Topaz ( TOH-paz) is a silicate mineral of aluminium and fluorine with the chemical formula Al2SiO4(F, OH)2. It is used as a gemstone in jewelry and other adornments. Common topaz in its natural state is colorless, though trace element impurities can make it pale blue, golden brown to yellow orange. Topaz is often treated with heat, or radiation to make it a deep blue, reddish-orange, pale green, pink, or purple.
Topaz is a nesosilicate mineral. It is one of the hardest naturally occurring minerals, and has a relatively low index of refraction. It occurs in many places in the world.
