GABORONE - The world's third-largest diamond has now been put on display in Gaborone, Botswana.
An estimate of the stone's cost is yet to be released, but in 2017 the world's second-largest diamond -- also found in Botswana -- was sold for $53-million.
Diamond firm Debswana says it unearthed a stone weighing 1,098-carat at its Jwaneng mine.
The biggest diamond ever discovered was the 3,106-carat.
The Cullinan Diamond was found in South Africa in 1905.
Botswana is the continent's largest producer of diamonds.
Debswana is a joint venture between the Botswana government and diamond giant, De Beers.
