Offering a delightful warm color, this precious topaz offers a slight color range of light, medium and dark golden hues. Highlight the vibrant color by using the gemstone in a custom design or partner it with complementary-color gems for a multicolor look. 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. The cushion cut is a classic style; it combines features of the oval cut with a deep cut and large facets.
