Tucked away just 40 kilometres east of Pretoria lies the legendary Cullinan Diamond Mine. This mine is a glittering symbol of South Africa’s rich mining history. Offering exclusive surface tours, the mine welcomes curious adventurers eager to discover the secrets behind some of the world’s most famous and valuable diamonds.
A Legacy Carved in Stone
The Cullinan Diamond Mine was formerly known as the Premier Mine and was established in 1902. The mine quickly made its mark on history with the discovery of the Cullinan Diamond in 1905. Weighing a staggering 3,106 carats (or 621 grams), it remains the largest rough gem-quality diamond ever found. The diamond was named after Thomas Cullinan, the mine’s chairman at the time, and was then cut to produce two of the most iconic diamonds in the British Crown Jewels: the Great Star of Africa (530 carats) and the Lesser Star of Africa (317 carats).
In 2003, the mine was renamed Cullinan to honor this historical find and reinforce its link to the regal past. Today, under the stewardship of Petra Diamonds, the mine continues to operate as one of the most prolific sources of gem-quality stones, particularly the extremely rare and valuable blue diamonds.
