Lab Debuts Rough-to-Polished Gem Tracker

RAPAPORT... The Swiss Gemmological Institute (SSEF) has launched aservice for linking polished gemstones to their original rough, it saidTuesday. GemTrack creates a fingerprint that documents the stone'sjourney from mine to market, based on analyses of the stone's crystallographic,structural, chemical and microscopic features. "Given the growing demand for provenance and traceability inour industry, we felt that SSEF can provide a truly independent gemologicaldocumentation for a gem on its journey from the rough to cut state, and even toits being set in jewelry," said Michael Krzemnicki, director of SSEF.
