This kit, if used properly will allow you to identify about 85% of all precious gemstones, using three simple tools - Chelsea Filter, Dichroscope and Jewelers Loupe. This kit includes the following items: Chelsea Filter Of the many tools introduced to jewelers in the past few decades, the Chelsea filter has become one of the most popular. Originally used to differentiate genuine emeralds from other similarly colored stones such as tourmaline and peridot, the Chelsea filter is now used, often in conjunction with other tools such as the loupe or dichroscope to be able to identify mostly any gemstone. Since technology for creating synthetic gemstones has vastly improved in recent times, checking stones with the Chelsea filter alone is n longer considered sufficient. Dichroscope The dichroscope is another popular tool, which, like the Chelsea filter, is considered invaluable for distinguishing certain stones from similar gems. It can only be used on stones that are transparent, and are able to transmit light. It is used to differentiate between and identify stones of the similar colors. When looking through the dichroscope, the user should see two squares/rectangles, side by side. When viewing a stone, the user will see that it is either a single or a double refracting stone. 10x triplet jewelers loupe in black housing Used to detect chips, cracks, scratches, sharpness of edges, symmetry in cutting, presence and types of flaws.

Description
This gemological tool is helpful for identifying certain red, blue and green gemstones. It is used to determine whether a gemstone is natural or synthetic and can also be used for detecting Synthetic Blue Spinel as well as for detecting dyes in certain gemstones. The Chelsea Filter is a popular Gemological Dichromatic Filter that was originally devised by Anderson and Payne in 1934 at the Gem Testing Laboratory of the London Chamber of Commerce. The filter was devised with the collaboration of gemology students of the Chelsea College of Science and Technology. As this filter allowed transmission of both deep red wavelengths around 690 nm and yellow-green wavelengths, around 570 nm, that matched an Emerald's emission and absorption characteristics, it was initially recommended to assist the discrimination between natural emerald and its simulants such as Green Glass, Tourmaline, Peridot, etc. This discrimination was possible because Chromium - containing Iron - and Vanadium-Free Emeralds emitted a red fluorescence when illuminated by white light that had a content of ultraviolet wavelengths.3.

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 certain red, blue and green stones. Chelsea filters are primarily used for spotting fakes added to colored stone parcels and mixed in jewelry, and to differentiate emerald from emerald look-alikes, it is also useful for checking aquamarine and sapphires.

In rare cases certain emeralds, most notably from South Africa, may not show any pinkish color at all.

Feature
mini typeChelsea Flter
It's helpful with identifying certain red,blue and green stones
Description
While it was originally intended to rapidly differentiate between genuine Emeralds and the pastes and doublets which resemble them, it also is a valuable aid in identifying other colored stones, as well. Designed to transmit only deep red and yellow-green light, and the best results are obtained when stones are examined under a strong electric light. Testing stones is very simple, just hold the filter close to the eye with the stone or stones (stones can be examined simultaneously) receiving as much light as possible. Under these conditions, Emeralds (absorbing in the yellow green) usually appear distinctly red or pinkish in colour, the actual tint varying from merely pinkish in the case of pale stones, to a rich almost ruby red for better coloured specimens. On the other hand, most imitations of the genuine stone (pastes, doublets, soud?Emeralds) retain a green appearance. Chelsea is definitely a helpful tool in identifying certain red, blue and green stones10. Ade Advanced Optics Chelsea Filter for Gem Testing
