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.

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.
