The Karowe mine in Botswana has produced a 1,080-carat diamond—the fourth diamond over 1,000 carats recovered from the mine since 2015.
Mine owner Lucara describes the diamond, which measures 82.2 mm by 42.8 mm by 34.2 mm, as a “Type IIa top white gem of high quality.”
Lucara has been able to increase its recovery of big diamonds because of its use of advanced technology, detailed in a 2020 New Yorker article. Previously, diamonds over a certain size were crushed.
Per a current agreement, the diamond will likely be sold to HB Antwerp, which will give Lucara a portion of the final polished price. Lucara did not respond to a request for comment on the diamond’s possible value.
