Petra Diamonds has announced that it has recovered a 39.34 carat Type IIb blue diamond at the Cullinan mine in South Africa.
The diamond is said to be of exceptional quality in terms of its colour and clarity. It is anticipated that the diamond will be sold through special tender.
The Cullinan mine is an important source of rare blue diamonds, although it is most famous for the historical discovery of the 3,106 carat Cullinan Diamond in 1905, the largest rough gem diamond ever found. It is also the source of many large high-quality gem diamonds including famous gems such as the De Beers Centenary, the Blue Moon of Josephine, the Taylor-Burton diamond and the Cullinan Dream.
