The largest ever diamond to come to auction was previewed by Christie's in Hong Kong ahead of its sale in November. Saskia O'Donoghue reports
It's the largest diamond to ever come to auction. This 163.4-carat flawless white diamond was previewed by Christie's in Hong Kong on Thursday. It's expected to bring in a excess of 30 million U.S. dollars. Christie's European Chairman said he had never come across anything like it. (SOUNDBITE) (English) CHRISTIE'S EUROPE CHAIRMAN, FRANCOIS CURIEL SAYING: "This is the first time a 163-carat diamond flawless come on the market. The largest stone that ever come up on the market before of this quality was 110-carats. So this is a stone that is 50 percent bigger than the previous one. It's an absolute rarity." The 404.20-carat rough diamond was found in an Angolan mine in 2016. It's the largest ever to be found in the country, according to the jewellers who acquired it. (SOUNDBITE) (English) DE GRISOGONO FOUNDER, FAWAZ GRUOSI, SAYING: "That was really something more than exceptional. Because being 404 carats sometimes you see black right and left, but it was totally clean. And it was like a miracle. So it took time to re-cut it. It took a bit over a year. And it came out, something, which was just to look at it the first time. I had some emotion. Which normally I don't have because I am used to all of this." The diamond, which can be detached from its current necklace setting, goes on the block in Geneva on November 14.
