About the Cullinan mine

Located at the foothills of the Magaliesberg mountain range, 37 kilometres north-east of Pretoria in South Africa, Cullinan 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. 

Cullinan is a famous source of large white diamonds and frequently yields diamonds larger than 10 carats.  Furthermore, it has produced over 800 stones weighing more than 100 carats, 140 stones weighing more than 200 carats, and around a quarter of all diamonds weighing more than 400 carats. 

Notable diamonds historically produced from Cullinan 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 famous Taylor-Burton diamond (69 carats polished).  More recently, the Cullinan Heritage (507 carats rough) was recovered by Petra and sold for US$35.3 million in February 2010, being at the time the highest price on record for a rough diamond. 

Cullinan is also renowned as the world’s most important source of blue diamonds, providing the collection of 11 rare blues displayed in 2000 at London’s Millennium Dome alongside the Millennium Star and which included the fancy vivid blue ‘Heart of Eternity’ (27 carats polished). Petra has recovered a number of important blue diamonds since acquiring a majority stake in the mine in 2008, including the Blue Moon of Josephine (12 carats polished, cut from a 29.6 carat rough diamond) which sold for US$48.5 million at auction in November 2015 (a world record price per carat for any polished diamond of just over US$4 million) and the Cullinan Dream (24 carats polished, cut from a 122.5 carat rough diamond), which sold for US$25.4 million at auction in June 2016.
