Sotheby's will auction a 101.38-carat diamond this Friday in Hong Kong. In exchange, one of the world's largest auction houses accepts payments in Bitcoin or Ethereum.

Experts at the auction house believe that buyers can aim for as much as $15 million. If so, this will be the most expensive object ever to be bought at auction via cryptocurrencies.

As Josh Pullan, managing director of the luxury department of Sotheby's, contacted by Bloomberg, clarifies, "there are more and more young people connected to digital media and cryptocurrencies who want to buy stones of ten precious. To date we have auctioned nine diamonds over 100 carats, but only two other than this one were pear-shaped.

In May, Sotheby's announced that it would accept the digital currencies Bitcoin and Ethereum in the sale of a piece by British artist Banksy, the first time an auction house had admitted this type of payment.

Specifically, Banksy's work, entitled "Love Is in the Air," was auctioned during the New York Contemporary Art Evening Sale on May 12, considered one of the most important of the year, and was valued between three million and five million dollars.
