An exceptionally large and white 1,174-carat diamond stone has been unearthed in Botswana, trumping another huge precious stone found in the country last month. 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.
