Art Nouveau — generally considered to have begun in the late 1800s and ended with the start of World War I — was a movement in the decorative arts that drew inspiration from natural forms, such as trees, flowers and, of course, the human figure. The three main themes present in Art Nouveau jewelry and watches were flora, fauna and women.

Art Nouveau, which reached its pinnacle in the year 1900, spawned from artists who rejected the historicism of their predecessors to create an entirely new visual vocabulary. As compared to Art Deco jewelry’s geometric patterns and sharp lines, the extravagant style of antique Art Nouveau jewelry is characterized by curvilinear forms and whiplash lines, vibrant materials and dramatic imagery.

The first art and design movement of the 20th century, Art Nouveau was also a reaction against the Industrial Revolution, and took its inspiration from the theories of the Symbolists, the art of the Pre-Raphaelites, the ideas of John Ruskin and his follower William Morris and, most importantly Japanese crafts. (The country was a fertile ground for inspiration after it was opened to the West in 1854.) The Art Nouveau style touched all manners of the arts, including the most exultant jewelry.

Nature was a favorite muse for artists going back to the 18th and 19th centuries, but in the hands of 20th-century artists, it was depicted in new ways. For example, a withering flower was considered just as beautiful as one in full bloom. Winged creatures, such as insects and birds, were also a popular subject. Dragonflies and butterflies were particular favorites because they morphed so dramatically in different life stages.

This was also a reference to women, whose role in society was evolving. It was not uncommon to see a piece of jewelry that would at once reference a woman as a winged creature (think René Lalique’s famous Dragonfly brooch, circa 1897–98, at the Gulbenkian Collection in Lisbon). However, just as women’s roles were ambiguous, so was their image, as the femmes nouvelle were simultaneously eroticized and romanticized.

In addition to Lalique, vital figures in Art Nouveau jewelry included Louis Comfort Tiffany in the United States, Vladimir Soloviev, who designed jewelry for Peter Carl Fabergé in Russia, Fuset Grau of Spain, Karl Rothmuller of Germany and Philippe Wolfers of Belgium.

Art Nouveau jewelers used every “canvas” imaginable, looking beyond brooches and necklaces to belt buckles, fans, tiaras, dog collars (a type of choker necklace), pocket watches, corsages and hair combs. Multicolored gems and enamel could complete this vision better than diamonds. Jewelers also favored pearls, particularly baroque pearls, for their large size and irregular shape. However, opal was the most popular stone — its iridescence harmonized perfectly with the enamel, and it could be carved into any shape. Art Nouveau jewelry was primarily set in yellow gold.

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 rings, vintage engagement rings or Art Deco engagement rings.
