WHICH ARE VARIOUS GEMS DEPOSITS ON EARTH?

Diamond mines produce both gem-quality and industrial diamonds. Although most of the diamonds sold are industrial diamonds, the value of the gem diamond trade is much greater. Africa is the richest continent for diamond mining, accounting for around 49 per cent of world production. Artificial diamonds are made for use in industry. Most artificial diamonds are made in the United States.

A total of only 314 tonnes of diamond has ever been mined in the whole history of diamond mining. The world’s total of all gems, industrial, natural and synthetic is around 57 tonnes per year.

The world’s famous diamonds

The Star of Africa is the world’s largest cut diamond. It was cut from the biggest diamond ever found and is included in the British Crown Jewels. The Smithsonian pink diamond, although small, is extremely valuable because of its unusual colour.
