555,55-carat black diamond Enigma is displayed in Sotheby's auction house in Dubai, United Arab Emirates.
Enigma, which is also in the Guinness World's Records book, is going to be under the hammer and it is expected to find a buyer from $5,000,000.
It is believed that the diamond formed 2,600 billion years ago as a result of a meteor or an asteroid hitting the earth.
Following Dubai, Enigma is going to be exhibited in Los Angeles and Londra too.
After that, it is going to be sold in an online 7-day auction on February 3.
It is also stated that cryptocurrencies are to be accepted in the diamond's sale.
