Vancouver, British Columbia – The Karowe diamond mine in Botswana has just delivered another diamond over 100 carats.
Owner and operator Lucara Diamond Corp. announced Monday that it has recovered a 692.3 carat stone from the mine.
The diamond, which measures 46.5 x 40.7 x 28.4 mm, is a Type IIa diamond. Lucara said it was found in the MDR (mega-diamond recovery) XRT unit during direct milling of ore from the mine’s south lobe.
The discovery of the 692-carat diamond comes less than two weeks after the company announced that the South Lobe had produced its fourth rough diamond of more than 1,000 carats since 2015.
The 1,080.1-carat diamond is also a Type IIa stone and was recovered from the Coarse XRT unit.
Lucara CEO William Lamb said the 692-carat diamond was the 20th stone of more than 100 carats recovered at Karowe so far this year.
He said the discovery “strongly supports” the company’s expectation of finding larger diamonds as it moves underground at the mine, as the majority of the material mined will be from the same phase of the kimberlite.
Lamb, who first served as Lucara’s CEO from May 2011 to February 2018, took up the role again earlier this month, replacing Eira Thomas.
Underground production at Karowe was originally expected to begin in the second half of 2026, but the company announced last month that it would take longer and cost more than originally planned.
