The Gemological Institute of America (GIA) has introduced origin reporting for alexandrite, adding the gem to its Colored Stone Identification & Origin Report services for ruby, sapphire, emerald, Paraíba tourmaline, and red spinel.
GIA’s reports describe if a stone is natural or laboratory-grown, as well as identify its type and treatments. Further, they offer an opinion on the gem’s geographic origin, as well as a description of its characteristics (i.e. cut, shape, weight, measurement, and colour).
“Offering an alexandrite Identification & Origin Report continues GIA’s mission to bring our research-based laboratory services to our clients,” said Shane McClure, global director of coloured stone services. “This service ultimately benefits the gem- and jewellery-buying public by providing reliable reports.”
