The Cullinan Diamond Mine has been the source of some of the world’s most famous diamonds – The Centenary Diamond, The Taylor Burton Diamond and The Cullinan Diamond – the largest diamond ever found.
This magnificent gem was sized at 3106 carats and was cut into nine major stones – including the Greater and Lesser Stars of Africa, centrepieces of the British Royal Sceptre and State Crown respectively – as well as 96 smaller diamonds. More recently Cullinan Diamond Mine has continued to produce extraordinary gems to take their place in this astounding lineage.
The dazzling Star of Josephine took its place as the most expensive polished gem diamond sold on auction when the vivid fancy blue 7.03 carat gem was sold for US$ 9.48 million in May 2009. Blue diamonds are among the rarest diamonds in the world and the Cullinan Diamond mine is the most prominent source of these sought after gems.
The Cullinan Heritage diamond was ranked as one of the top 20 largest diamonds in the world and sold for an incredible US$ 35.3 million in February 2010, the highest price achieved for a rough diamond. "The Cullinan mine has again given the world a spectacularly beautiful and important diamond," said Johan Dippenaar, Petra Diamond's chief executive officer.
