Bonhams June Fine Jewelry Sale Shows Diamonds are in Demand

Jewelry collectors, admirers and members of the trade vied for 121 lots of fine jewelry offered and sold by Bonhams in New York City on June 19, 2007. The auction brought nearly $1.5-million and included strong results for fresh-to-market material. The sale was simulcast to the West Coast where clients placed bids from both Los Angeles and San Francisco, where Bonhams & Butterfields’ salesrooms hosted the participants.

Large diamonds were of particular demand, and were the highlights of the day. Featured from the Singer-Smith Estate from Connecticut was the sale catalog’s cover lot — an unusual old cushion-cut yellow diamond weighing 19.62ct which sold for $228,000. An 8.78ct. rectangular diamond sold for $78,000.

Art Deco jewelry is showing increasingly strong prices as demonstrated by a ‘tutti frutti’ watch brooch selling for $15,500. An unusually large Art Deco brooch signed Marcus and Co. sold for $40,000.

Signed mid-century jewelry sold extremely well. A collection from a Chicago estate included a David Webb necklace which brought $15,600, while a pair of Webb earrings from the same estate sold for $8,400. An unusual cabochon sapphire ring sold for $13,800, along with a diamond and platinum covered wristwatch signed Ruser and Rolex which sold for $22,800.

Featured this fall will be exciting jewelry highlights such as a large private Florida collection with more than 40 pieces of period jewelry. Featured will be an Art Deco Cartier bracelet, a Tiffany & Co. ruby and diamond bracelet, an early diamond and ruby necklace by Tiffany & Co., and an 11.00ct. round brilliant cut diamond.
