About the 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.
Many of the most famous diamonds in the world herald from the Cullinan Mine and it continues to produce world-class diamonds under Petra's stewardship. Notable diamonds historically produced from the Cullinan Mine include:
· the Premier Rose (353 carats rough);
· the Niarchos (426 carats rough);
· the De Beers Centenary (599 carats rough);
· the Golden Jubilee (755 carats rough); and
· the Taylor-Burton diamond (69 carats polished).
More recently, remarkable diamonds recovered by Petra at the Cullinan Mine include:
· the Cullinan Heritage (507 carats rough white diamond), sold for US$35.3 million in 2010;
· the Blue Moon of Josephine (29 carats rough blue diamond), sold for US$25.6 million in 2014;
· the Cullinan Dream (122 carats rough blue diamond), sold for US$25.3 million in 2016; and
· the Legacy of the Cullinan Diamond Mine (424 carats rough white diamond), sold for just under US$15 million in May 2019.

About blue diamonds
Blue diamonds are one of nature's most special treasures. They are so rare that there are no official statistics on their recovery, however the Cullinan Mine in South Africa is known as the world's most important source.
The natural blue colour is derived from small amounts of the chemical element boron trapped in the crystal carbon structure during their formation. Virtually every blue diamond described by the GIA Gem Trade Laboratory as "blue" is classified as a Type IIb diamond.
High quality blue diamonds command the very highest values, with the 12 carat polished Blue Moon of Josephine selling for US$48.5 million in 2015, representing a remarkable +US$4 million per carat (US$20 million per gram).
