FABLE Chelsea Filter FCF-25

Chelsea color filter is a special optical lens that transmits only red and some yellow-green light and absorbs other colors. Chelsea filter is an auxiliary identification instrument, mainly composed of color filters with strong selective absorption, which allow some wavelengths of light to pass through and absorb the remaining visible light. Different gemstones have different selective absorption and different residual colors, so the reactions under the color filter are also different. The purpose of distinguishing gemstones can be achieved by using the different reactions of gemstones under the color filter. The Chelsea filter only allows deep red and yellow-green light...

Emerald Filter Chelsea Filter

Model: FCF-25

The renowned CHELSEA FILTER is a must have for identifying colored stones. 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.

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