The Legacy of Diamond in Jewelry Design

Antique diamond rings, diamond tiaras and dazzling vintage diamond earrings are on the wish lists of every lover of fine jewelry. And diamonds and diamond jewelry are primarily associated with storybook engagements and red-carpet grand entrances — indeed, this ultra-cherished gemstone has a dramatic history on its hands.

From “A Diamond Is Forever” to “Diamonds Are a Girl’s Best Friend,” pop culture has ingrained in our minds that diamonds are the most desired, the most lasting and the most valuable gemstone. But what makes the diamond so special? Each stone — whether it’s rubies, sapphires or another stone — is unique and important in its own right. April babies might claim diamonds for themselves, but just about everyone wants this kind of sparkle in their lives!

There are several factors that set diamonds apart from other stones, and these points are important to our gem education.

Diamonds are minerals. They are made up of almost entirely of carbon (carbon comprises 99.95 percent; the remainder consists of various trace elements). Diamonds are the hardest gemstones, ranking number 10 on the Mohs Hardness Scale. Even its name, diamond, is rooted in the Greek adamas, or unconquerable. The only object that can scratch a diamond is another diamond. Diamonds are formed deep within the earth at very high temperatures (1,652–2,372 degrees Fahrenheit at depths between 90 and 120 miles beneath the earth’s surface) and are carried up by volcanic activity. Diamonds are quite rare, according to the Gemological Institute of America, and only 30 percent of all the diamonds mined in the world are gem quality.

In the 1950s, the Gemological Institute of America developed the 4Cs grading system to classify diamonds: clarity, color, cut and carat weight. Not all diamonds are created equal (there are diamonds, and then there are diamonds). The value of the diamond depends on the clarity (flawless diamonds are very rare but a diamond's value decreases if there are many blemishes or inclusions), color (the less color the higher the grade), cut (how the diamond’s facets catch the light, certain cuts of diamonds show off the stone better than others) and carat weight (the bigger, the better).

When you start shopping for a diamond engagement ring, always prioritize the cut, which plays the largest role in the diamond's beauty (taking the time to clean your diamond ring at least every six months or so plays a role in maintaining said beauty). And 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

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 1920s Square Ring
  • 1stDibs ExpertNovember 21, 2023
    In the 1920s, engagement rings still looked like rings but were representative of a diverse range of styles and influences. Art Deco diamond ring designs took inspiration from the contemporary Cubist movement as well as from ancient Egypt – a revival sparked by the opening of King Tut’s tomb in 1922. Native American, African and Asian motifs also inspired jewelry pieces. Diamonds in square and rectangular shapes incorporating angular steps – like emerald cuts, Asscher cuts and baguettes – were set against black onyx, rubies, sapphires and emeralds to create color-blocking effects. Platinum, 18-karat gold, 14-karat white gold and sterling silver were some of the favored metals of the decade. Find a wide range of Art Deco engagement rings on 1stDibs.

    What 1920s furniture is called depends on its style. However, the most prominent design style of the decade was Art Deco. The term alone conjures visions of the Roaring Twenties, Machine Age metropolises, vast ocean liners, sleek typography and Prohibition-era hedonism. The iconic movement made an indelible mark on all fields of design throughout the 1920s and ’30s, celebrating society’s growing industrialization with refined elegance and stunning craftsmanship. Art Deco furniture often featured bold geometric lines, floral forms, shimmering mirrored finishes, sleek metal accents, and the use of expensive materials such as shagreen or marble as well as exotic woods such as mahogany, ebony and zebra wood.

    The clothing style in the 1920s that most people think of first is the flapper style. Women who dressed in this style sported loose-fitting, short dresses, often outfitted with drop waists and fringe. Small cloche hats and headbands were signature accessories of the flapper look. During the decade, pleated tennis skirts and cardigan sweater sets left the courts and became staples of some women's everyday styles. For men, soft collars replaced stiff, starched ones, and simple single and double-button suit jackets worn without waistcoats became trendy. Trousers also took on a new shape with wider-cut legs, and Oxford bags gained popularity. On 1stDibs, shop a variety of 1920s apparel and accessories.

    The iconic dresses from the 1920s are called flapper dresses. This name comes from the term flapper, which was used to describe young women during the period who enjoyed personal fulfillment and independence in American cities, particularly as they gained the right to vote and enjoy other freedoms previously reserved for men. Flappers danced at jazz clubs and upended most societal restrictions placed on women at the time, and fashion statements typically attributed to flappers included short “bob” haircuts, higher hemlines and other then-audacious style choices.

    Coco Chanel was considered one of the leading fashion designers in the 1920s and ’30s in Paris. The first Chanel shop was established in 1910 on rue Cambon by the young milliner Gabrielle Chanel, who had picked up the nickname “Coco” while working as a club singer. The boutique drew the attention of the Parisian fashion elite, who popularized her wide-brimmed Chanel Modes hats. Soon, she added a sportswear store in the Normandy resort town of Deauville, where Coco set the tone for her defining sense of style — traditionally masculine garments reimagined for feminine shapes, made from simple jersey fabric. Effortless and elegant, Chanel's designs promoted comfort and grace in women’s wear that had been dominated in the previous century by complicated layers of fabric and cumbersome corsets. She followed this success with a couture house, opened in 1915 in Biarritz. In 1926, Chanel introduced her first little black dress, reclaiming a color that had once been reserved for mourning and working-class women. That same decade, she debuted her perfume, Chanel No. 5, as well as the Chanel suit with a fitted skirt, inspired by the boxy lines of men’s clothing and employing a sporty tweed. During the 1920s, she also unveiled the predecessor for the 2.55 Flap bag, which remains one of Chanel's most popular offerings.

    What wedding rings looked like in the 1800s was similar to other Victorian jewelry. The Victorian era spanned from 1837 to 1901, coinciding with the reign of Queen Victoria in the United Kingdom. At the beginning of this period, rings were made of gold and affordable only to the wealthy. Designs for Victorian-era rings often featured repoussé work and chasing, in which patterns are hammered into the metal. Some featured stones secured by collets, settings similar to bezels, with prongs and a closed back. On 1stDibs, find a selection of Victorian wedding rings.

    In the early 1900s, engagement rings often looked like other jewelry from the Edwardian era, which coincided with the reign of King Edward VII in the United Kingdom from 1901 to 1910. Cutters used new diamond saws and jewelry lathes to refine the old European cut. The resulting stones, designed to sparkle in the light from candles and gas lamps, are beloved by connoisseurs for their inner fire and romantic glow. The invention of the oxyacetylene torch enabled jewelers to use platinum, which had previously been too challenging to work with. This technological advancement made it possible for Edwardian rings to show off lacy filigree and milgrain work. Nature also influenced jewelry in the early 1900s. Flowing and floral garland motifs were so popular that the Edwardian age is sometimes called the "garland era." Find a selection of Edwardian engagement rings on 1stDibs.
