Diamond Larger Than A Tennis Ball Found In Botswana Mine

The largest uncut diamond in recent history has been unearthed in a mine in Botswana. It’s larger than a tennis ball, and second only to South Africa’s famous Cullinan Diamond.

The announcement was made Thursday by Lucara Diamond Corp which found the treasure at its Karowe mine in Botswana, beating the Canadian company’s own record discovery from November 2015.

The 1,758-carat diamond – which it said is larger than a tennis ball – weighs close to 352 grams (12.42 ounces), Lucara said in a statement.

The stone is second in size only to the 3,106-carat Cullinan Diamond, recovered in South Africa in 1905.

Lucara’s shares rose as much as 11.4% to the highest in more than two months, before closing up 6.3% at C$1.68.

The stone is the latest in a series of high-value recoveries for the Vancouver-based company at Karowe. Since introducing its XRT diamond recovery technology, Lucara has recovered 12 diamonds over 300 carats, the company said, including a 472-carat and a 327-carat diamond in April 2018.

The 1,109-carat “Lesedi La Rona,” which Lucara recovered in November 2015, failed to meet its undisclosed reserve price at a June 2016 auction, putting pressure on the company’s shares.

The company struggled to sell for nearly two years, until British diamond dealer Graff Diamonds finally bought it for $53 million in September 2017.

Forbes reported late last year that Graff had created 67 finished gems from the stone.
