A rare black diamond, believed to be billions of years old, has recently sold for $4.3 million. However, one of the most interesting details of the sale is that it was sold in crypto.

Details Of The Black Diamond Sale

The Enigma, as the diamond is called, weighs 555.55 carats. It was put on sale by Sotheby’s and is believed to be the world’s largest cut diamond since 2006. The Enigma belongs to a class of diamonds called carbonado diamonds, which are found close to or on the surface of the earth. Consequently, there have been suggestions the Enigma might be from space. According to Sotheby’s the black diamond could have even come from a supernova explosion, which formed diamond-bearing asteroids that eventually landed on earth.

Most other diamonds are formed deep within the Earth. As a result, they lack most of the minerals found in those diamonds formed deep inside the earth. Carbonados instead contain traces of hydrogen and nitrogen, which are found in large amounts in interstellar space. They also contain osbornite, which is often found in meteorites. These diamonds are usually 2.6 to 3.8 billion years old. Meanwhile, the earth is 4.5 billion years old.

Bought Using Crypto

Sotheby’s later revealed that the diamond had been successfully sold. They revealed via a tweet that the buyer had bought The Enigma for $4.3 million and opted to pay using crypto. However, the auction house did not reveal the identity of the buyer. Later on, the entrepreneur Richard Heart, revealed via a tweet that he had bought the diamond. He added that he plans to rename it the HEX.com diamond, which is the name of his blockchain deposit certificate business.

Where Are These Diamonds Found?

On earth, Carbonados are only found in the Central African Republic and Brazil, which were connected in the past. They used to be part of the Rodinia supercontinent. According to Sotheby’s the meteorites carrying the diamonds landed on earth at around that time when Brazil and CAR were still part of the supercontinent.

The reason they have a dark appearance is the randomly-oriented diamond grains. These grains absorb more light, which gives the diamond a dark color. Sotheby’s noted that their structure made it nearly impossible to cut and polish them. The auction house said that it took over three years to shape The Enigma to its current form. Originally, the diamond weighed over 800 carats.
