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

31.62-carat, blue diamond pendant

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.

Blue Diamond Sells for $14M at Sotheby’s

Sothebys Blue Ring

Sotheby’s brought in a total of $40.2 million at its Hong Kong auction Wednesday as a 5 carat blue diamond fetched $13.8 million.

The price of the step cut, fancy vivid blue, named the Ai diamond, after the Chinese word for love, fell within its estimate of $12.5 million to $15.3 million. The final selling price translated to $2.8 million per carat.

Another blue diamond a pear shaped, fancy intense blue weighing 3.47 carats sold for $3.1 million at the Magnificent Jewels and Jadeite auction against a pre-sale estimate of $2.7 million to $3.6 million. A step cut, 18.45 carat, D color, VVS2 clarity diamond ring fetched $2.3 million, smashing its estimate of $1.3 million to $1.7 million.

However, only one piece out of a collection of jewels by designer Wallace Chan found a buyer: a pair of jade and diamond earrings, estimated at $70,160 to $108,430, which went for $87,700.

Several jewels by Harry Winston, Van Cleef & Arpels and Cartier also sold at the auction.

Sotheby’s sold 65% of all lots on offer, it said.
