Gem-A Chelsea ® Colour Filter

Developed originally to distinguish emeralds from imitations and doublets, this filter helps narrow down the possibilities when identifying certain green, red and blue stones.

When seen through the filter, many natural and synthetic emeralds look red or pink, while other green stones look green.

This instrument helps detect dyes in certain gems, such as dyed green and blue chalcedony
