Botswanan diamond firm Debswana on Wednesday said, a 1,098-carat diamond had been unearthed and that it was the third largest of its kind in the world.
The firm also said it was the biggest stone of gem quality to be recovered in the history of the company, which is a joint venture between the Botswana government and global diamond giant De Beers.
The biggest diamond ever discovered in the world was the 3,106-carat Cullinan, found in South Africa in 1905.
The second largest was 1,109-carat Lesedi La Rona -- a diamond the size of a tennis ball, discovered at Karowe, northeastern Botswana, in 2015.
