Petra recovers 138.57 ct white diamond at Cullinan

11 august 2016
Petra Diamonds has recovered a 138.57 carat Type IIa, D colour diamond at its Cullinan mine in South Africa.
It said in a statement that the diamond would be offered for sale as part of the company’s next sales process end of this month in Johannesburg.
Cullinan was a famous source of large white diamonds and frequently yields diamonds larger than 10 carats.

The mine had 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.
The largest rough gem diamond ever found in the world – a 3,106 carat stone – was discovered at Cullinan in 1905.
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 was mounted at the top of the Sovereign's Sceptre and which at 530 carats was 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 was 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'.
