The largest fancy intense blue diamond ever offered at auction is to go under the hammer in Christie’s New York Magnificent Jewels on 9 June 2016.
The auctioneer expects the cut-cornered rectangular mixed-cut, 24.18-carat, VS2 gem named Cullinan Dream to fetch US$23 million to US$29 million, or up to US$1.2 million per carat.
The Cullinan Dream is the largest of the four blue diamonds cut from the extraordinary 122.52-carat rough that Petra Diamonds discovered in June 2014 at the legendary Cullinan mine in South Africa. The other three polished stones weighted 7 carats, 10.30 carats and 11.30 carats. Petra Diamonds will receive 15 percent of the proceeds from the sale of the Cullinan Dream.
