Vancouver, British Columbia—The Karowe Diamond Mine in Botswana just delivered another 100-carat-plus diamond.

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 from direct milling of ore sourced 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 weighing more than 1,000 carats since 2015.

The 1,080.1-carat diamond also is a Type IIa stone and was recovered in the Coarse XRT unit.
