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.
The most popular form of sapphire is blue sapphire, which is known for its medium to deep blue colour and strong saturation. Fancy sapphires of various colours are also available. In the United States, blue sapphire tends to be the most popular and most affordable of the three major precious gemstones (emerald, ruby, and sapphire).
Single Cut Diamond
A single cut diamond has a large table and an octagonal girdle. The culet, or bottom edge of the diamond, may be pointed or it may be flat. A single cut diamond usually has 18 facets. The single cut is an extremely old diamond cut dating to the 1300s.
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.
The element platinum derives its name from the Spanish Platina del Pinto which translates to 'little silver from the Pinto' (said to be a river near Popayan, Columbia in which alluvial platinum was first found by the Spanish Conquistadors). Its white metallic luster leaves little doubt as to why the Spanish chose the name.
Platinum belongs to a group of elements, fittingly called the platinum group of metals. Apart from platinum the group comprises Osmium, Iridium, Palladium, Rhodium and Ruthenium. Platinum is often found as natural alloys containing one or more of these other elements and it wasn't until 1804 that all but one of the elements were isolated and named.
Platinum is malleable, ductile and very strong. In addition, it does not tarnish and it doesn't corrode making it a highly prized metal and extremely suitable for the manufacture of fine jewelry.
