Finding the Right rings for You

Antique and vintage rings have long held a special place in the hearts of fine jewelry lovers all over the world.

No matter their origin or specific characteristics, rings are timeless, versatile accessories. They’ve carried deep meaning since at least the Middle Ages, when diamond rings symbolized strength and other kinds of rings were worn to signify romantic feelings or to denote an affiliation with a religious order. Rings have also forever been emblematic of eternity.

Over time, rings have frequently taken the form of serpents, which have long been associated with eternal life, health and renewal. Italian luxury jewelry house Bulgari has become famous for its widely loved Serpenti motif, for example, and its Serpenti ring, like the other accessories in the collection, began as an homage to jewelry of the Roman and Hellenistic eras. The serpent is now a popular motif in fine jewelry. Jewelry devotees have long pined for rings adorned with reptiles, thanks to antique Victorian rings — well, specifically, Queen Victoria’s illustrious engagement ring, which took the form of a gold snake set with rubies, diamonds and an emerald (her birthstone). Designs for Victorian-era engagement rings often featured repoussé work and chasing, in which patterns are hammered into the metal.

Engagement rings, which are reliably intimidating to shop for, are still widely recognized as symbols of love and commitment. On 1stDibs, a range of buying guides can be found for those in the market for antique engagement ringsvintage engagement rings or Art Deco engagement rings

The most collectible antique engagement rings and vintage engagement rings are those from the Victorian, Edwardian and Art Deco eras. Named for the monarchies of the four King Georges, who in succession ruled England starting in 1714 (plus King William’s reign), antique Georgian rings, be they engagement rings or otherwise, are also coveted by collectors. Pearls, along with colored gemstones like garnets, rubies and sapphires, were widely used in Georgian jewelry. The late-1700s paste jewelry was a predecessor to what we now call fashion or costume jewelry

The Art Nouveau movement (1880–1910) brought with it rings inspired by the natural world. Antique Art Nouveau rings might feature depictions of winged insects and fauna as well as women, who were simultaneously eroticized and romanticized, frequently with long flowing hair. Art Deco jewelry, on the other hand, which originated during the 1920s and ’30s, is by and large “white jewelry.” White metals, primarily platinum, were favored over yellow gold in the design of antique Art Deco rings and other accessories as well as geometric motifs, with women drawn to the era’s dazzling cocktail rings in particular.

Whether you’re hunting down a chunky classic for a Prohibition-themed cocktail party or seeking a clean contemporary design to complement your casual ensemble, find an exquisite collection of antique, new and vintage rings on 1stDibs.

Questions About Square Opal Engagement Rings
  • 1stDibs ExpertNovember 2, 2023
    Yes, an opal engagement ring can last if you care for it properly. Generally, opals are more delicate than other gemstones commonly used in engagement rings, like diamonds, sapphires and emeralds. As a result, they can be easily damaged, making it important that you take your ring off before performing household chores, exercising, playing sports or doing other activities where you'll use your hands a lot. Find a collection of opal engagement rings on 1stDibs.
  • 1stDibs ExpertNovember 6, 2023
    No, opals aren't bad for engagement rings. One drawback of the gemstone is that it isn't as hard as many other popular gems, like diamonds, emeralds and sapphires, so it may be more susceptible to scratches. However, you can still choose an opal engagement ring if you wish. Taking it off before you engage in activities that could damage the ring can help extend its life. Shop an assortment of opal engagement rings on 1stDibs.
  • 1stDibs ExpertFebruary 22, 2021
    No, opal is not good for engagement rings. Although opal is a beautiful stone, it is not the best choice for an engagement ring. Since they are relatively fragile compared to diamonds and sapphires, opals are not durable for daily wear.
  • 1stDibs ExpertFebruary 22, 2021
    While opals are more fragile than diamonds, adding a higher risk for a daily-wear ring, they can still be good engagement rings. Opals are thought of as precious and powerful and are said to symbolize fidelity so can be great and unique rings.
  • 1stDibs ExpertFebruary 22, 2021
    Yes, opal engagement rings can be a good idea. This stone represents faithfulness, confidence, and creativity -- making the stone a fitting choice for an engagement ring. Opals, however, are not ideal for everyday wear.
