Why Gold Shines in Jewelry Craftsmanship

Gold is the feel-good metal, the serotonin of jewelry. Wear vintage and antique gold necklaces, watches, gold bracelets or gold rings and you feel happy, you feel dressed, you feel, well, yourself. 

Gold, especially yellow gold, with its rich patina and ancient pedigree going back thousands of years, is the steady standby, the well-mannered metal of choice. Any discussion of this lustrous metal comes down to a basic truth: Gold is elementary, my dear. Gold jewelry that couples the mystique of the metal with superb design and craftsmanship achieves the status of an enduring classic. Many luxury houses have given us some of our most treasured and lasting examples of gold jewelry over the years.

Since its founding, in 1837, Tiffany & Co. has built its reputation on its company jewelry as well as its coterie of boutique designers, which has included Jean Schlumberger, Donald Claflin, Angela Cummings and Elsa Peretti. There are numerous gold Tiffany classics worth citing. Some are accented with gemstones, but all stand out for their design and the workmanship displayed.

For the woman who prefers a minimalist look, the Tiffany & Co. twist bangle (thin, slightly ovoid) is stylishly simple. For Cummings devotees, signature pieces feature hard stone inlay, such as her pairs of gold ear clips inlaid with black jade (a play on the classic Chanel black and tan), or bangles whose design recalls ocean waves, with undulating lines of lapis lazuli and mother-of-pearl. And just about any design by the great Jean Schlumberger is by definition a classic.

Even had he eschewed stones and diamonds, Southern-born David Webb would be hailed for the vast arsenal of heavy gold jewelry he designed. Gold, usually hammered or textured in some manner, defines great David Webb jewelry. The self-taught jeweler made very au courant pieces while drawing inspiration from ancient and out-of-the-way sources — East meets West in the commanding gold necklaces made by Webb in the early 1970s. The same could be said for his endlessly varied gold cuffs.

In Europe, many houses have given us gold jewelry that sets the highest standard for excellence, pieces that were highly sought after when they were made and continue to be so. 

Numerous designs from Cartier are homages to gold. There are the classic Trinity rings, necklaces and bracelets — trifectas of yellow, white and rose gold. As a testament to the power of love, consider the endurance of the Cartier Love bracelet.

Aldo Cipullo, Cartier’s top in-house designer from the late 1960s into the early ’70s, made history in 1969 with the Love bracelet. Cipullo frequently said that the Love bracelet was born of a sleepless night contemplating a love affair gone wrong and his realization that “the only remnants he possessed of the romance were memories.” He distilled the urge to keep a loved one close into a slim 18-karat gold bangle. 

BVLGARI and its coin jewelry, gemme nummarie, hit the jackpot when the line launched in the 1960s. The line has been perennially popular. BVLGARI coin jewelry features ancient Greek and Roman coins embedded in striking gold mounts, usually hung on thick link necklaces of varying lengths. In the 1970s, BVLGARI introduced the Tubogas line, most often made in yellow gold. The Tubogas watches are classics, and then there is the Serpenti, the house's outstanding snake-themed watches and bracelets.

A collection called Monete that incorporated the gold coins is one of several iconic BVLGARI lines that debuted in the 1970s and ’80s, catering to a new generation of empowered women. Just as designers like Halston and Yves Saint Laurent were popularizing fuss-free ready-to-wear fashion for women on the go, BVLGARI offered jewels to be lived in. 

Since Van Cleef & Arpels opened its Place Vendôme doors in 1906, collection after collection of jewelry classics have enchanted the public. As predominantly expressed in a honeycomb of gold, there is the Ludo watch and accessories, circa the 1920s, and the golden Zip necklace, 1951, whose ingenious transformation of the traditional zipper was originally proposed by the Duchess of Windsor. Van Cleef's Alhambra, with its Moroccan motif, was introduced in 1968 and from the start its popularity pivoted on royalty and celebrity status. It remains one of VCA’s most popular and collected styles.

Mention must be made of Buccellati, whose name is synonymous with gold so finely spun that it suggests tapestry. The house’s many gold bracelets, typically embellished with a few or many diamonds, signified taste and distinction and are always in favor on the secondary market. Other important mid-20th-century houses known for their gold-themed jewelry include Hermès and Ilias Lalaounis.

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 rings, vintage 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.

    Whether a wedding band should be 14K or 18K depends on your personal preferences. Because it contains more pure gold, 18-karat gold will usually show off a richer color and be less likely to fade over time. On the other hand, 14-karat gold is less prone to scratching and damage because it has more alloy metals. Explore a large collection of gold wedding bands on 1stDibs.
  • 1stDibs ExpertApril 5, 2022
    Whether or not 18K gold wears off depends on how it's made. The finish will not wear off of a piece of jewelry or another object made entirely out of 18K gold.

You'll find a large selection of gold jewelry and decorative objects on 1stDibs.
  • 1stDibs ExpertMarch 22, 2022
    18K Italy gold is 18-karat gold produced in Italy. Karats tell you how much of a piece of metal is genuine gold. In the case of 18-karat gold, 18 parts are pure gold, and six parts are other metals. This makes 18-karat pieces 75 percent gold. You'll find a large collection of gold jewelry on 1stDibs.

Something made of 24-karat gold is 99.9% pure gold, while 18-karat gold items are 75% gold and 25% alloy metals. Generally, 18-karat gold is more durable and scratch-resistant due to the presence of alloy metals. On the other hand, 24-karat gold tends to be more richly colored and expensive. On 1stDibs, find a wide range of gold jewelry.
  • 1stDibs ExpertOctober 12, 2021

On 1stDibs, shop a range of vintage rose gold jewelry.
  • 1stDibs ExpertSeptember 16, 2024
    Yes, many people believe that 18k gold is worth buying. Due to the metal's durability, jewelry produced from 18-karat gold is often resistant to scratching and damage. In addition, the large amount of pure gold in the alloy gives white, rose and yellow 18-karat gold a vibrant color.

    On a watch, 18K gold means that the watch features genuine gold. An alloy, 18-karat gold is 75% pure gold and 25% other metals. The high gold content gives the metal an attractive color, while the alloy metals add strength to increase its durability. An 18-karat gold watch may be solid gold or gold-filled, which means it is primarily another metal that the watchmaker finished with a thin layer of 18-karat gold. On 1stDibs, find a large selection of gold watches.
  • 1stDibs ExpertDecember 5, 2024
    Many watch lovers believe that 18K gold is good for watches. An alloy, 18-karat gold is 75% pure gold and 25% other metals. The amount of gold makes the color of the alloy, whether it's white, yellow or rose, rich and visually appealing. At the same time, the addition of alloy metals increases the strength of the gold material. Explore a large selection of watches on 1stDibs.
  • 1stDibs ExpertAugust 29, 2024
    Yes, 18K 750 is real gold. Gold pieces that bear this hallmark are 18-karat gold, a 75% pure gold alloy and 25% base metal. One of the most popular materials for fine jewelry, 18-karat gold shows off a rich yellow, white or rose color and resists scratching more readily than pure gold. Explore a wide variety of 18-karat gold jewelry on 1stDibs.
  • 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 ExpertFebruary 22, 2021
    Yes, 18k gold can tarnish, but it is uncommon. Pure gold does not combine easily with oxygen and therefore does not tarnish. The higher the karat, the less likely a piece of gold will tarnish.
  • 1stDibs ExpertMarch 22, 2022
    Yes, 18-karat gold can turn green in some circumstances. This type of gold is about 75 percent genuine gold and 25 percent alloy, and the other metal or metals used to produce it may react negatively to acidic substances. When this occurs, 18-karat gold may take on a greenish hue. On 1stDibs, shop a large selection of gold jewelry.
