Art Deco (1915-1935) received its moniker from the Exposition International des Arts Décoratifs et Industriels Modernes, held in Paris in 1925, which was largely dedicated to the jewelry arts. Emphasis was placed on the association of art and modern industry. Inspiration for this style was as far reaching as Oriental, African and South American Art and as varied as Cubism and Fauvism, both popular movements at the time. The term "Cubism" was often used to describe jewelry of this era because of the angles, geometric lines and figurative representations used in its execution. A desire to eliminate the flowing lines of Art Nouveau and distill designs to their rudimentary geometric essence, thus eliminating seemingly unnecessary ornament, resulted in the cleaner and more rigid lines employed in Art Deco jewelry. A look forward toward modernism and the machine age also featured prominently at this juncture in jewelry history.
During the Art Deco era, advancements in cutting techniques, including the advent of the modern round brilliant cut style, allowed for diamonds to become more dazzling and scintillating than ever before. Meanwhile, prosperity was permitting more people to afford diamond jewelry and engagement rings. New casting techniques further increased accessibility, as jewelers discovered more efficient ways to produce the most intricately detailed of settings.
All pearls originate in mollusks (mollusca), whether natural or cultured. Mollusks are a phylum of invertebrate animals that includes oysters, clams, mussels, snails and octopus among their approximately one hundred and twenty-eight thousand species, all with the ability to produce pearls. Only a few of these varieties can create gem quality pearls.
Rose Cut Diamond
The rose cut features a flat bottom with a dome-shaped crown, rising to a single apex. With anywhere from 3 to 24 facets, a rose cut diamond resembles the shape of a rose bud. The rose cut dates to the 1500s and remained common during the Georgian and Victorian eras.
Because of the softness of pure (24k), it is usually alloyed with base metals for use in jewelry, altering its hardness and ductility, melting point, color and other properties. Alloys with lower carat rating, typically 22k, 18k, 14k or 9k, contain higher percentages of copper or other base metals or silver or palladium in the alloy. Copper is the most commonly used base metal, yielding a redder color.
