Lucara Diamond Corp has sold the 549-carat Sethunya and the 1,080-carat Eva Star diamonds—both recovered from its Karowe mine in Botswana—for a total of $54 million.
The Sethunya, discovered in 2021, and the Eva Star, recovered in 2023, highlight the consistent production of large, high-quality diamonds from the South Lobe of the Karowe kimberlite.
Lucara affirms that these exceptional stones reinforce Karowe’s reputation as one of the world’s premier sources of high-value diamonds.
“The sale of these two extraordinary diamonds further validates our investment in the Karowe underground project,” said Lucara president and CEO William Lamb. “The unique mineralogy of Karowe’s kimberlite, especially in the South Lobe, continues to astonish us with its ability to yield exceptionally large and high-clarity Type IIa diamonds. The mine remains unmatched in delivering stones of remarkable size and quality.”
Karowe has a history of producing some of the world’s largest diamonds, including:
- The 1,758-carat Sewelô (2019)
- A 1,174-carat diamond (2021)
- The 1,109-carat Lesedi La Rona (2015)
The 1,080-carat Eva Star diamond is the fourth diamond exceeding 1,000 carats recovered from the mine. It follows the 2,492-carat Motswedi diamond, recovered in August 2023, and the 1,094-carat Seriti diamond, found in September 2023.
The Motswedi ranks as the second-largest diamond ever recovered, surpassed only by the 3,106-carat Cullinan diamond discovered in South Africa in 1905.
Looking ahead, Lucara’s Karowe underground expansion project is set to extend the mine’s life beyond 2040, granting access to deeper sections of the South Lobe rich in EMPKS ore. Underground production is expected to commence in the first half of 2028.
