The world’s largest and flawless blue diamond will go under Christie’s hammer in Geneva next month, with the rare gem expected to fetch up to $25 million, the auction house has revealed.
“The Blue”, a sparkling 13.22 carats pear-shaped rock, also known as “blue perfection”, is supposed to be “the largest fancy vivid blue diamond in the world,” according to Christie’s.
While the auction house would not reveal the diamond’s owner, it said it had been in the holder’s possession for a long time.
If recent auctions in Geneva are any indication, “The Blue” could fetch more than $25 million. When the world’s largest orange diamond, a 14.82-carat gem called “The Orange”, which went under the hammer last November, was sold for $35.5 million more than double its $17-20 million price tag.
