On the heels of the discovery of a 1,080 ct. Type IIa diamond earlier this month, Lucara has found another huge gemstone at its Karowe mine in Botswana.

The company describes its newest find—a 692.3 carater that measures 46.5 x 40.7 x 28.4 mm—as a Type IIa high white gem. It is the fourth diamond weighing over 300 carats that Lucara has recovered at the mine this year.

“This stone is the 20th diamond larger than 100 carats recovered during 2023 at Karowe,” said CEO William Lamb in a statement.

Its discovery “strongly supports our expectations for the underground [production of Karowe],” he added.

Lamb was just appointed CEO of Lucara, taking over from Eira Thomas. He had served as Lucara’s CEO from May 2011 to February 2018.

The underground development of Karowe has gone way overbudget—so much so that Lucara recently said the cost overruns might threaten the company’s ability to function as a going concern.
