The latest find, which fills the palm of a man’s hand, was discovered on June 12 by Canadian Diamond firm, Lucara and presented to the country’s cabinet in the capital Gaborone on Wednesday.

“This is history in the making, for us and Botswana as well,” said the company’s managing director Naseem Lahri, adding that the diamond sits in third position among the world’s largest gemstones.

In terms of size of large stones, “it actually sits as number three in the hierarchy,” Lahri told AFP.

The latest find solidifies Botswana as a leader on the world stage of the largest stones, accounting for six in the top ten list.

The biggest diamond ever discovered in the world was the 3,106-carat Cullinan, found in South Africa in 1905. Parts of that diamond adorn the British crown jewels.
