De Beers "was established in 1888 and is the world's leading diamond company with unrivalled expertise in exploration, mining and marketing of rough diamonds.
It produces approximately 40% of the world's supply of rough diamonds from its mines in South Africa, and in partnership with the governments of Botswana, Namibia and Tanzania.
Approximately 45% of the world's rough diamond production (made up from diamonds from De Beers mines and those which De Beers purchases from Alrosa, the Russian state diamond mining company) are sorted and valued by the Diamond Trading Company, the sales and marketing arm of De Beers, headquartered in London."
