Another highlight of the 250-lot auction at the Four Seasons Hotel des Bergues is what the auction house is calling the largest fancy vivid blue-green diamond in the world to come to auction. Known as “The Ocean Dream,” the 5.50-carat gem has an estimate of $7.5 to $9.5 million. “The combination of its size, natural origin, hue, and saturated color makes it an extremely unusual occurrence,” Christie’s said in a statement.

Other diamonds expected to generate strong international interest include a 76.51-carat light pink cut-corned diamond set as necklace centerpiece by diamond dealer Lev Leviev with an estimate of $7 to $10 million (pictured above); and a 75.97-carat pear-shaped D-color flawless diamond with an estimate of $13.5 million to $15 million (pictured below).
