Its fame skyrocketed in 1905 with the discovery of the Cullinan Diamond, the largest gem-quality rough diamond ever found, weighing an astonishing 3,106.75 carats. This single event cemented the mine’s place in history and initiated a saga of royal jewels and unparalleled diamond cutting.

The sheer size and frequency of large diamond discoveries at Cullinan set it apart from other diamond mines globally. Throughout the 20th century, its operations evolved, incorporating advanced mining techniques to safely and efficiently extract the valuable gems from deep within the earth.
