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 Ruby in Jewelry Design

This deep red gem is the color of heat and passion — vintage and antique ruby jewelry is perfect for those born in the middle of summer.

Rubies are one of the few gemstones that can give diamonds a run for their money. Just consider the Van Cleef Arpels “scarf” necklace the Duke of Windsor presented to the Duchess on her 40th birthday, in 1936 — set with diamonds and dripping with rubies, a testament to the deep-red gemstone’s power — or the slippers encrusted with 4,600 rubies that Harry Winston made to commemorate The Wizard of Oz’s golden anniversary. July babies have permission to adorn themselves with this beautiful red stone even when it’s not their birthday.

Rubies are considered precious stones — along with diamonds, sapphires and emeralds — and have a hardness of 9.0 on the Mohs Scale, surpassed only by Moissanite and diamonds. They are composed of corundum, a colorless mineral that is also the basic material of sapphires. In the July birthstone, the red of the gemstone — and the various hues seen in sapphires — are produced by the presence of trace elements. In the case of a ruby, this element is chromium. Rubies range in color from vermilion to a violet red. They are also pleochroic, which means that a stone’s hue can vary depending on the direction of viewing. The most sought-after color is pigeon’s blood: pure red with a hint of blue.

Rubies that are hosted in dolomite marble are the most prized: Because the marble is low in iron, so are the rubies, resulting in a more intense color. Rubies found in basalt, which has a higher iron content, are generally darker and less intense.

When shopping for antique and vintage ruby jewelry, remember that the 4Cs of selecting the perfect diamond — color, clarity, cut and carat — also apply to rubies.

According to the Gemological Institute of America, the color of the July birthstone should be a vibrant to slightly purplish red, and the stone should be clear and inclusion-free. Accordingly, the cut should show off its color and clarity. As for the last criterion, fine rubies more than a carat in weight are rare. Often, large rubies are more expensive than diamonds of comparable weights.

Questions About Ruby 18k Gold Heart
  • 1stDibs ExpertApril 5, 2022
    18K green gold is an alloy created by mixing silver, copper and zinc with normal gold. 18K green gold is greener than 14K green gold. On 1stDibs, shop a wide collection of genuine 18K green gold from some of the world's top sellers.
  • 1stDibs ExpertFebruary 22, 2021
    Yes, 18k is the perfect karatage for jewelry. While 24k is more prized and typically more expensive, it is also less dense and durable than 18k gold.
  • 1stDibs ExpertApril 5, 2022
    Yes, 18K gold is real gold. However, it is not pure gold. Something marked 18K is 75 percent genuine gold and 25 percent metal alloy. On 1stDibs, shop a range of expertly vetted gold jewelry from some of the world’s top sellers.
  • 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. However, wear can occur on pieces that feature 18K gold plating, a thin layer of gold applied over another type of metal. You'll find a large selection of gold jewelry and decorative objects on 1stDibs.
  • 1stDibs ExpertApril 5, 2022
    An 18K gold watch is a timepiece made from gold precious metal of a specific purity. The term 18K means 18-karat, a precious metal that is 75 percent pure gold and 25 percent alloy. Shop a large collection of gold watches 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.
  • 1stDibs ExpertAugust 26, 2024
    The difference between 24K gold and 18K gold is how much pure gold the metals contain. 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 ExpertApril 5, 2022
    Yes, gold dipped, also known as gold plated, pieces are considered real gold. The process coats a piece of metal or alloy with a layer of gold for a gold finish. Shop a collection of 18 karat gold jewelry, solid and dipped, 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.

    How much your 18K gold chain is worth depends on several factors. As a material, 18-karat gold typically fetches a higher price than 14-karat and 10-karat gold on the scrap market because it contains more pure gold. When selling a piece for scrap, the length, thickness and weight of your chain will determine how much you can expect to receive for it.
