A Close Look at Art-deco Jewelry

Fascination with the Jazz Age is endless, and even today jewelry designers continue to be inspired by authentic Art Deco jewelry and watches.

The Art Deco period, encompassing the 1920s and ’30s, ushered in a very distinct look in the design of jewelry. There were many influences on the jewelry of the era that actually began to take shape prior to the 1920s. In 1909, Serge Diaghilev brought the Ballet Russes to Paris, and women went wild for the company’s exotic and vibrant costumes It’s no wonder, then, that jade, lapis lazuli, coral, turquoise and other bright gemstones became all the rage. There already existed a fascination with the East, particularly China and Japan, and motifs consisting of fans and masks started to show up in Art Deco jewelry.

However, the event that had the greatest influence on Deco was the excavation of the tomb of King Tut in 1922. When the world saw what was hidden in Tut’s burial chamber, it sent just about everyone into a frenzy. Pierre Cartier wrote in 1923 that “the discovery of the tomb will bring some sweeping changes in fashion jewelry.” And he couldn’t have been more right. “Egyptomania” left an indelible mark on all of the major jewelry houses, from Cartier to Van Cleef & Arpels, Boucheron and Georges Fouquet. (Cartier created some of the most iconic jewelry designs that defined this era.)

While a lot of Art Deco jewelry was black and white — the black coming from the use of onyx or black enamel and the white from rock crystal and diamonds — there is plenty of color in jewelry of the era. A perfect accent to diamonds in platinum settings were blue sapphires, emeralds and rubies, and these stones were also used in combination with each other.

Many designers employed coral, jade and lapis lazuli, too. In fact, some of the most important avant-garde jewelers of the period, like Jean Després and Jean Fouquet (son of Georges), would combine white gold with ebony and malachite for a jolt of color.

A lot of the jewelry produced during this time nodded to current fashion trends, and women often accessorized their accessories. The cloche hat was often accented with geometric diamond brooches or double-clip brooches. Backless evening dresses looked fabulous with sautoir necklaces, and long pearl necklaces that ended with tassels, popular during the Edwardian period, were favored by women everywhere, including Coco Chanel.

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
