Lucara Diamond Corp. announced Thursday that the Karowe diamond mine in Botswana has yielded another big stone, this one weighing 472 carats.
The diamond, described as a “top light brown” stone, is the third largest diamond ever recovered from Karowe, which also yielded the 1,109-carat diamond dubbed the “Lesedi La Rona,” which was purchased by Graff Diamonds in September for $53 million.
The second-largest diamond ever found at Karowe was the 812.77-carat “Constellation” diamond, which was discovered just a few days after the Lesedi La Rona in the fall of 2015. The Constellation sold in May 2016 for $63 million.
Lucara CEO Eira Thomas said that this year the company is focused on mining at the high-value south lobe, which is known as a consistent source of diamonds weighing more than 10.8 carats.
