The Gemological Institute of America (GIA) has reported that ts New York City lab received a package with just one natural stone and more than 1,000 undisclosed pieces of lab-grown melee.
According to IDEX Online, the package, which was sent to the GIA lab for analysis, contained 1,102 melee diamonds with a total weight of 9.67 carats. There was no disclosure of the stones’ origin in the parcel. Among the 1,102 stones, 1,093 were referred by the lab for further testing. The GIA then found that “1,092 of them were HPHT synthetics grown, one was natural, and nine were outside of the GIA’s screening criteria”.
The GIA commented: “It is interesting to note that only one natural was found in this parcel of melee. This has been the largest percentage of undisclosed synthetic melee that GIA has seen”.
