In Pics | Enigma, world's largest known, 555.55-carat cut diamond
The world's largest known cut diamond went on public display for the first time ahead of its sale, when it is expected to reach five million dollars. One of the most difficult substances to cut, the Enigma, the 555.55-carat diamond has never been shown by its unnamed owner of the past 20 years, but experts turned it into a 55-face jewel.
