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.

Today, antique and vintage bracelets are versatile and universally loved accessories that can add polish and pizzazz to any ensemble.
Bracelets were among the jewels discovered to have been buried with Pharaoh Tutankhamun when his tomb was unearthed in 1922, and wrist and arm bracelets were allegedly worn by Queen Puabi in Sumer, southern Mesopotamia. But preceding the adornments of Ancient Egypt and elsewhere, the people of prehistoric times likely wore the decorative accessory, fashioning it from shells and fish bones. When the Bronze Age allowed for more durable materials and semiprecious stones to be incorporated into jewelry, bracelets became a treasured symbol of wealth.
In the thousands of years following the debut of the world’s first bracelets, the artistry behind this common accessory has only broadened, with designers at popular jewelry houses growing more venturesome over time. David Webb looked to nature for his Animal Kingdom bracelets, and for her best-selling bracelets and more at Tiffany & Co., Elsa Peretti would frequently do the same. From bangles to tennis bracelets, the modern age offers plenty of options.
Internationally acclaimed bracelet designs have on occasion become powerful symbols of status, style and, in the case of Cartier's iconic design, love. The Cartier Love bracelet can be found on the wish list of most jewelry lovers and on the wrist of some of the world’s biggest stars. Its arrangement of mock screwheads and distinctive functionality — it was initially locked and unlocked with an accompanying vermeil screwdriver — is an enduring expression of loyalty, unity and romance. (Do you know how to spot a fake Cartier Love bracelet?)
While the Love bracelet has played a role in the skyrocketing popularity of cuff-style bracelets, they are far from the only glamorous option for collectors. Make a statement with an Art Deco design, a style that sees all kinds of iterations fitted with studded cuffs, one-of-a-kind shapes and dazzling insets. A chunky vintage gold bracelet in the Retro style will prove eye-catching and elevate any outfit.
One of the best things about bracelets, however, is that you never have to choose just one. Style icon Jacqueline Kennedy stacked her Croisillon bracelets — designed by Jean Schlumberger for Tiffany & Co. — with such frequency that the ornate bangles were eventually dubbed “Jackie bracelets” by reporters. Contemporary silver pieces can easily complement each other, rendering a layering of luxury almost a necessity.
Find a diverse collection of bracelets that you can sort by style, stone cut and more on 1stDibs.
This iconic jewel has captured countless hearts with its elegant design and its amatory symbolism. Counterfeiters have taken note of the demand and created fake versions. If you’re looking for a genuine Cartier Love bracelet, it’s crucial to check all the elements for authenticity. Our guide will teach you the telltale traits of a knockoff.
