CHELSEA / RUBY FILTER FOR GEM TESTING
A valuable instrument for those travelling to Madagascar / Mozambique / Tanzania for Gem Hunting. This is an essential device in identifying colored stones in the field.
This Chelsea color filter has a glass filter which gives better clarity, reduces distortion and provide better protection from humidity.
Emeralds under Chalsea Filter, most notably from South Africa, may not show any pinkish color at all. A synthetic Emerald will re-act the same as a genuine one. Rubies (both genuine and synthetic) appear brilliant red under the filter. Synthetic blue spinel appears yellow-orange or pink while aquamarine and sapphires appear green or green-grey.
•Filter Diameter: 20mm
•Body: Made of metal
•Leather Carry Pouch
