Featuring a striking kite shape, this Swiss-blue topaz is a great choice for your custom designs. 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 gemstone 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 gemstones, making it an economical alternative to more costly gems. 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 give the gemstone color. Gemstones 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 gemstone is believed to dispel sadness and fear, to ward off poisons and to reverse infertility. A revival from the 1920s, the kite cut features four sides and a large table that enhances the brilliance of the gemstone.
