Chelsea Filter

Ideal Equipment for Stones

ACMAS TECHNOCRACY PVT. LTD. www.measuring-meters.com | www.acmasindia.com | www.scientificlaboratoryequipments.com

Detailed Explanation : Our Chelsea Filter is designed to transmit only deep red and yellow-green light ( best obtained under strong electric light) . Just hold the filter close to your eye and look at the stones. Multiple stones can be viewed at once. It is helpful with identifying a few red gems and certain blue and green stones. Chelsea Filter can filter out mixed-in jewelry and differentiate emerald from emerald look alikes. It is also useful for checking aquamarine and sapphires.

With the filter, emeralds usually appear distinctly red or pinkish in color, while most imitations remain green. In rare cases certain emeralds, mostnotably from South Africa, may not show any pinkish color at all. A synthetic emerald will react the same as a genuine one.

Rubies ( both genuine and synthetic) appear brilliant red under the filter. Synthetic blue spinel appear yellow-orange or pink while aquamarine and sapphires appear green or green-grey This Chelsea color filter has a glass filter. This gives better clarity, reduces distortion and provides better protection from humidity.

The Chelsea Filter is a combination of two gelatin filters that transmit only deep red and yellow/ green light. As Emeralds transmit light in the deep red spectrum but absorb light in the yellow/ green spectrum, this combination is the most practical. It is a useful tool to distinguish natural emerald and natural green beryl, as well as most green and blue gems.
