The biggest diamond in over a century is found in Botswana — a whopping 2,492 carats

The largest diamond found in more than a century has been unearthed at a mine in Botswana. The country’s president showed off the fist-sized stone at a viewing ceremony Thursday. The Botswana government says the 2,492-carat stone is the second-biggest ever discovered in a mine. It’s the biggest diamond found since 1905 and weighs about half a kilogram. Officials said it was too early to value it or decided how it would be sold. Botswana, a country of 2.6 million people in southern Africa, is the second-biggest producer of natural diamonds behind Russia and has unearthed all of the world’s biggest stones in recent years. The Karowe Mine has produced four other diamonds over 1,000 carats in the last decade.
