Bonhams Sells Every Jewel on Offer at New York Auction

Bonhams brought in $8.1 million at its Perfect Jewelry Box auction in New York as all 119 items found a buyer — in what the trade terms a “white-glove sale.”

The top piece was a 35-carat diamond ring by Leviev, which sold for $2.7 million at the March 8 event, beating its $2.5 million high estimate, the auction house said Wednesday.

“It was a privilege to present this collection, which had such a diverse mix of period jewels, rare gemstones and exceptional white diamonds,” said Caroline Morrissey, head of jewelry for Bonhams in New York. “Leading the sale were three type IIa, D-color diamonds, all over 10 carats, which is extremely rare. [The] results reflected the quality of the pieces offered.”

Here are the top five pieces:
