Tennis ball sized diamond

A 3-billion-year-old tennis ball sized diamond— the largest discovered in over a century — could sell for more than $70 million, auctioneer Sotheby’s said Wednesday.

The tennis ball sized diamond  was unearthed in November in Botswana at a mine owned by Canada’s Lucara Diamond Corporation. It measured 1,109 carats, the second-largest gem-quality rough diamond ever discovered. Its name means “our light” in the Tswana language of southern Africa.

The auctioneer said the rough gemstone “of exceptional transparency” could yield the largest top-quality diamond ever cut and polished.
David Bennett, chairman of Sotheby’s jewelry division, called the discovery “the find of a lifetime” and the auction unprecedented.
“Not only is the rough superlative in size and quality, but no rough even remotely of this scale has ever been offered before at public auction,” he said.


The largest diamond ever found was the 3,106-carat Cullinan diamond, unearthed in South Africa in 1905. It was cut into nine pieces that form part of the U.K. Crown Jewels.

The tennis ball sized diamond  could smash the record price for a diamond of $48.5 million, paid at a Geneva sale last year for the 12.03-carat polished “Blue Moon” diamond. Hong Kong billionaire Joseph Lau picked it up as a gift for his 7-year-old daughter.
