Topaz occurs inside a variety of colours: deep golden yellow topaz (sometimes called sherry topaz) and pink topaz would be the best; blue and green stones will also be popular. Natural pink stones are rare - most pink topaz is heat-treated yellow material. Much colourless topaz is irradiated and heat-treated to a variety of blues, some almost indistinguishable from aquamarine when seen naked with eye. Some topaz has tear-shaped cavities, containing a gas bubble or several immiscible (non-mixing) liquids. Other inclusions for example cracks, streaks, and veils also occur. Prismatic topaz crystals possess a characteristic lozenge-shaped cross-section and striations parallel for their length. Topaz has one perfect cleavage.
Topaz happens in igneous rocks for example pegmatites, granites, and volcanic lavas. It can also be present in alluvial deposits as waterworn pebbles. Localities include Brazil, the united states, Sri Lanka, Burma, the first kind USSR, Australia, Tasmania, Pakistan, Mexico, Japan and Africa. Brazil, Pakistan and Russia are causes of pink topaz.
Within the 17th century the Braganza diamond (1,640 carats) within the Portuguese crown was regarded as the biggest diamond ever found. It was never confirmed which is now believed to possess been a colourless topaz. The name “topaz” is regarded as based on the Sanskrit word “tapas”, meaning fire.
