Botswana says one of the largest diamonds ever found has been unearthed at one of its mines and will be put on show. Canadian mining company Lucara Diamond Corp. said in a statement that it recovered the “exceptional” rough diamond from its Karowe Mine in western Botswana. Lucara said it was a “high-quality” stone and was found intact. It was located using X-ray technology. The weight would make it the largest diamond found in more than 100 years and the second-largest ever dug out of a mine after the Cullinan Diamond discovered in South Africa in 1905.
