Finding the Right signet-rings for You

Traditionally considered a ring for men, a vintage signet ring is a popular gift today for anyone who desires an expressive, timeless piece of jewelry that can feature all manner of engraved motifs, gemstones, specific symbols or monograms.

Whether it's an antique gold signet ring, diamond signet ring or some other classic iteration, signet rings get their name from signus, which means “sign” in Latin.

These rings, which may historically be referred to as “seal rings,” date back thousands of years and were used as a form of signature. Whatever may have been engraved on the ring — a married couple’s initials, a family crest — identified ownership for the purposes of authenticating documents and more when impressed on soft wax. During the Middle Ages, signet rings were symbols of power and prestige and common accessories for nobility. Later, during the 19th century, precious and semiprecious stones such as rubies and diamonds were added to gold signet rings as they took on a more ornate appearance than they had previously. 

In recent years, fashion has been primarily about individuality, and nothing is more personal than a jewel bearing a name or monogram. That is the reason jewelers have revived traditional signet rings, custom-engraving their designs with customers’ preferred words or symbols. Those who prefer the thrill of the hunt have a range of vintage letter charms and pendants to sift through.

And it isn't all about men's signet rings anymore, either — the accessory is for everyone. Princess Diana wore a signet ring that was a gift from Charles before their wedding, and we all know that the royals are top-tier fashion influencers, especially when it comes to rings.

Find vintage diamond signet rings, onyx signet rings and other types of rings on 1stDibs.

Questions About 18ct Gold Signet
  • 1stDibs ExpertSeptember 28, 2021
    The gold signet ring is traditionally a symbol of heritage. It is often handed down through the generations of a family. It is also known as the “gentleman's ring” or “seal rings.” The name comes from the Latin 'Signum' which means “sign.” On 1stDibs, find a variety of antique and vintage gold signet rings.
  • 1stDibs ExpertJune 30, 2023
    Whether 18-karat gold is valuable depends on a variety of factors. The price of gold per gram fluctuates with the market for gold. If the gold in question refers to a piece of jewelry, factors under consideration would include the style of the piece, if the accessory features any gemstones and what the gems are, where it was made, its condtion and more. A certified appraiser can evaluate 18-karat gold jewelry to determine its value. On 1stDibs, shop a collection of 18-karat gold jewelry from some of the world's top sellers.
  • 1stDibs ExpertNovember 14, 2023
    Yes, 18-karat gold can be good for earrings. Because it is an alloy, 18-karat gold is more durable and scratch-resistant than pure 24-karat gold. You can find 18-karat gold in rich warm yellow, cooler white with warm undertones and light pink rose. On 1stDibs, explore a large collection of gold earrings.
  • 1stDibs ExpertNovember 8, 2023
    Whether 14-karat or 18-karat white gold is better for a wedding band depends largely on your preferences. If you like the look of white gold with a warmer tone, you may wish to opt for 18-karat gold because it often appears yellower due to its higher gold content. On the other hand, 14-karat white gold wedding bands tend to be durable, making them a good option for people most concerned with keeping their rings scratch-free. Find an assortment of white gold wedding bands on 1stDibs.
  • 1stDibs ExpertNovember 1, 2023
    The difference between 14K and 18K white gold stud earrings comes down to the content of the precious metal alloy. Stud earrings made of 14-karat white gold are 58.3% gold and 41.7% base metal, while 18-karat gold is 75% pure gold and 25% other metals. As a result, 14-karat white gold tends to be stronger and more resistant to scratching, and 18-karat gold will have a more noticeable warm-glowing yellow tinge. On 1stDibs, shop a range of white gold stud earrings.
