During the Late Victorian or Aesthetic period (1885-1900), jewelers used diamonds and feminine, bright gemstones such as sapphire, peridot, and spinel. Star and crescent designs as well as elaborate hat pins were also popular. Some scholars believe the aesthetic era began sooner, in 1875, and ended as early as 1890.
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.
