GABORONE (Botswana): A massive 2,492-carat diamond — the second largest in the world — has been discovered in Botswana, the Canadian mining company that found the stone announced Thursday.

The diamond was discovered in the Karowe Diamond Mine in northeastern Botswana using x-ray detection technology, Lucara Diamond Corp. said in a statement.

Lucara did not give a value for the find or mention its quality. But in terms of carats, the stone is second only to the 3,016-carat Cullinan Diamond discovered in South Africa in 1905.

“We are ecstatic about the recovery of this extraordinary 2,492-carat diamond,” Lucara president William Lamb said in the statement.—AFP
