    • n topaz A mineral of a vitreous luster, transparent or translucent, sometimes colorless, often of a yellow, white, green, or pale-blue color. It is a silicate of aluminium in which the oxygen is partly replaced by fluorin. The fracture is subconchoidal and uneven; the hardness is somewhat greater than that of quartz. It usually occurs in prismatic crystals with perfect basal cleavage, also massive, sometimes columnar (the variety pycnite). Topaz occurs generally in granitic rocks, less often in cavities in volcanic rock as rhyolite. It is found in many parts of the world, as Cornwall, Scotland, Saxony, Siberia, Brazil, Mexico, and the United States. The finest varieties are obtained from the mountains of Brazil and the Ural Mountains, Those from Brazil have deep-yellow tints; those from Siberia have a bluish tinge; the Saxon topaz has a pale wine-yellow. The purest topazes from Brazil, when cut in facets, closely resemble the diamond in luster and brilliance.
