The History Behind … Signet rings

time,” Churgin said. “They become tokens of inclusion or affiliation.”

When were they popular? By the Victorian era, signet rings had become a staple of the well-dressed gentlemen, and part of the revivals of Renaissance and ancient jewelry. Signet rings remained a staple through the Deco and wartime eras, and maintained a high level of quality and elegance.

By 1950, however, both style and craftsmanship plummet. “After that, most signet rings don’t have the same quality,” Doyle says. “Often they have cast crests, instead of hand-engraved, or machine engraving.”

Why did people wear signet rings? Essentially, for the same reason people wear them today. “Wearing signet rings makes you look important,” Churgin says. “For gentlemen, a good signet ring is comfortable but stately looking. With women, they ultimately speak of quality.”

What materials were used for these pieces? Originally, signet rings were made mainly of brass and copper, sometimes bronze or silver, but it’s the gold rings that survive, the ones owned by the wealthy classes.

Starting in ancient times, many signets were carved in hardstone, usually agate, onyx, carnelian, or sardonyx, sometimes lapis or garnet. Most experts include ancient intaglios as a type of signet.

How much are signet rings worth? At Doyle & Doyle, they range from $385 for an early 20th century 14-karat gold heart with a floral-engraved shank to $3,200 for a Victorian ring with a carnelian intaglio and an 18-karat buckle-shaped band.

An English signet ring, c. 1300, sold at Sotheby’s last year for $26,563, yet ancient Roman and Greek intaglio rings frequently go for less than $5,000 at Christie’s antiquities sales. Simple gold signet rings can be found for less than $200 at auctions, especially those based in London.

How can a retailer add signet rings to their antique jewelry offerings? “Start by adding the more accessible styles,” Doyle said. “As your following for this style of ring grows, you can add more unusual and collectible styles.”

Oval shapes and signets with a monogram or coat of arms are the most common, with round shapes coming in a close second. Carved hardstone is slightly less common but still accessible. Rectangle, square and shield shapes are rarer and very collectible.

Doyle said monograms are sometimes a hard sell because people want their own initials. This is one reason celebrities such as Rihanna turn to contemporary designers for vintage-style monogrammed signet rings, custom-engraved with their own initials.

“People tend to prefer the signet rings with crests and coats of arms,” she said. “The ones with monograms can be beautiful too but they’re so personal, they have less universal appeal.”
