A black diamond weighing 555.55 carats has been put up for auction.

 It’s called the Enigma. Bidding for the auction will take place from February 3 to 9, and cryptocurrencies can also be used.

Sotheby’s, the company that organized the auction, said it was the largest black diamond ever put up for auction.

It was listed in the Guinness World Records in 2006 as the largest polished diamond. The diamond was unveiled in Dubai last week and will be on display in Beverly Hills this week.

It will then be taken to London for auction. According to market reports, the diamond is expected to fetch between $ 4 million and $ 7 million.
