One of the most popular topaz gemstones, Swiss blue topaz is an electric, vivid blue said to rival the incredible hues of the sea. The stone is naturally flawless in most cases. 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 a orthorhombic structure with crystals that are usually primatic. 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.
