This natural white topaz stone features the Natural Brilliance Cut created by Swarovski Gemstones™. Its precision-cut, finely calibrated facets are designed to maximize the radiant light within the gemstone. In comparison to the cut typically used for topaz, the Natural Brilliance Cut delivers superior brightness, fire, reflection and the dispersion effects that generate eye-catching rainbow colors.
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 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.
The oval cut is an even, symmetrical shape but elongated. The arrangement of its facets is similar to that of a round brilliant, designed to maximize light and color.
