Gemological Testing

Very often, people will inherit, buy, or find gems and jewelry without knowing exactly what they are. To help with those situations, we offer our gemological identification service. 

We utilize advanced technology, including the G.I.A. Professional  Microscope with Leica optics, which is the same microscope used at G.I.A. to grade some of the world's finest diamonds. 

Identification is performed by a Graduate Gemologist, trained in-residence at the Gemological Institute of America World Headquarters in Carlsbad, California. Graduate Gemologists are trained experts in the field of gem identification and are able to perform a variety of scientific tests in order to determine the identity of a potential gem.
