Lucara Rides Mega-Diamond Hot Streak With Another +1,000-Carat Discovery

You can say that Lucara is riding a mega-diamond hot streak. Less than a month after the mining company announced the recovery of an incredible 2,492-carat rough diamond from its Karowe Mine in Botswana, it is back in the news with the discovery of a high-quality 1,094-carat rough.

August’s head turner ranked as the second-largest diamond ever found, and this most recent recovery ranks as #7. Of the 10 largest diamonds ever mined, seven of them were sourced in Botswana, and six of the seven came from the Karowe Mine. (Botswana’s Jwaneng Mine secured the sixth-ranked 1,098-carat gem in 2021).

Holding onto the #1 spot is the 3,106-carat Cullinan, which was found at South Africa’s Premier Mine 2 in 1905.

Lucara noted that the 1,094-carat rough was discovered in Karowe’s south lobe, which has historically produced large, high-value diamonds. The stone bears striking similarities to the 692-carat diamond the company unearthed in August 2023. That stone, which ranks #23, was polished by HB Antwerp and yielded diamonds that sold for more than $13 million.

The mining company confirmed that this newly recovered stone also will be polished by HB Antwerp as part of the ongoing partnership between the two companies.

As with the 2,492-carat rough diamond, this newest find benefitted from Lucara’s state-of-the-art Mega Diamond Recovery (“MDR”) X-ray Transmission (“XRT”) technology, installed in 2017 to identify and preserve large, high-value diamonds.

“The recovery of this exceptional 1,094-carat diamond is a testament to Karowe’s remarkable potential and further validates our investment in the underground expansion project,” said company president and CEO William Lamb. “These continued discoveries of large, high-value diamonds demonstrate the consistent quality of our resource and its ability to deliver substantial returns.”

Lucara’s $683 million underground expansion at Karowe aims to extend the life of the mine beyond 2040.
