This gem is from out of this world. Literally.
Meet ‘The Enigma,’ a 555.55-carat black diamond that is going to be sold at an auction by Sotheby’s in February. The rare gem is believed to have come from outer space. According to the auction house’s jewelry specialist, Sophie Stevens, the diamond was formed in outer space. "With the carbonado diamonds, we believe that they were formed through extraterrestrial origins, with meteorites colliding with the Earth and either forming chemical vapor disposition or indeed coming from the meteorites themselves," she said.
The gem is expected to be sold for at least 5 million British pounds ($6.8 million).
