White Topaz Round Rose-Cut Cabochons


This round rose-cut white topaz is a great choice for designs that call for a hard white stone with a vintage look. The bright-white color means that it is complements nearly any stone. White topaz is valued for its brilliant white color and economical price. Because it is a natural stone, it may contain natural impurities and presents a level of fire more similar to that of a diamond than does a lab-created stone. This faceted stone offers a bright, eye-clean clarity. Topaz is one of the birthstones for November.

A hard, usually transparent aluminum silicate gem material, faceted topaz has a brilliance that rivals more expensive stones, making it an economical alternative to more costly gemstones. An "8" on the Mohs scale, topaz is tough and durable, ideal for all types of jewelry. Topaz forms in an orthorhombic structure with crystals that are usually prismatic. Pure topaz is colorless; impurities in the stones give them the colors they present; stones can appear in a range of colors, with natural pink being the rarest. Most topaz colors are heat-treated or irradiated to enhance their color. In folklore, this stone is believed to dispel sadness and fear, to ward off poisons and to reverse infertility.

A favorite of yesteryear, this rose-cut faceting features a flat base (no pavilion) and a crown made up of triangular facets.
