HEX.com diamond

The HEX.com diamond[1] is the largest cut diamond in the world as of 2006, holding the Guinness World Record.[2] Containing 55 facets and weighing in at 555.55 carats (111.11 grams), it was commissioned and inspired by Ran Gorenstein (Belgium) and completed in 2004 after several years of cutting and faceting. The repetitive use of the number five in the design of the gem is intentional deriving from the hamsa, a palm shaped amulet popular among Muslims and Jews in the Middle East and North Africa.[3]

The diamond is a carbonado or black diamond. It is semi-transparent with a dark brown color. Typically, black diamonds have been reserved for industrial uses with larger specimens considered as collectors’ stones, and in fact most of gem-quality used in contemporary jewelry design have been treated to produce the black color. A natural faceted black diamond of this size is an extremely rare occurrence.

The origin of the diamond is uncertain, but it is believed to either be the result of a meteoric impact or part of an asteroid that crashed on Earth.[3]

In February 2022, the diamond was bought by cryptocurrency entrepreneur Richard Heart for £3.16 million and renamed from its original name of the Enigma.[1]
