7. CULLINAN DIAMOND MINE
The Cullinan, also known as the Premier Mine, was established in 1902. On 22 November 2007, De Beers, the world’s largest diamond producer, sold its historic Cullinan mine to Petra Diamonds Cullinan Consortium (PDCC), a consortium led by Petra Diamonds. The mine is home to some of the world’s largest, gem-quality diamonds – including the largest rough, gem-quality diamond ever found and the two largest diamonds in the British Crown Jewels.
