World’s largest rough diamond to auction for $70m in London

The largest rough diamond the ‘Lesedi la Rona’ will be put up for auction in London next month and is anticipated to sell for US$70 million, international auction house Sotheby’s announced yesterday.

The 1,190-carat diamond, its name meaning ‘Our Light’ in Botswana’s Tswana language was recently on display at Sotheby’s in New York.

David Bennett, Sotheby’s worldwide jewellery division chairman said the sized has amazed experts. “It really just soared off the scale of rare into something, just, one off, it’s just unique,” he added.

Discovered in Botswana in 2015 by Canadian mining company Lucara Diamond, the piece is believed to be two and a half billion to more than three billion years old.

Diamond mining in Africa has been tainted over the past ten years by rebels forcing people to mine but the Kimberley Process Certification System, a United Nations programme, has made diamond trafficking increasingly difficult.

Sotheby’s reported the Lesedi la Rona could have potential to produce the biggest diamond ever seen, once cut and polished.

“It’s worthwhile for people to come and look at it because you probably won’t be seeing it again in two or three years’ time,” said Bennett.

The auction will take place on the 29 of June in London.
