1,305-Carat Diamond Recovered from Mine in Botswana
Lucara Diamond Corp. announced it has recently recovered a diamond weighing 1,305.4 carats from its Karowe diamond mine in Botswana.
The stone is categorized as white and is unbroken, the miner said, and measures 79.9 mm x 34.1 mm x 51.9 mm.
The huge rough diamond was detected by the Mega Diamond Recovery (MDR) X-ray Transmission (XRT) machines, which Lucara said have been instrumental in preserving and recovering large gem-quality diamonds.
The stone was found while processing a blend of open-pit material and previously mined, unprocessed stockpiled ore. As a result, Lucara said it cannot conclusively determine whether the diamond originated from the site’s open-pit mine or from run-of-mine stockpiled material.
The 1,305-carat stone is the 10th diamond weighing more than 1,000 carats that the miner has recovered since mining began at Karowe in 2012.
It is the only diamond mine in the world to have yielded 10 diamonds exceeding 1,000 carats, according to Lucara.
Among them have been the 1,109-carat Lesedi La Rona in 2015 and the 1,080-carat Eva Star in 2023, as well as the 2,488-carat Motswedi—the largest diamond discovered in more than a century—and the 1,094-carat Seriti, which were recovered within a month of each other in 2024.
The recent discovery reinforces Karowe as “the world’s most prolific source of exceptionally large, high-value diamonds,” Lucara said.
