The top lot of the auction was a 22.46-carat rectangular-cut E color diamond ring  by David Webb, which sold for $1.9 million to an anonymous bidder.

A 14.82-carat pear-shaped E color diamond realized $1.6 million, or $107,500 per carat.

 

A 15.65-carat, F color round diamond  realized $1.5 million, or $98,300 per carat.

 

“Diamonds have been the flavor of the season, with top prices achieved in Geneva, Hong Kong and New York through spring 2012 as seasoned collectors and new economies went head-to-head for the best,” Rahul Kadakia, head of jewelry for Christie’s Americas, said.

 

Overall, the auction was sold 89 percent by lot and 92 percent by value.
