The Gemological Institute of America (GIA) begins offering geographic origin determinations on its Emerald Identification Reports effective December 1, 2006.
Shane McClure, director of Gem Identification in GIA's California Laboratory, said the service expansion is a pivotal step for GIA. "The Institute has always held that the intrinsic quality of an emerald was the most important factor in determining its market value."
"While we staunchly believe that the quality of gem material will always be of primary importance, we recognize that the marketplace perceives the country of origin of an emerald to be of added value, and is therefore a factor in its valuation," said McClure.
