The Botswana government says the huge 2,492-carat diamond is the second-biggest ever discovered in a mine. It’s the biggest diamond found since 1905.
The as-yet-unnamed diamond was presented to the world at the office of Botswana President Mokgweetsi Masisi. It weighs approximately half a kilogram and Masisi was one of the first to get to hold it, the AP reported.
Officials said it was too early to value the stone or decide how it would be sold. Another smaller diamond from the same mine in Botswana was sold for $63 million in 2016, a record for a rough gem.
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.
