Miners in Botswana recently unearthed what officials say is the second largest diamond in mining history. The country’s president Mokgweetsi Masisi presented the large stone to the public at a ceremony last week. The 2,492-carat gem is the biggest diamond to be discovered since 1905. The diamond weighs around a half-kilogram. Masisi was one of the first people to get to hold it. He expressed surprise at the diamond’s heaviness and told the gathering, “I am lucky to have seen it in my time." Lucara Diamond, a Canadian mining company, found the stone. Company officials said it was too early to value the gem or decide how it would be sold. A smaller uncut diamond from the same mine in Botswana sold for a record $63 million in 2016.
