There are a number of ways to verify that your diamond matches the diamond certificate it is purchased with. If you purchased a diamond that is laser inscribed, ask your jeweller to show you the laser inscription under magnification. This way, you will always be able to identify the diamond as your own.
DCLA also performs a verification service, for both DCLA certified diamonds and for diamonds certified by other internationally recognised laboratories. Bring or send your diamond, together with the diamond grading certificate, to the DCLA laboratory and the diamond will be conclusively matched against the certificate. DCLA can then cold laser inscribe the diamond with either the diamond grading certificate number, or with a personalised message.
Ask the jeweller if the diamond certificate comes from an independent diamond laboratory or if it produced by a diamond merchant or retailer, then do your research. Make sure the certificate is issued by the DCLA or another highly respected diamond grading laboratory; DCLA is the only diamond grading laboratory worldwide to offer a full-replacement Diamond Grading Guarantee.
Anglo American’s De Beers, the world’s largest rough diamond producer by value, has decided to begin selling its own polished diamonds in auctions for the first time in its history.
The pilot auction, scheduled for June, will include a wide range of polished stones manufactured directly from the company’s own rough diamonds.
"The pilot auction, scheduled for June 29, will include a wide range of polished stones manufactured directly from De Beer’s own rough diamonds." All the polished rocks will carry grading reports from both the International Institute of Diamond Grading & Research (IIDGR) — De Beers’ in-house grading unit — and the Gemological Institute of America (GIA).
“We are interested in testing the level of demand from polished buyers for diamonds that have a clear and attractive source of origin, and that offer the assurance of product integrity that dual certification provides,” Neil Ventura, the miner’s executive vice president of auction sales, said in the statement.
If successful, the process would provide De Beers with more insight into the polished market, while also helping consumers fill gaps in supply or inventory if they were unable to find goods at the company’s rough auctions, he added.
All registered De Beers auction buyers will be eligible to bid in the first sale, which takes place on June 29.
