One of the biggest diamonds in history has been discovered in the mountainous kingdom of Lesotho in southern Africa.
Gem Diamonds Ltd. found the 910-carat stone, about the size of two golf balls, at its Letseng mine in the country. It’s a D color Type IIa diamond, which means it has very few or no nitrogen atoms and is one of the most expensive stones. The diamond is the fifth-biggest ever found.
The Letseng mine is famous for the size and quality of the diamonds it produces and has the highest average selling price in the world. Gem sold a 357-carat stone for $19.3 million in 2015 and in 2006 found the 603-carat Lesotho Promise.
“This exceptional top-quality diamond is the largest to be mined to date and highlights the unsurpassed quality of the Letseng mine,” Chief Executive Officer Clifford Elphick said in a statement.
