Miners have just discovered one of the world's biggest diamonds



High-up in the mountains of Lesotho in southern Africa, Gem Diamonds Ltd has discovered an astonishing 910 carat diamond- which is the fifth-biggest ever to be discovered.

Specifically, the stone is a D colour Type IIa diamond and is about the size of two balls. This specification means that it has very few or no nitrogen atoms, thus making it one of the most expensive types of diamonds.

The discovered occurred at the company’s Letseng mine which is famous for the size and quality of the diamonds it produces and has the highest average selling price in the world. To put the scale of this discovery in perspective, Gem Diamonds sold a 357-carat stone for $19.3 million in 2015.

Commenting on the discovery, Clifford Elphick, Chief Executive Officer of Gem Diamonds, said:

“Since Gem Diamonds acquired Letseng in 2006, the mine has produced some of the world’s most remarkable diamonds, including the 603 carat Lesotho Promise, however, this exceptional top-quality diamond is the largest to be mined to date and highlights the unsurpassed quality of the Letseng mine. This is a landmark recovery for all of Gem Diamond’s stakeholders, including our employees, shareholders and the Government of Lesotho, our partner in the Letseng mine.”

The discovery will come as a significant confidence boost to Gem Diamonds which had recently been forced to close a new mine in Botswana due to poor rates of recovery of large stones.

The biggest diamond ever discovered remains the 3,106-carat Cullinan, found near Pretoria, in South Africa in 1905. It was cut to form the Great Star of Africa and the Lesser Star of Africa, which are set in the Crown Jewels of Britain. Lucara’s 1,109-carat Lesedi La Rona is the second-biggest, with the 995-carat Excelsior being third and the 969-carat Star of Sierra Leone coming in as the fourth-largest.
