Cullinan mine is owned by Petra Diamonds and is situated in the Gauteng province of South Africa and the site of the open-pit mine is located about 40km east of Pretoria.

In 1905, the largest rough gem diamond was found in Cullinan. The discovery of the diamond – which has 3 106 carats – put Cullinan mine on the global map as a renowned source of large, high quality gem diamonds. This includes type II stones and is a source of very rare blue diamonds.

The mine has an expected life span of about 50 years. Cullinan contains a world-class diamond resource of 194 metric carats (Mcts). The mine has undertaken an expansion programme that is expected to increase annual production from 0.7Mcts in 2016, to 2.2Mcts in 2019.
