Rare Black Diamond ‘The Enigma’ Sells for $5.7 Million


The backstory for “The Enigma” reads almost like a science fiction horror story. The rare gem is believed to have been either forged in the fiery crash of a meteor hitting the Earth, or it was carried on an asteroid that collided with our planet. Either way, if this were a sci-fi movie, “The Enigma” would be imbued with some special power or would carry some lethal virus that would bring the human race to its knees. Whether that’s the case or not, what is true is that this black diamond is extremely rare. Nikita Binani, a jewellery specialist for Sotheby’s in London, calls the diamond “a true natural phenomenon.” She goes on to say, “Its sale represents a once-in-a-lifetime opportunity to acquire one of the rarest, billion-year-old cosmic wonders known to humankind.”

The black diamond weighs in at an impressive 555.55 carats and carries trace amounts of nitrogen and hydrogen, which are found abundantly in interstellar space. You might also find osbornite in black diamonds, a mineral frequently found in meteorites. This isn’t the first black diamond to be found. Also known as Carbonado diamonds, black diamonds date back 2.6 to 3.8 billion years ago. “The Enigma” has been cut into a shape resembling the Middle Eastern palm symbol for Hamsa, which is a sing of protection and means, appropriately enough, “five” in Arabic.

“The Enigma” was originally acquired in the 1990s. At the time it was just a rough stone, but it has since been cut to have 55 facets, playing off of the theme of 5 so abundant with this stone. In addition to its rumoured birth among the stars, the stone holds the distinction of being the world’s largest cut diamond. Sotheby’s recently tweeted that the stone sold for £3.16 million (AUD$5.72 million) stating that “the buyer has opted to use cryptocurrency for the purchase.”
