Gemstone Testing and Identification

Gemstone evaluation may involve refractive index (RI), specific gravity (SG), magnification, colour observation, and other suitable gemmological tests.

For reliable identification, use appropriate instruments and consult a qualified gemmologist or recognised gem laboratory when necessary. A photograph or single measurement cannot conclusively identify every gemstone or prove its geographic origin.
