Īlthough very hard, topaz must be treated with greater care than some other minerals of similar hardness (such as corundum) because of a weakness of atomic bonding of the stone's molecules along one or another axial plane (whereas diamonds, for example, are composed of carbon atoms bonded to each other with equal strength along all of its planes). Mystic topaz is colorless topaz which has been artificially coated via a vapor deposition process giving it a rainbow effect on its surface. Typically, colorless, gray or pale yellow and blue material is heat treated and irradiated to produce a more desired darker blue. Naturally occurring blue topaz is quite rare. īlue topaz is the state gemstone of the US state of Texas. Some imperial topaz stones can fade on exposure to sunlight for an extended period of time. Many brown or pale topazes are treated to make them bright yellow, gold, pink or violet colored. Brazilian imperial topaz can often have a bright yellow to deep golden brown hue, sometimes even violet. Imperial topaz is yellow, pink (rare, if natural) or pink-orange. Orange topaz, also known as precious topaz, is the traditional November birthstone, the symbol of friendship, and the state gemstone of the US state of Utah. The pink and red varieties come from chromium replacing aluminium in its crystalline structure. A variety of impurities and treatments may make topaz wine red, pale gray, reddish-orange, pale green, or pink (rare), and opaque to translucent/transparent. Topaz in its natural state is a golden brown to yellow, a characteristic which means it is sometimes confused with the less valuable gemstone citrine.
This hardness combined with its usual transparency and variety of colors means that it has acquired wide use in jewellery as a cut gemstone as well as for intaglios and other gemstone carvings. It is one of the hardest naturally occurring minerals (Mohs hardness of 8) and is the hardest of any silicate mineral.
Topaz crystallizes in the orthorhombic system, and its crystals are mostly prismatic terminated by pyramidal and other faces. Topaz is a silicate mineral of aluminium and fluorine with the chemical formulaAl 2SiO 4(F, OH) 2.
