Thrice-listed company Petra Diamonds sold on June 9, 2016, its 24.18 ct diamond, the Cullinan Diamond, at an auction for $25.37 million. Last month while announcing the auction sales, the firm said it would receive 15% of the sales proceeds.

Cullinan Dream is one of four blue diamonds cut and polished from a larger 122.52 ct stone found by the firm at its Cullinan diamond, in South Africa. The three other stones weigh 11.3 ct, 10.3 ct, and 7 ct respectively.

The Cullinan mine is renowned for the famous diamond discoveries made there. Indeed, in 1905, the world’s biggest raw diamond weighing 3,106 ct was discovered there. Since Petra Diamonds acquired the mine in 2008, the firm has found other big blue diamonds including the Blue Moon of Josephine, a 12.03 ct stone sold for $48.5 million mine.
