2.Chelsea Filter
:
An essential device in 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. Just hold the filter close to the eye with the stone or stones (for a number of stones can be examined at one time) 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, soude Emeralds) retain a green appearance. A helpful tool in identifying certain red, blue and green stones.
Specifications:
- Filter Diameter: 30mm
- Body: Made of heavy metal
- Lens: Optic lens, not plastic lens like some other similar priced ruby filters from other sellers.

This Chelsea filter and Ruby filter bundle is so handy!
I do not know where I would be if I had a poorly made Chelsea filter, I am very glad to have this one. The Ruby filter is also a useful tool, both help me to make sure that the jewelry I purchase and sell has legitimate gems. These are an amazing quality for the affordable price.
