This just dropped into my inbox. Although it's to do with diamonds, I know that we, in the CS forum, are very keen to know what's happening with labs and treatments.
Rapaport Trade Alert
May 12, 2015 … The Gemological Institute of America (GIA) has issued a laboratory alert recalling 424 diamond grading reports. The diamonds were treated with a process that temporarily improved their color by up to three grades. A full list of the grading report numbers and the companies that submitted the diamonds to GIA are listed below as part of the GIA alert.
The GIA has “terminated submissions” from the following clients who submitted treated diamonds without disclosure: LYE Diamonds, E.G.S.D. Diamonds, Abramov Romok and Yair Matatov. Pending further investigation, RapNet and the Rapaport Group has suspended service to these companies and to the following individuals are believed to be associated with the companies: Nati Yizrov, Gavriel Yelizarov and Yair Matatov. RapNet will also delist all diamonds with recalled grading reports and will be contacting those listing such stones for sale.
Members of the trade that have access to such reports are asked to urgently email us at [email protected]. If the reports are in their possession they should cut them in half. The diamonds and the canceled reports may be sent to GIA for expedited free re-grading service. They may also be delivered to Rapaport offices in Israel, India and Belgium for this free service.
Buyers should be careful not to buy these diamonds based on the GIA grading reports and sellers should not sell the diamonds with these grading reports. The best course of action is to cut the canceled grading reports in half and return the diamond to the supplier against a full refund. If any RapNet members have difficulty returning diamonds, please email [email protected].
Additional information and updates about this Trade Alert will be posted on Diamonds.Net
Below is the full text of the GIA Laboratory Alert followed by the grading report numbers.
GIA Laboratory Alert
May 12, 2015 -- GIA reasonably suspects that approximately 500 colorless to near colorless diamonds submitted primarily to our laboratory in Israel potentially were subjected to an undisclosed temporary treatment.
GIA believes that the treatment is a process that temporarily masks the inherent color of the diamond and can lead to a higher grade. The color difference can be as much as three grades. GIA has not yet identified the treatment process, but this is being actively researched. At this time, the diamonds treated in this way have been submitted by just a few clients.
Report numbers with this suspected treatment are listed below and we ask anyone who has purchased or holds these diamonds to please re-submit them to any GIA location for review. GIA will expedite the service, and no fee will be assessed. We have terminated submissions from the clients who have submitted these diamonds to GIA and have notified the appropriate trade bodies.
