The diamond firm Debswana has announced the discovery in Botswana of a 1,098-carat stone that it described as the third largest of its kind in the world.

It is the third largest in the world, behind the 3,106-carat Cullinan found in South Africa in 1905 and the 1,109-carat Lesedi La Rona discovered in Botswana in 2015.

“This is the largest diamond to be recovered by Debswana in its history of over 50 years in operation,” Armstrong said.

“From our preliminary analysis it could be the world’s third largest gem-quality stone.
