Description:


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.

Fable brand Chelsea Filter with:

1. With Excellent Spectralite Color Filter.

2. Fastness and Non-lackness.

3. With Leather Package.


Applications: Gemological Laboratory, Gemology school, Jewelry industrial
