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.

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

Questions About Star Set Diamond
  • 1stDibs ExpertJanuary 23, 2024
    A star-cut diamond is a diamond with a certain shape and facet arrangement. Specifically, the style features 86 facets and is a brilliant cut that shows off the sparkle of a diamond.

  • 1stDibs ExpertApril 5, 2022

  • 1stDibs ExpertApril 5, 2022
    An illusion diamond setting helps to enhance the size of the stone. The precious metal the ring is made from is intricately designed around the diamond. From a distance, this makes the diamond itself appear much larger. Shop a collection of illusion-set diamonds from some of the world’s top sellers on 1stDibs.

    Whether Cartier will set a loose diamond depends on the circumstances.

  • 1stDibs ExpertSeptember 28, 2021
    The best setting for a solitaire diamond is the prong setting. In such a setting, the stone is held in place with a minimal amount of metal allowing more light to pass through the diamond resulting in added brilliance. Find a collection of solitaire diamond jewelry on 1stDibs.
  • 1stDibs ExpertOctober 12, 2021
    One of the best settings for oval diamonds is the prong. The most frequent and classic setting type, it exposes the majority of the diamond and lets more light penetrate, increasing its brightness and shine.
  • 1stDibs ExpertApril 5, 2022
    The difference between pavé and channel set diamonds is the setting. On pavé jewelry, tiny beads or prongs hold the individual gemstones in place. Channel settings are deep grooves that hold diamonds, eliminating the need for prongs or beads. Shop a large collection of diamond gemstone jewelry on 1stDibs.
  • 1stDibs ExpertOctober 19, 2021
    A marquise-cut diamond looks great in a variety of settings, but you should choose one that protects the center stone. Some of the top marquise diamond ring settings are bezel, prong and halo. Find a variety of marquise-cut diamond rings on 1stDibs today.
  • 1stDibs ExpertOctober 5, 2021
    The best setting for an emerald-cut diamond is a matter of personal preference. For emerald-cut diamonds, solitaire and pavé settings are popular. The emerald cut comprises 58 facets and truncated corners on a rectangular step-cut stone. The flat pavilion of an emerald-cut diamond can magnify the stone’s imperfections, so the gem’s clarity is key. Initially a popular cut for emeralds only, it is now used on other precious stones, but the name has come to define the style. Find antique and vintage emerald-cut diamond jewelry on 1stDibs.
  • 1stDibs ExpertDecember 4, 2023
    There is no single best setting for a diamond tennis necklace. You can find tennis chains with both prong and bezel settings, and both types can keep diamonds secure when they are well crafted. The biggest difference is that full bezel settings encircle the gemstones, while prongs hug the stones with three or four metal elements, leaving most of their edges visible. Feel free to choose the type of setting that appeals most to you. On 1stDibs, explore a wide range of diamond tennis necklaces.
  • 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.

    Most experts agree that a prong setting is best for diamond stud earrings. Prongs help keep diamonds securely in place.

For diamond stud earrings with weights of 2 carats or more, a six- or eight-prong setting can increase stability and security. Explore a large selection of diamond stud earrings on 1stDibs.
