from the lithospheric mantle crystallize in the base of old and thick regions of continental lithosphere (figure 1). These are the most common kinds of diamonds.

The second major geologic setting is the sublithospheric mantle, below the rigid lithospheric plates that make up the earth’s surface. Diamonds formed here are termed sublithospheric or superdeep diamonds. Superdeep diamonds make up an estimated 2% of diamonds mined globally, although the exact proportions are not well constrained and can vary greatly by deposit (Stachel et al., 2022).

When we encounter diamonds at the surface, they have been swept up into kimberlites or related mantle-derived igneous rocks. Lithospheric and superdeep diamond populations often mix together, as depicted in figure 1. Mineral inclusions provide a method for identifying these different kinds of diamonds because the mineralogy of mantle rocks changes with depth. When diamonds contain one or more inclusions that could only have been trapped within the sublithospheric mantle, this is conclusive evidence that the host diamond is superdeep. Good examples are ring-woodite (Pearson et al., 2014) or coexisting inclusion pairs of ferropericlase and bridgmanite (found as enstatite) (Stachel et al., 2005).

Superdeep diamonds have been studied with fervor since their discovery unfolded in the mid-1980s (Moore and Gurney, 1985; Scott Smith et al., 1984). A brief history of superdeep diamond research is recounted by Shirey et al. (2024). These crystals obtained from the deep have captivated scientists because they

provide the only well-preserved samples of the sublithospheric mantle, making them uniquely suited to study the composition, dynamics, and evolution of the earth’s interior.

More recently, the breadth of superdeep diamonds has increased substantially as two varieties of high-quality gem diamonds were found to be sublithospheric. These are the nitrogen-poor, large, high-clarity diamonds subsequently named CLIPPIR diamonds and type IIb diamonds, which can have beautiful blue colors resulting from their boron content (Smith et al., 2016, 2017, 2018). Both of these newly recognized superdeep varieties, as well as many previously documented diamonds from the Juína region of Brazil and other global localities, have an association with subducted slabs of oceanic lithosphere (Walter et al., 2011; Smith et al., 2021; Regier et al., 2023). Subduction is a major geological process capable of recycling material such as carbon and water from the surface down into the mantle. The fact that superdeep diamonds offer insight into subduction processes makes them all the more valuable for learning about the geological evolution of our planet. For further background on superdeep diamonds, see reviews by Harte (2010), Harte and Hudson (2013), Kaminsky (2012), Shirey et al. (2024), Smith and Nestola (2021), Stachel et al. (2005), and Walter et al. (2022).

Ages of Superdeep Diamonds Rock and mineral ages help unravel sequences of geologic events.

For diamonds, however, measuring an age of crystallization is often difficult and sometimes impossible because it relies on radiometric dating of inclusions. In order to obtain a reliable age, it is essential to obtain a diamond with the right kinds of inclusions to be analyzed for radiogenic isotopes. Radioactive isotopes decay at a prescribed rate and can be used as a sort of internal clock to date inclusions. Generally, the age of an inclusion is assumed to correspond to the age of its entrapment in the diamond host, and therefore the age of diamond growth. Overviews of diamond dating were contributed by Smit and Shirey (2019) and Smit et al. (2022).

Finding superdeep diamonds with the right kinds of inclusions has been challenging, in part because of their rarity and the often small sizes of the inclusions (Shirey et al., 2024). There are fewer diamonds and fewer inclusions to choose from. Another challenge stems from the fact that isotopic measurements need to be representative of the entire inclusion. This is not a problem if an inclusion is homogeneous, but if it is unmixed or separated into multiple phases, the entire inclusion needs to be sampled in a bulk analysis. The latter is typical for superdeep diamonds because their inclusions tend to be retrograded or unmixed in texturally complex mineral assemblages and surrounded by large fractures into which parts of the inclusion may spread. In some cases the large fractures extend to the diamond’s exterior, which effectively opens the inclusion system to leakage or contamination and

compromises the inclusion entirely. Some limited preliminary dating work suggested generally young ages compared to lithospheric diamonds (Bulanova et al., 2010; Harte and Richardson, 2012). Despite these difficulties, a recent study by Timmerman et al. (2023) has found coherent ages from four isotope systems (Rb-Sr, Sm-Nd, U-Pb, and Re-Os) applied to a suite of 11 diamonds from the Juína area of Brazil and two from Kankan, Guinea. Both localities are well-known occurrences for superdeep diamonds. The analyzed inclusions were calcium silicates, interpreted as former calcium silicate perovskite, as well as one example of iron sulfide. Taking all the data together gives overlapping ages of approximately 450 to 650 million years old (Timmerman et al., 2023). Although this range may seem imprecise, it is a remarkable result given the agreement across multiple isotope systems. Establishing this two-locality superdeep diamond age is a big piece of the puzzle of how the diamonds reached the surface.

Putting the Pieces Together

Ages help put the diamonds into a broader geological context. First, we can compare the 450–650 Ma (million years ago) ages of Juína and Kankan superdeep diamonds with the Cretaceous ages of their host kimberlite eruptions (the Cretaceous period spanned 145–66 Ma). Some of the Juína diamonds were from the Juína-5 and Collier-4 kimberlites, but the remaining Juína and Kankan diamonds studied by Timmerman et al. were from alluvial deposits, eroded from nearby kimberlites. Therefore, the kimberlite eruption age for all the samples was conservatively bracketed as Cretaceous (Timmerman et al., 2023).

The fact that these diamonds formed 450–650 Ma and later arrived at the surface in kimberlites around 145–66 Ma means the diamonds must have spent more than 300 million years in storage somewhere in the mantle. One scenario could be that the diamonds were formed and stored deep in the sublithospheric mantle, perhaps drifting with mantle convection currents. Later, in the Cretaceous, random packages of diamonds of coincidentally similar ages were carried upward by unidentified mechanisms and sampled by kimberlites at Juína and Kankan. However, this scenario of deep and mobile storage does not fit well with the spatial context of these two localities, considering past tectonic plate movements.

At the time of diamond formation, Juína and Kankan, now separated by the Atlantic Ocean, were actually close neighbors in the supercontinent Gondwana. Given that these localities were adjacent, Timmerman et al. suggest that the similar age of the diamonds is not merely a coincidence but an indication that they formed in broadly the same sublithospheric setting.

Subducting oceanic lithosphere around Gondwana’s edges (figure 2, step 1) would have made the sublithospheric mantle beneath Gondwana an ideal place for superdeep diamond growth. It is plausible that the studied diamonds formed in the sublithospheric mantle directly beneath the ancient neighboring Juína and Kankan sources (figure 2, step 2).

Since 450 Ma, the Juína and Kankan locations migrated about 6,500 km as the tectonic plates drifted. At the beginning of the Cretaceous, Juína and Kankan separated as the Atlantic Ocean spread open (Timmerman et al., 2023). The notion that subsequent kimberlite eruptions contained those ancient subGondwanan superdeep diamonds suggests that the diamonds were somehow pinned to the overlying continental blocks and were able to migrate with them. Timmerman et al. argue that the diamonds ascended in packages of buoyant, low-density rock shortly following their growth and that these diamond-studded rocks adhered to the underside of the continental lithosphere (figure 2, step 3). Melt-depleted metaperidotitic rock in the subducting slab could heat up near the top of the lower mantle (660 km), becoming less dense than the surrounding mantle and tearing apart to shed buoyant blobs of rock.

It is not an obvious answer that emerges, but with the above lines of reasoning from Timmerman et al. we arrive at the multistage model shown in figure 2. Knowing the diamond ages and being able to put them into the context of subduction and plate movements suggests steps 1 through 4 are successive and related. Subduction beneath Gondwana (step 1) creates a favorable setting for diamond growth (step 2). Portions of the subducted slab heat up and become buoyant, ascending through the mantle (step 3) and adhering to the bottom of the overlying continental lithosphere (step 4). These steps likely occurred within 450–650 Ma, after which the diamonds spent more than 300 million years in storage at the base of the continental lithosphere as the plates drifted across the earth’s surface. At the start of the Cretaceous, continental rifting separates the continental blocks as the Atlantic Ocean opens up (step 5). Mantle instabilities caused by rifting lead to kimberlite eruptions within tens of millions of years (Gernon et al., 2023) and the dormant superdeep diamonds are finally swept up to the surface (step 6).

The model outlined in figure 2, with consecutive processes of diamond formation and ascent that are both linked to the subducted slab, could apply to other superdeep diamonds, not just those at Juína and Kankan. An intermediate period of storage in the upper mantle has been proposed previously based on the textures of unmixed or retrograded mineral inclusions (Stachel et al., 2000). For example, some superdeep diamonds

contain two-phase inclusions of breyite (CaSiO3) and perovskite (CaTiO3), which are interpreted as unmixed from an original single-phase Ca(Si,Ti)O3-perovskite (figure 3). Unmixing of these two phases would have occurred at a depth shallower than about 300 km, consistent with a period of shallow mantle storage prior to kimberlite eruption (e.g., following step 4 in figure 2). These and other types of inclusions, such as majoritic garnets, show consistent evidence of re-equilibration that could occur during storage in the upper mantle (Timmerman et al., 2023).

Even beyond mineral inclusions, CLIPPIR and type IIb superdeep diamonds have textural evidence consistent with a period of storage in the mantle. These diamonds contain ubiquitous

dislocation networks, seen in cathodoluminescence and deepUV (<230 nm) imaging (figure 4) (Smith et al., 2017, 2018; Regier et al., 2023). Plastic deformation generates the dislocations, but their movement and reorganization into network patterns requires a period of recovery at high temperatures (Hanley et al., 1977). If these kinds of superdeep diamonds also ascend with buoyant slab-derived rocks and adhere to the continental base, this period of quiescent storage could provide the right conditions for dislocation network formation.

irrelevant in assessing the value of a potential diamond deposit. But the recognition that some of the highest-quality and most valuable type IIa and type IIb diamonds are superdeep is changing this perception (Smith et al., 2016, 2017, 2018). Now we can recognize that some diamond mines, such as Letšeng (Lesotho), Cullinan (South Africa), and Karowe (Botswana), derive a major portion of their revenue from superdeep diamonds. The development of tools for exploration and mining that can specifically target superdeep diamonds would be advantageous. Currently, lithospheric mantle indicator minerals such as eclogitic and chromium-pyrope garnets are

used as a proxy for diamond potential, but this tool is blind to superdeep diamonds. Developing a better understanding of how superdeep diamonds reach the surface does not necessarily reveal a simple solution for their exploration, but it might help geologists look in the right direction. It appears likely that superdeep diamonds ascend in packages of buoyant rock and are stored in the upper mantle, which could be an important clue. Host rocks in this intermediate setting might shed distinct indicator minerals or geochemical signatures into erupting kimberlites that are more widespread and easier to detect than the superdeep diamonds themselves.

How do you reward a multigenerational workforce?

Managing expectations in the workplace is challenging, particularly when faced with the career aspirations of four different generations in one organisation, or even one team.

EMPLOYEES ARE LIVING LONGER AND want to retire later, which means more and more organisations find themselves with a generation mix from Baby Boomers to Gen Z. Each, depending on their life stage, will have different needs, wants, views and expectations about remuneration, benefits and their career.

Team composition

It is key to understand the generational composition of one’s team, says Deon Smit, Master Reward Specialist and Executive Committee member at the South African Reward Association (SARA).

“Generational theory can be quite broad and one must guard against stereotyping, as each generation brings with it further diversification, whether it’s marital status, culture, religion or job level,” he explains.

Smit says it is important to structure the different elements of reward to ensure flexibility in the system to cater for diverse aspirations and needs. “This process should be transparent and information-based,” he adds.

Baby Boomers (employees aged 59-65) currently make up around 13% of the workforce in SA. While Gen X, aged 45-59, represents 32%, Gen Y (Millennials), aged 29-45, also

represents 32% and Gen Z (aged 18-29) could be up to 23% of the workforce already.

The key when having such a diverse workplace is flexibility, stresses Smit. A one-size-fitsall approach is bound to create unhappiness and the risk of losing talent then becomes a greater reality.

Flexibility

A reward programme should be as flexible as possible, without being administratively onerous. This is especially the case for benefits such as medical cover and retirement funds. “Understand the trends and play to the strengths of each generation,” advises Smit.

Baby Boomers, for example, may be motivated by prestige and position. These employees are passionate about participation in the workplace and they can be invaluable mentors.

However, Gen X employees want to

Baby Boomers (employees aged 59-65) currently make up around 13% of the workforce in SA. While Gen X, aged 45-59, represents 32%, Gen Y (Millennials), aged 29-45, also represents 32% and Gen Z (aged 18-29) could be up to 23% of the workforce already.

work to live, not live to work. They are entrepreneurial, sometimes sceptical of corporations and dislike close supervision. Millennials prefer a more open and transparent work relationship, are less loyal to organisations, enjoy collaboration and teamwork, and are less willing to sacrifice personal time for their career.

Gen Z employees are not always motivated by status or money. They are far less willing to sacrifice personal time for their career and are certainly far less loyal to organisations than previous generations. They thrive on diversity, change and making the world a better place. The newest entrants to the workforce, Gen Z employees are very tech-savvy, and understand and navigate social media with great comfort. They want to be in control and they do not hesitate to challenge the status quo

The reward framework

The strategic reward framework needs to include a flexible remuneration and benefit structure, opportunity for work-life balance, growth opportunities and career development for all employees of each generation. Talent retention becomes far easier when a manager understands that a Gen Z employee may not be motivated by the same things as previous generations. They have little brand loyalty and will not tolerate a workplace that is not technologically advanced, whereas a Millennial employee wants a career plan and thrives on being challenged, developed and mentored.

Smit says one way of measuring why different generations are staying in one’s organisation is by having regular “stay interviews”. This offers great opportunities for managers to enhance their remuneration, benefits and reward programmes to create greater retention of key skills and talent.

Tudor 2024 watches announced

Tudor has revealed its watches for 2024, which include new iterations of the Black Bay, Black Bay 58, an all-new, Master Chronometer-certified Black Bay 58 GMT and a Clair de Rose line with new brand-signature blue dials.

REGISTERED IN 1926 BY HANS WILSDORF, founder of Rolex, the brand remains a sister company to Rolex; both companies are owned by the Hans Wilsdorf Foundation. Tudor was initially known for watches produced for military and professional divers. From the 1960s to the 1980s, several navies issued Tudor Submariners to their divers, including the US Navy SEALs and the French Marine Nationale.

The brand has revealed its new watches for 2024, which confirm that it is on a high wave and is committed to meeting collectors’ expectations. The latest models include a GMT Black Bay 58, a renovated and refined Black Bay and a full-gold Black Bay.

• The newest iteration of the Black Bay in monochrome

This model features evolved design elements and a “T-fit” clasp and is Master Chronometer-certified by METAS.

This emblematic design is another example of Tudor’s expert command of one of the industry’s most demanding standards in terms of chronometry and resistance to magnetic fields.

• A bold, new version of its popular model, the Black Bay 58, now in 18ct yellow gold

With an open case-back, Manufacture Calibre and now a solid gold bracelet, complete with “T-fit” clasp, the Black Bay 58 is also the first Tudor divers’ watch to be made in 18ct solid yellow gold. It now comes with a matching all-satin-finished 18ct yellow gold bracelet to boot.

• The all-new, Master Chronometercertified Black Bay 58 GMT.

With a 39 mm diameter case and a bidirectional bezel festooned with warm hues reminiscent of the golden age of air travel,

this entirely new model is evocative of an era when the novelty of jet-setting across time zones was matched by glamorous and elegant style. It is fitted with Tudor’s new mid-size GMT Manufacture Calibre, paired with warm hues of burgundy, black and gilt on the bezel. The universally appealing case of the Black Bay 58 has become the model’s calling card and it now comes in GMT form.

• Tudor revisits the feminine Clair de Rose line with the addition of new, brand-signature blue dials

Available exclusively in stainless steel with mechanical movements, these new configurations come in three sizes, each with two designs.

In 2024, the family gets a brand-new “Tudor Blue” dial. In a classic, refined and timeless spirit, it uses the brand’s historic aesthetic codes without straying from the gentle curves of its middle case and its striking winding crown, which on this model is set with a blue spinel cabochon. Available in three sizes, 26 mm, 30 mm and 34 mm in diameter, it presents opaline and “Tudor Blue” dials with delicate decorations in relief, punctuated with Roman numerals or diamonds.

The new timepieces play with contrasts to achieve a harmonious balance of functionality and aesthetics, performance and preciousness, tradition and innovation.
