If you like Blue Diamonds, then you were in for a treat at Christie’s December 6th Magnificent Jewels sale held at Rockefeller Center in New York.

All in all, the auction went quite well, achieving slightly over $62.5 million and featured some unexpected entries to be featured in the top 10. Let’s briefly look at the top lots…

The Graff Blue Diamond Ring

Le piece de resistance of the auction was a crossover platinum ring designed by Graff.

The piece features two brilliant-pear cut, Fancy Vivid Blue stones. The first weighing in at 3.36 carats, and having a VVS2 clarity grading, and the second standing at a slightly smaller 2.71 carats with a VS1 grading.

All together the ring sold for over $12.5 million, far exceeding its $8.5 million pre-auction high estimate.

 Other Notable Diamonds:

While the Graff Blue left everyone in awe, 2 colorless diamonds also managed to impress visitors, shattering their pre-auction high estimates. Let's briefly look at both: 

  • The first; a beautiful 38.91 carat, square-step shaped stone with cut corners. This gem was set in a platinum ring and was accompanied with three baguette cut diamonds on each side. All together, the piece yielded slightly over $3.6 million, just exceeding its pre-auction high estimate.
  • The second; a 23.26 carat, brilliant, round cut stone. This diamond was mounted in platinum and exceeded everyone’s expectations when it sold for over $2.3 million. A whopping $800 thousand above its $1.5 million pre-auction estimate.

A Gem To Remember

While not a fancy colored or colorless diamond, the Belle Époque Kashmir sapphire rightfully took its place among the top 10 lots of the auction. The 11.81 carat stone was embedded in a beautiful diamond ring and sold for a very respectable $1.7 million, exceeding its $1 million pre-auction high estimate.

The Top Lots for Signed Jewelry

Signed jewels were also extremely popular. Among the most notable sales were:

Harry Winston

A beautiful diamond cluster circlet necklace designed by Harry Winston made a strong appearance among the featured signed pieces. The lot was sold for a respectable $1.8 million, remaining within the pre-auction estimates.

JAR

JAR also made a notable appearance with the truly magnificent multi-gem “Flower” ear pendants. The pieces featured a myriad of purple, violet, blue, clear, yellow, and green stones of various cuts and carat weights. All together, the lot yielded a little over $1.2 million, also falling within its pre-auction estimates.

 Rivière

Rivière presented a beautiful necklace; with a platinum base, the piece was set with a graduated series of 46 brilliant, round cut diamonds. The piece easily sold for $1.1 million, exceeding its pre-auction high estimate of $1 million.

 Van Cleef & Arpels

An item that surprised most with its appearance in the top lots was Van Cleef & Arpels’ natural pearl and diamond pendant earrings. Measuring 11.90-11.95 x 22.50 mm and 11.35-11.40 x 21.50 mm respectively, the pearls were mounted in a beautiful platinum embedded with small round cut diamonds. The earrings managed to yield a respectable $972,500, falling within their pre-auction estimates.

While the above pieces were absolutely stunning and highly anticipated to perform well, there were 2 lots that managed to surprise everyone with their appearance in the top 10 sales. These were:

  • A George Fouquet, multi-gem bracelet designed by Adolphe Mouron Dit Cassandre which managed to sell for $925 thousand, well above its $600 thousand pre-auction high estimate.
  • A pair of platinum and diamond ear pendants by Cartier also left us dumbfounded as they sold for $324,500, shattering the pre-auction high estimate of $60,000.

 The Biggest Surprise of All

Sitting upright, the piece is set with with hundreds of diamonds, rubies and emeralds of multiple sizes and cuts. The lot managed to sell for over $1.5 million. Unfortunately, a pre-auction estimate was never provided, further supporting everyone’s surprise with this beautiful item making it to the top sales.
