This filter is designed to transmit only deep red and yellow-green light (best obtained under strong electric light). 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.


Chelseafilters 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 fromSouth Africa, may not show any pinkish color at all. A synthetic emerald will react the same as a genuine one.


Chelseafilter is useful for separate emeralds from imitations, viewing through the filter, natural and synthetic emerals look red, or pink, other green stones stil look green ,also helps detecting dyes in the certain gems, such as dyed jade green, etc.
