De Beers expands Diamdel auctions to DTC sightholders

In a statement released on Monday, De Beers said DTC sightholders - who comprise its exclusive list of rough diamond buyers - would become part of the Diamdel auctions from October.  DTC sightholders collectively handle approximately 75 percent of the world's diamonds and are mainly based in the diamond traditional cutting centres.

Diamond Trading Company Botswana has 16 such sightholders who participate in 10 sights or sales weeks spread throughout the year.  DTC's other centres in London, South Africa, Namibia and its offices for Canadian sightholders and industrial buyers also hold 10 sights per year.
