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 Cushion Diamond Flawless
  • 1stDibs ExpertApril 5, 2022
    A flawless diamond is a diamond that has no inclusions or blemishes visible under 10X magnification. Flawless diamonds are incredibly rare because all naturally occurring diamonds will have inclusions. Shop a collection of diamond jewelry on 1stDibs.
  • 1stDibs ExpertApril 5, 2022
    It is impossible to say the exact number of Flawless diamonds that are in existence. However, diamonds with the Flawless clarity rating are extremely rare. This category consists of around only a half a percent of diamonds in existence. On 1stDibs, find an array of authentic Flawless diamond pieces.
  • 1stDibs ExpertFebruary 13, 2023
    Yes, flawless diamonds are more expensive than diamonds with imperfections. Flawless diamonds have no visible inclusions and the surface of these precious stones is free of blemishes. Flawless diamonds are considered to be rare and of higher quality, which renders them more valuable. The 4Cs, the grading system that was established by the Gemological Institute of America (GIA) in the 1950s, are the guidelines that determine how flawless diamonds are graded. Find diamond jewelry on 1stDibs.
  • An internally flawless diamond is a diamond that does not have any visible inclusions under a 10x magnification.
  • 1stDibs ExpertApril 5, 2022
    A D flawless diamond is a diamond gemstone of exceptional quality. Gems worthy of the title have the best possible color and clarity grades. Expert gemologists working in third-party laboratories provide the ratings for gemstones. Shop a range of diamond gemstone jewelry on 1stDibs.
  • 1stDibs ExpertOctober 12, 2021
    A cushion-cut diamond is a diamond with soft rounded edges — it draws on an old diamond shape and it combines a square cut with rounded corners. Cushion-cut diamonds, with their larger facets, are just as dazzling as their round-cut counterparts. Find a range of antique and vintage cushion-cut diamond jewelry on 1stDibs.
  • 1stDibs ExpertMarch 22, 2022
    A cushion cut diamond is one that has a square shape with rounded corners. It differs from the similarly shaped emerald cut in that it has a brilliant cut that maximizes sparkle rather than a stepped cut that shows off color and clarity. You'll find a variety of cushion cut diamond jewelry on 1stDibs.
  • 1stDibs ExpertOctober 5, 2021
    The best setting for a cushion-cut diamond depends on personal preference. The cushion cut is often referred to as a pillow cut due to its square or rectangular shape with rounded edges. This stone cut comprises 58 facets, like brilliant stones. The cushion cut has been popular since the 18th century. Browse a collection of cushion-cut diamond jewelry on 1stDibs.
  • 1stDibs ExpertFebruary 22, 2021
    Yes, cushion cut diamonds look larger than round cut diamonds. Cushion cut diamonds have a larger table per carat than round diamonds, making them appear larger. This coupled with cushion cut diamonds' larger facets, tend to make these types of diamonds appear larger to our eyes.
