TOPAZ: Topaz is a stone of strength.
Color: Pure topaz is colorless, but it also occurs in a broad range of colors: yellow, blue, pink, peach, gold, green, red, and brown.
Some natural yellow stones are heated to become permanently pink (pinked topaz).
Description: Topaz is an aluminum fluorite silicate containing fluorine and has a chemical formula of Al2F2SiO4. It is one of the few gem minerals which, under suitable conditions, grow into enormous crystals. Topaz typically occurs in cavities in rhyolites and granite, in pegmatite dikes, and in high-temperature veins with cassiterite and tourmaline.
The stone is transparent with a vitreous luster. A light yellow, brown and pink variety of topaz are valued as a gemstone. The pure crystals of topaz used a great deal in jewelry.
