World’s biggest uncut diamond sells for $53 million

A model holds the 1,109-carat uncut diamond. London: British jeweller Graff on Tuesday said it has purchased the world’s largest uncut diamond — roughly the size of a tennis ball — for $53 million.

Canadian miner Lucara Diamond sold to Graff the 1,109-carat gem, the Lesedi La Rona, which was found in Botswana’s Karowe mine in late 2015.

“We are thrilled and honoured to become the new custodians of this incredible diamond,” said company chairman, Laurence Graff, in a statement. “The stone will tell us its story, it will dictate how it wants to be cut, and we will take the utmost care to respect its exceptional properties.”

The rough diamond had previously failed to meet its reserve price of more than $70 million at a Sotheby’s auction in 2016.

Graff is already the owner of a 373-carat diamond which formed part of the original stone. Lesedi La Rona means “our light” in Botswana’s Tswana language.
