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.
Enameling is a decoration technique in which a glass of certain composition is fused to the surrounding or under laying metal. Although the exact origins are unknown, the art of enamelling has been practiced since ancient times. The favor of adorning jewelry with bright colors has always existed and the use of glass created colors which nature – in the form of gemstones – could not provide for in ancient times. Excavations on Cyprus – in the Mediterranean – in the 1950's brought cloisonné enameled jewelry to the surface which dates from the 13th and 11th century BC. These are, to date, the earliest enameled items found in this particular technique.
Silver is a white metallic element, harder than gold, softer than copper and second only to gold in malleability and ductility. Represented on the Periodic Table of the Elements by the symbol Ag, silver is an excellent conductor of heat and electricity. Silver is considered one of the noble metals because of it is excellent resistance to oxidation. Historically, silver has played a prominent role in the production of jewelry an objets d'art and is usually alloyed with another metal to harden it enough to maintain the desired shape and details imparted to it.
