Topaz is a fluorine aluminium silicate and comes in yellow, yellow-brown, green, blue, light blue, red and pink colours. Sometimes it is also colourless.

The gemstone has been known for around 2000 years and is one of the so-called apocalyptic stones that are intended to serve in protection against enemies. It is also known as a symbol of beauty and splendour.

It cannot be proved conclusively whether the name of Topaz comes from the Sanskrit or the Greek, though the Greek name 'topazos' means 'green gemstone'. The Romans, however, dedicated Topaz to Jupiter.

The colour in which Topaz is most commonly found is yellow. In the 18th century, it was mined in Saxony, Germany for a period of over 60 years, however, most of the crystals were less than 10mm in diameter. In contrast, Topaz crystals as large as 100mm in diameter can be found in Siberia and Brazil

In mysticism, Topaz is attributed with a cooling, styptic and appetising effect. It is said to dispel sadness, anger and nocturnal fears, to warn its wearer of poisons and protect him or her from sudden death. It is reputed to make men handsome and intelligent and sterile women fertile and happy.
