Jewelry expert Joseph DuMouchelle offers a closer look at increasing demand for vintage signed jewelry at auction in the U.S. and globally.

In much the same way that fine art is signed by artists, quite often, so is exceptionally well-made jewelry, with signed pieces marked with a signature which denotes the designer, maker, or manufacturer. Particularly desirable among vintage pieces, demand for signed jewelry at auction has never been higher, according to an experienced jeweler and qualified gemologist Joseph DuMouchelle.

“Vintage signed jewelry has never been more sought-after or in higher demand at auction,” reveals DuMouchelle, an estate buyer, graduate gemologist, appraiser, auctioneer, and co-founder and president of Joseph DuMouchelle Fine & Estate Jewellers, LLC.

Easily identified by experts such as DuMouchelle, styles of signature or means of marking signed jewelry can vary, particularly with vintage pieces. “With the appropriate magnifying glass, known as a loupe, it’s possible to both identify a signature and to get a valuable, closer look at a particular piece of jewelry,” he explains.

While looking for a signature, there’s also the opportunity to look for other, interesting hallmarks, such as whether the piece is 18k or 24k gold, for example, according to DuMouchelle. “Learning to read different, particularly vintage signatures is an excellent way to give oneself the upper hand in dealing with vintage jewelry,” adds the expert and Joseph DuMouchelle Fine & Estate Jewellers co-founder.

From vintage Cartier art deco brooches to 1960s diamond-embellished Tiffany rings, pieces of vintage signed jewelry are today commanding higher prices than ever before at auctions throughout the United States and around the world. “Prewar, postwar, and mid-century pieces of signed jewelry from top brands and designers have become increasingly sought-after in the last decade,” DuMouchelle explains, “both here in the U.S. and internationally.”

Vintage signed pieces from jewelers and luxury retailers such as Tiffany & Co. and Italian designer brand Bulgari, as well as Van Cleef & Arpels, French luxury goods conglomerate Cartier, and American jeweler Harry Winston have all commanded record or near-record auction prices in recent years.

“Demand only looks set to increase from here on out,” suggests DuMouchelle, wrapping up, “so there’s never been a better time to buy or, arguably, sell vintage signed jewelry, particularly at auction.”
