Gemological Institute of America (GIA) recently encountered a number of stones that were submitted for updated reports or verification services that did not match the GIA report submitted with them. The newly-submitted stones were either laboratory-grown diamonds or treated natural diamonds, falsely inscribed with GIA report numbers.<\/p>\n\n\n\n
Consistent with GIA\u2019s mission to protect consumers and ensure their trust in gems and jewelry, the Institute overwrites the counterfeit inscription with Xs; issues a new, accurate report; and inscribes the newly-submitted stone with the number of the new report and, when appropriate, the phrase \u2018Laboratory-Grown.\u2019<\/p>\n\n\n\n
The newly-submitted stones had the following commonalities: (1) the weights and grading parameters of the original and newly-submitted diamonds were close to each other; and (2) the newly-submitted diamonds were inscribed with counterfeit inscriptions of the original GIA report number.<\/p>\n\n\n\n
In a recent example, the report that accompanied a diamond submitted for an update was for a 1.50362 carat, VVS2, E, type I natural diamond with an excellent cut grade. The newly-submitted stone with a counterfeit inscription was a man-made diamond, 1.51212 carat, VVS2, D, type IIa with a very good cut grade. It is clear that these are two different diamonds.<\/p>\n\n\n\n
\u201cThese instances of attempted fraud highlight why it is important, especially in any transaction where the buyer does not have a trusted relationship with the seller, to have the diamond grading report updated prior to completing a purchase,\u201d GIA said.<\/p>\n","protected":false},"excerpt":{"rendered":"
