Russian diamond monopoly ALROSA produces nearly all of the country's diamonds and also accounts for about a quarter of the world's rough diamonds. The organization, which is majority owned by the central government in Moscow and the Republic of Sakha, operates mines throughout Russia and Angola. About 50% of the company's rough diamonds are sold in foreign markets. ALROSA has a distribution agreement with De Beers' marketing arm, The Diamond Trading Company, but is steadily reducing the amount of diamonds it supplies to De Beers. The company also markets its own stones and supports a growing Russian diamond-cutting industry.
