World’s Biggest Diamond Is Going Up for Auction

The biggest uncut diamond on earth—and the second largest diamond ever found—is going up for auction in London Wednesday where it’s expected to sell for at least $70 million. The diamond, named Lesedi La Rona, meaning “Our Light” in the Tswana language of Botswana where it was found, is about the size of a tennis ball, too big to fit into traditional diamond scanners.
