Gemological Institute of America (GIA) reported seeing an increase in the number of laboratory-grown diamonds (LGDs) submitted for update or verification services with counterfeit inscriptions referencing GIA natural diamond reports. The majority of the newly-submitted LGDs have higher clarities and their measurements and weights were almost identical to the GIA reports referenced by the counterfeit inscriptions.<\/p>\n\n\n\n
\u201cThis unfortunate situation demonstrates 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 before completing a purchase,\u201d said Tom Moses, GIA Executive Vice President and Chief Laboratory and Research Officer.<\/p>\n\n\n\n
This most recent example, submitted in Antwerp, of a laboratory-grown diamond with a counterfeit inscription highlights how close the man-made stone’s measurements are to the information on the original report. The report that accompanied the stone submitted for an update was for a 3.078 carat, 9.33 – 9.38 x 5.74 mm, Internally Flawless, G, natural diamond with triple excellent make. The newly-submitted stone was a 3.075 carat laboratory-grown diamond measuring 9.39 – 9.41 x 5.76 mm, VVS2, H, with a triple excellent make. At first glance, the natural and laboratory-grown diamonds described above are almost identical; the measurements were within just hundredths of millimeters of each other.<\/p>\n\n\n\n
When GIA encounters these cases, the institute overwrites the counterfeit inscription, inscribes a newly issued report number and “Laboratory-Grown” on the girdle of the diamond. In February 2021, GIA reported a similar incident of a number of treated natural diamonds submitted for update or verification services with counterfeit report number inscriptions.<\/p>\n","protected":false},"excerpt":{"rendered":"
