Recently, according to media reports, on January 17, local time, the "world's largest cut diamond" was exhibited in Dubai. The diamond will be auctioned online by Sotheby's on February 3, with an estimated price of at least £5 million (about 43.34 million yuan). Named "Enigma", the black diamond has 55 facets and is 555.55 carats, and was certified the world's largest cut diamond by the Guinness Book of World Records in 2006.
It is reported that diamond prices continue to rise in 2021, on the one hand, because production is limited, transportation and other costs have risen, on the other hand, because with the economic recovery, the demand side ushered in a strong rebound, especially in China and the United States.
The extremely rare black diamond is said to have been "formed by chemical vapor deposition" when a meteorite or asteroid hit Earth 2.6 billion years ago, or it could have come from outer space itself. Its design is derived from the Middle Eastern folk guardian khamsa [xamsa], which has the iconic number 5.
