Sapphire Diamond Signet For Sale on 1stDibs

On 1stDibs, you can find the most appropriate sapphire diamond signet for your needs in our varied inventory. Each design created in this style — which was crafted with great care and often made from gold, 18k gold and yellow gold — can elevate any look. In our selection of items, you can find a vintage example as well as a contemporary version. If you’re looking for a sapphire diamond signet from a specific time period, our collection is diverse and broad-ranging, and you’ll find at least one that dates back to the 18th Century while another version may have been produced as recently as the 21st Century. A sapphire diamond signet from J DAUPHIN, Shima Azman and Thomas Kurilla Jewelry — each of whom created a beautiful version of this treasured accessory — is worth considering. A sapphire diamond signet of any era or style can lend versatility to your look, but a version featuring diamond, from our inventory of 162, is particularly popular. A round cut version of this piece has appeal, but there are also brilliant cut and oval cut versions for sale. When shopping for a sapphire diamond signet, you’ll find that there are less available pieces for unisex or men today than there are for women.

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 Sapphire Diamond Signet
  • 1stDibs ExpertFebruary 22, 2021
    Unless the sapphire is much bigger, a diamond is typically more expensive because it's rarer and harder.
  • 1stDibs ExpertApril 5, 2022
    No, sapphire diamonds are not real diamonds. They are actually white or colorless sapphire gemstones. Diamonds are pure carbon, while sapphires are corundum minerals that contain aluminum oxide and trace elements. On 1stDibs, find a large selection of expertly vetted diamond gemstone jewelry.
  • 1stDibs ExpertOctober 19, 2021
    A white sapphire is any gem-quality corundum that is either white or colorless. With a few exceptions, a white sapphire looks remarkably similar to a diamond in terms of cut and color. Diamonds will always appear brighter and have more colorful flashes than sapphires. Both diamonds and sapphires are hard and will resist everyday scratches. On 1stDibs, find antique and vintage diamond jewelry and white sapphire jewelry today.
  • 1stDibs ExpertDecember 4, 2023
    Yes, white sapphires look like diamonds. However, their appearances aren't completely identical. Although both are white or clear gemstones, the sparkle of a white sapphire will usually appear silvery or gray in color, while diamonds have a rainbow-colored sparkle due to how light interacts with them. Shop a wide range of white sapphire and diamond jewelry on 1stDibs.
