In ancient Greece topaz was believed to give strength to the wearer.
Until the 1950's topaz was thought of almost exclusively as a golden-green gemstone. It was often confused with peridot during the development of modern mineralogy, with its name originating from island of Zabargad. This island was once called 'Topazios' by the Ancient Greeks and was famed as a source of beautiful green gems.

The most highly prized topaz gemstone is imperial topaz which is a reddish-orange colour. Ownership of this particular type of topaz was once restricted to the Russian Royal Family during the time where the Ural Mountains in Russia were the only source of Imperial Topaz.

Some cultures once believed that wearing a topaz about the heart promised long life, beauty and intelligence.
One of the largest flawless topaz gemstones has recently gone on display at The Natural History Museum in London. It weighs 9,381cts (approximately 2 kilos) by British explorer Max Ostro in Minas Gerais, Brazil.

In nature topaz is mainly found in a colourless form.

Some topaz can show different colours when viewed from different directions. This is a quality in the structure of the gemstone known as pleochroism. Magical!
