A Billion-Year Old Black Diamond Was Just Bought with Crypto for $4.3M

A very expensive natural color black diamond, called “The Enigma” has recently been sold for $4.3 million at auction and was paid for with cryptocurrency.

The diamond, which weighs 555.55 carats according to Sotheby’s, was named the world’s largest cut diamond as of 2006.

The gem was displayed in London between Feb. 2-9 and sold in an auction for £3.16 million ($4.3 million).

The auction house confirmed in a tweet on Wednesday that the black diamond had been bought using cryptocurrency but did not name the buyer.

Entrepreneur Richard Heart tweeted that he had won the diamond and would be renaming it the “HEX.com diamond,” after his blockchain deposit certificate business.

Sotheby’s called the diamond “one of the rarest, billion-year-old wonders known to humankind.”

“The Enigma” is a carbonado diamond, which is found in deposits close to, or on, the Earth’s surface, indicating that it could have come from space.

“It is thought that this specific type of black diamond was created either from meteoric impacts producing natural chemical vapor deposition or an extraterrestrial origin — from supernovae explosions that formed diamond-bearing asteroids which ultimately collided with the Earth,” Sotheby’s said.
