RAPAPORT... Auctioneers Christie’s and Sotheby’s (as usual) generated much excitement in the diamond trade in 2017, putting some of the more interesting and colorful diamonds under the hammer. As the Rapaport News team looks back on an eventful year, we’ve compiled a summary of the major auction events from the two larger auction houses — and their headline stones — that caught the eye: 


Christie’s New York auction in April totaled $35.2 million, with a rectangular, 22.03-carat, D, IF Van Cleef & Arpels diamond ring selling for $2.6 million. 

The June Magnificent Jewels auction in New York fetched $26.1 million, with Harry Winston buying the 18.04-carat Rockefeller Emerald ring for $5.5 million, or $305,516 per carat. 

The auction house generated $95 million at its May Geneva auction, with a heart-shaped, 92.15-carat, D-flawless diamond selling for $15 million, or $162,611 per carat.

Christie’s headlined its November Geneva auction by selling the emerald-cut, 163-carat, D-flawless Art of de Grisogono, Creation 1 necklace for $33.7 million, or $206,266 per carat. The stone can also be worn as a bracelet (pictured). Total sales at the auction amounted to $106 million. 

Meanwhile, during the same month in Hong Kong, Christie’s garnered $94 million as an oval, 14.93-carat, fancy vivid pink, VVS1 diamond fetched $32 million, or $2.1 million per carat.
