910-Carat Rough Diamond Sells for $40M
It’s the fifth-largest diamond ever found and has been named “The Lesotho Legend.”

London--The fifth-largest diamond on record has a new owner and a new name, mining company Gem Diamonds Ltd. announced Tuesday morning.
The 910-carat diamond—said to be a Type IIa, D color stone—recovered in January from the Letšeng mine in Lesotho was sold at tender in Antwerp Monday for $40 million and dubbed “The Lesotho Legend.”
The diamond’s sale price works out to $43,956 per carat, putting it well below the world record per-carat price for a rough diamond, $77,649. That was set by the 812.77-carat Constellation, mined by Lucara Diamond Corp. in Botswana.
A Gem Diamonds spokesperson told National Jeweler Tuesday morning that Samir Gems, an Antwerp-based supplier founded in 1982 and run by the Bhansali family, purchased the stone with partners.
In a company news release, CEO Clifford Elphick said the company is “delighted” with the sale of the 910-carat diamond, which reaffirms the “unique quality of the Letšeng diamond production.”
