Ensuring public trust in gems and jewellery is the goal of Gemological Institute of America’s (GIA’s) recent change to its lab-grown diamond reporting.
The nonprofit American Gem Society (AGS) Laboratories has announced an expansion to its diamond grading capabilities. It will now grade brown diamonds as well as their white counterparts.
The first time Jason Quick laid eyes on the Esperanza diamond, he was awestruck by the way light moved through the rough crystal. It was love at first sight, as he puts it, a once-in-a-lifetime encounter with the 8.52-carat diamond unearthed at Arkansas’ Crater of Diamonds State Park.
Gemological Institute of America (GIA) say it has developed a fully automated system to rapidly and accurately analyze and sort round D-to-Z melee-size diamonds.
Only 175 of the 1042 diamonds with altered reports have been returned to Gemological Institute of America (GIA) following news its database had been hacked and grading reports altered.
It would seem consumers are now aware of the jewellery industry’s dirty little secret: diamond grading is subjective. Though many graded stones are generally accepted as accurate to the issued report, there are just as many reports containing grading errors or bias.
