Extremely Rare 555.55 Carat Black Diamond To Be Auctioned Off

One of the largest and rarest diamonds on the planet is set to be auctioned off next month. The 555.55 carat black diamond – known as ‘The Enigma’ – set the Guinness World Record as the largest cut diamond in 2006.  It’s believed to have arrived on Earth from outer space via a meteorite. The diamond is heading to London in February, where it will be sold by the world-famous Sotheby’s auction house.   It’s expected to fetch somewhere in the ballpark of $6.8 million – and in case you’re wondering, Sotheby’s says it will accept crypto as payment. How much do you think it will sell for?
