South Africa’s Petra Diamonds has recovered a 342.92-carat Type IIa white rough at its iconic Cullinan mine.

Located at the foothills of the Magaliesberg mountain range, 37 kilometres north-east of Pretoria in South Africa, the Cullinan Mine is one of the world's most celebrated diamond mines.

It 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. This iconic stone was cut into the two most important diamonds which form part of the Crown Jewels in the Tower of London – the First Star of Africa, which is mounted at the top of the Sovereign’s Sceptre and which at 530 carats is the largest flawless cut diamond in the world, and the Second Star of Africa, a 317 carat polished diamond which forms the centrepiece of the Imperial State Crown.

The Cullinan 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.
