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.
Diamonds with this cut possess a squarish girdle with gently rounded corners. Old mine cut diamonds have a high crown, a small table, and a large, flat culet. They are similar to today's cushion cut. The old mine cut dates to the 1700s and was most prevalent during the Georgian and Victorian eras.
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.
Onyx is the name for the black and white banded variety of chalcedony. It has been used since antiquity when it was highly prized as a cameo stone. The layered color structure allows the engraver to cut the subject in one color while creating a background of another. The term onyx is often encountered describing pure black material although this is technically incorrect.
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.
