The rare black diamond known as ‘Enigma’ went under the hammer in London for £3.16 million ($4.3 million). According to Agence France Press (AFP), it’s believed to be the world's largest cut diamond.
The 555.55 carat, 55-faced diamond was sold at an online auction that concluded on Wednesday. The stone is registered as the largest natural diamond in the world as of 2004 by diamond experts GIA and Gubelin, and the largest cut diamond in the world as of 2006 by the Guinness World Record book.
Unlike classic diamonds that are usually unearthed from deep undergrounds, black diamonds are often close to or on the Earth’s surface, which may possibly suggest extraterrestrial origins, stated Sotheby’s auction house.
“It is thought that this specific type of black diamond was created either from meteoric impacts producing natural chemical vapor deposition or an extraterrestrial origin - from supernovae explosions that formed diamond-bearing asteroids which ultimately collided with the Earth,” added Sotheby’s statement.
Today, these diamonds are found exclusively in Brazil or the Central African Republic. Their aggregated structure is the toughest in existence, making them nearly impossible to cut and polish. Enigma was bought in the late 1990s and would have weighed over 800 carats in the rough form. It took over three years to produce this uniquely shaped faceted specimen.
Its shape is inspired by the Middle Eastern palm symbol, a sign of protection and a tool of deflection against the evil eye. However, the highest price of an auctioned diamond remains with the Pink Star diamond, which was sold for $ 71.2 million at a 2017 auction also organized by Sotheby’s, in Hong Kong.
