(IDEX Online) - GIA says it has expanded its new verification service - aimed at combating "cloned diamond" fraud - to all its labs.The Report Confirmation Service was launched last month in New York to identify lab growns being submitted for regrading as natural diamonds.GIA says the service is now available at all locations. It will accept walk-in and courier submissions, will turn around loose diamonds in as little as 15 minutes, and will, initially, make no charge.The service is available for GIA-graded diamonds with and without inscriptions. An original GIA cert is helpful but not essential.An increasing number of lab growns are being fraudulently submitted for re-grading. They are cut to match the specifications of natural diamonds that have already been graded and inscribed with either with a GIA number (genuine or fake)."Combatting this fraud is vital to protecting the public and ensuring their confidence in gems and jewelry - this is GIA's mission," said GIA president and CEO Susan Jacques.Pic of diamond inscription courtesy GIA.
