A diamond believed to be the third largest ever found has been put on display in Botswana. The stone, weighing 1,098 carats, was shown to President Mokgweetsi Masisi, two weeks after the diamond firm, Debswana, unearthed it. The huge gem is only slightly less heavy than the world's second-largest diamond which was also found in Botswana in 2015. Botswana is Africa's largest producer of diamonds. The biggest diamond ever discovered was the 3,106 carat Cullinan diamond found in South Africa in 1905. Botswana's Minerals Minister, Lefoko Moagi, said the latest find could not have come at a better time for Botswana after the pandemic caused diamond sales to slump last year. The newly discovered stone, which was found at the Jwaneng mine, is yet to be named.
