Next month, Christie’s will offer the largest and, arguably, the highest-quality fancy vivid blue diamond ever seen at auction. Named for its previous owner, the late Sir Philip Oppenheimer (a member of the family that runs the De Beers diamond company), the 14.62-carat, rectangular-cut Oppenheimer Blue Diamond is one of the standout lots from Christie’s Magnificent Jewels event in Geneva. The diamond is estimated to sell for $38 million to $45 million.
Colorful diamonds like the Oppenheimer continue to command high prices at auction. For additional expert analysis on this phenomenon and tips on more essential collection items, see Three Smart Jewelry Investments. (christies.com)
