A diamond that could be formed in space


Also known as carbonado diamond, it is possible that this black diamond came from outer space. Carbonados of this structure have so far only been found in Brazil and the Central African Republic, and scientists have long theorized about their origin.


According to the magazine Futura Science, this kind of diamond would not have been born on Earth, at moderate pressures and temperatures, but in a much more exotic environment. Indeed, the combination of the composition of carbonados and the knowledge of the thermochemical processes capable of producing them strongly suggest that carbonaceous matter in a molecular and dusty interstellar cloud was compressed and heated by the shock wave of a supernova explosion. The carbonados would then have been incorporated in the matter of the oldest meteorites formed in the protoplanetary disk of the Solar System.

They’re shrouded in mystery as to where they came from or how they were formed, because we don’t find many of them on Earth,” geologist Aaron Celestian, curator of mineral sciences at the Natural History Museum in Los Angeles, told Reuters on Wednesday. “We think they may have formed very deep inside the Earth, much deeper than what we already know about diamonds. There are hypotheses that suggest they formed at impact sites where a large asteroid hit the Earth” .


The Enigma has never been exhibited before and is expected to be sold for between $4 and $7 million. Its owner has owned it for two decades, but little is known about its history before that.


The diamond, which was displayed in Dubai last week, was shown in Beverly Hills this week before returning to London for the auction at Sotheby’s on February 3.
