The world’s largest cut black diamond, known as “The Enigma”, was sold at the famous auctioneer's Sotheby’s in London for $4.3 million. The auction house confirmed that the diamond was bought using cryptocurrency, though they didn’t confirm the name of the buyer.
However, the founder of HEX.com, Richard Heart, tweeted to say that he had won the lot and would be renaming the diamond the “HEX.com diamond.”
