Cullinan Diamond Mine

The Cullinan Diamond Mine is renowned as a source of large, high-quality gem diamonds, including Type II stones, as well as being the world’s most important source of very rare blue diamonds. Cullinan earned its place in history with the discovery of the Cullinan diamond in 1905, the largest rough gem diamond ever found at 3,106 carats, which was cut to form the two most important diamonds in the British Crown Jewels.

Many of the world’s most famous diamonds herald from Cullinan, and it continues to produce world-class diamonds under Petra’s stewardship. The Cullinan orebody contains a major diamond resource of 195 Mcts, suggesting a potentially long life for the operation of +50 years. 6 million in 2014.
