Topaz is a silicate mineral of aluminium and fluorine with
the chemical formula Al2SiO4(F, OH)2.
Topaz crystallizes in the orthorhombic system, and its crystals are
mostly prismatic terminated by pyramidal and other faces. It is one of the
hardest naturally occurring minerals (Mohs hardness
of 8) and is the hardest of any silicate (i.e., silicon-based)
mineral. 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 intagliosand other gemstone carvings.
