Cullinan Mine Unearths Five Significant Blue Diamonds
The Cullinan mine is known as the world’s most important source of blue diamonds. It is therefore very exciting to hear that Petra Diamonds has announced the discovery of five blue diamonds of high quality at its Cullinan mine in South Africa.
These rough stones are significant in size, ranging from 9.61 carats up to 25.75 carats and are assessed as being individual stones opposed to being part of one larger stone.
The last most significant blue diamond weighing 20.08 carats, was unearthed from Cullinan a year ago. “It is therefore even more unusual to recover five high quality stones around the same time, all in the space of one week’s production”, commented the mine.
Given the current pandemic, Petra Diamonds is maintaining a flexible approach to the sale of these incredible stones. And with their last blue diamond (20.08ct) selling for $14.9m USD, speculation and anticipation will be high.
Cullinan, was the source of the world’s largest gem diamond ever recovered: the Cullinan diamond weighing an astonishing 3,106 carats in its rough form, was cut to create the Great Star of Africa and the Second Star of Africa, the two largest cut diamonds in the British Crown Jewels.
