A 555-carat diamond of mysterious origin, estimated to be 1 billion years old, has sold at Sotheby’s for $ 4.5 million in cryptocurrency.

The origin of diamonds has confused geologists because it is still unclear whether they came from space or crystallized in the Earth’s mantle. The diamond has an opaque black appearance full of visible holes.

Carbon diamonds are only available in two regions of the planet, Brazil and the Central African Republic. However, what makes this carbonaceous diamond even more mysterious is the fact that it contains a group of minerals, such as the mineral titanium nitride, which are often found in meteorites.

Sotheby’s has not named the buyer, but businessman Richard Hart said on Twitter that he is the anonymous owner of the diamond.

Sotheby’s has not responded to Cointelegraph’s request for comment at the time of writing.

The auction house described supermassive diamonds as a very specific type of black diamond that was created either from meteor impacts or “of extraterrestrial origin – from supernova explosions that formed diamond-bearing asteroids that eventually collided with Earth.”

According to a report published in The Sun, Stephen Haggerty, a professor of soil and environment at Florida International University, said there is no reliable scientific theory to prove that this happened on Earth. He said:

“There was not a single scientifically sound alternative to the [extraterrestrial] origin of carbonado.”
Sotheby’s has become one of the first luxury auction houses to accept cryptocurrency as payment since October 2021. Similarly, the Australian auction house Lloyds Auctions announced that it would start accepting bitcoin (BTC) and other cryptocurrencies as payments in June 2021, and in September the auctioneer sold his long-lost Colin McRae racing car for $ 360,000 in bitcoin.

Christie’s, another large auction house, started it all off by selling a non-fungal $ 69 million Beeple token, managed by Ether (ETH). Since then, several auction houses have followed the group as cryptocurrencies have gained popularity as a simple payment method.
