There was another major diamond discovery at South Africa’s Cullinan mine this month as Petra Diamonds recovered a 232-carat diamond.
The white diamond is a D-color, type IIa stone with “exceptional” size and clarity. It is also the second large diamond recovered by Petra Diamonds from the mine this year. In June, the company recovered a 122.5 carat blue diamond, the largest blue diamond found by Petra since they acquired the Cullinan mine in 2008.
The Cullinan mine has been a great source for diamonds since it opened in 1902. The mine, located in the small African town of the same name, is just east of Pretoria, Guateng, South Africa. According to a recent tweet by Petra Diamonds, there have been over 800 diamonds found in the mine that weigh over 100 carats and 130 diamonds at over 200 carats.
The location first became famous in 1905 with the discovery of the 3,106 carat Cullinan Diamond. Over a century later, it is still the largest rough diamond ever recovered. The stone was eventually broken down into 9 large diamonds and an additional 96 smaller diamonds.
Other famous diamonds found at the Cullinan Mine include:
- The Golden Jubilee Diamond, the largest cut and faceted diamond in the world. Recovered in 1985, it weighed in at 755.5-carats. After two years of cutting, the brown diamond is a Fire Rose Cushion-Cut stone weighing in at 545.67-carats.
