How do I know that my diamond certificate or diamond grading report is from an independent laboratory ?
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.
Which one of the 4 C’s of diamond grading is the most important ?
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.

De Beers sightholders refuse boxes Update
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.
