$15M Blue Diamond to Hit Christie’s Auction Block

A blue diamond pendant will be among the headliners in next month’s Christie’s sale in New York, where it is expected to bring in up to $15 million.

The pear modified brilliant-cut, 31.62-carat, fancy-blue stone, surrounded by white and pink diamonds, is potentially internally flawless, Christie’s said Tuesday. A pear brilliant-cut, 86.64-carat, D-color, VVS1-clarity diamond pendant will join it at the December 6 Magnificent Jewels sale. That piece, which hangs from a chain of 78 diamonds between 0.50 and 2.50 carats, is estimated at $5 million to $7 million.

Other notable items include a torque bangle bracelet bearing a heart brilliant-cut, 50.05-carat, D-color, internally flawless diamond, with a presale price of $3.7 million to $4.5 million.  A modified pear double rose-cut, 5-carat, fancy-vivid-blue diamond ring has an upper estimate of $4 million and no reserve. An oval brilliant-cut, 51.60-carat, G-color, VS2-clarity diamond ring carries a high price of $2.8 million.

Christie’s will also offer an unmounted modified pear brilliant-cut, 104.04-carat, fancy-intense-yellow diamond. That jewel has an upper estimate of $2.5 million, as does a round-cornered square brilliant-cut, 107.46-carat, fancy-yellow diamond brooch by Graff. Meanwhile, an emerald-cut, 13.75-carat, fancy-vivid-yellow, internally flawless diamond ring by De Beers and an oval brilliant-cut, 2.21-carat, fancy-intense-blue diamond ring are set to fetch up to $1.8 million each.

Those items join the star of the show: An emerald-cut, 13.15-carat, fancy-vivid-pink diamond ring that Christie’s expects will fetch up to $35 million at the auction.
