Producer
Historically, the rough diamond price has been controlled by De Beers Group, which has an estimated 40% to 50%[1] of the market. Botswana is currently the largest producer of diamonds with mines operated by Debswana, a joint venture between De Beers and the Botswana government. However, since the 1980s, other producers have developed new mines in Russia, Canada and Australia for example, challenging De Beers' dominance (historically De Beers market share was considerably higher, e.g. 80%). De Beers through its trading company known as the Diamond Trading Company (DTC) raised wholesale diamond prices three times in 2004 by a total of 14%.
Buyer
The United States is the biggest consumer of diamonds in the world. The U.S. accounts for 35% of diamond sales, Hong Kong 26%, Belgium 15% (Antwerp is the world's diamond-trading centre), Japan 6%, and Israel 4% [2]. Israel and Belgium in particular are important Hubs for trading diamonds thus consumption numbers are misleading. The price of diamonds fluctuates with global demand and the world economy.
Polished diamond prices vary widely depending on a diamond's carat, color, clarity and cut (The 4 C's). In contrast to precious metals, there is no universal world price per gram for diamonds. However the industry does use tools such as the Rapaport Diamond Report, Ajediam Antwerp Diamonds Monthly and The Gem Guide which are published weekly or quarterly, as a price references.
