Product Description
Emerald Color Filter

Emerald Color Filter

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.

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.
