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.
The DCLA is the only internationally affiliated and locally accredited diamond grading laboratory in Australia. Although there are other highly respected laboratories internationally, the DCLA is the only recognised diamond grading laboratory located in Australia, making it easier for Australians to deal with any problems or queries as they arise. In addition, DCLA is the only diamond certification laboratory to stand behind our work and offer a full-replacement Diamond Grading Guarantee.
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.
All of the 4 C’s are equally important; however, many people consider diamond cut to be the most important diamond characteristic, because even if a diamond has perfect colour and clarity, a diamond with poor cut quality will have dulled brilliance and life.
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.
Another D colour Type II diamond weighing 80 carats has been recovered.
Shares in Gem Diamonds spiked on Thursday after the miner announced it had recovered one of the highest quality stones to come out of its Letseng mine in Lesotho.
The discovery of this 80 carat diamond comes less than a month after the miner announced the recovery of a 114 carat rough diamond. And two years after Gem Diamonds found a 357 carat rough diamond, which sold for $19.3 million.
Gem Diamonds has recovered four of the 20 largest white gem quality diamonds ever recovered, which makes of the Lesotho mine the world’s highest dollar per carat kimberlite diamond operation.
Petra Diamonds announced that it had recovered a 138.57-carat, Type IIa, D-colour diamond at its historic Cullinan mine near Pretoria in South Africa. The company said the diamond would be offered for sale in Johannesburg later this month.
De Beers’s the world’s largest rough producer felt the pain, when only $300 million of the $450 million estimated sight was taken up by their sightholders. This leaves 30 percent of the rough on offer on the table.
Anglo has previously counted on diamond revenues to offset a collapse in the price of other metals and minerals it mines. Anglo may cut the company’s dividend for the first time since 2009 according to analysts.
This is an indication of turmoil in the $80 billion diamond industry as traders, cutters and polishers suffer from a poor liquidity and weaker demand for jewellery.
Producers in India, where 90 percent of rough diamonds are cut and polished, may halt imports over the supply glut.
Update: Report sightholders may have refused 35%-50% at July sight which may be as low as $200M.
