08Nov Topaz – a “common” Gemstone of Uncommon Beauty
Topaz is a very attractive gemstone, which comes in many different colours including blue, pink, red, yellow, brown and colourless. Colourless and yellow topaz are fairly “common” gem materials which can be found in many countries across the world.
In crystal form, topaz can be very large compared to some other gemstones. It is therefore not unusual to see relatively big, cut and polished topaz in pieces of jewellery or simply displayed as examples of natural beauty. A famous cut topaz is the Chalmers Topaz, which weighs 5899.5 carats and is on display at the Field Museum in Chicago.
Blue topaz is one of the most popular commercial gemstones, both due to its stunning colour and also its affordability. Even large, blue topaz can be purchased relatively cheaply.
Buyers should be aware that the majority of blue topaz is treated to enhance its colour (usually with heat or radiation). Blue topaz is commonly created from colourless topaz, but it is also possible to use blue or even yellow topaz as the base material. Whilst this is standard practice within the industry, any treatment of a gemstone should be disclosed to a potential purchaser.
Topaz has a high hardness (it has a rating of 8 on the Mohs Hardness Scale) and can therefore be given a high degree of polish in order to enhance its beauty when set in a piece of jewellery. Topaz is a versatile stone which is often seen in pendants, bracelets and earrings, as well as rings for special occasions.
It is believed that topaz can help to reduce stress and promote a sense of calm and tranquillity, so it may benefit people who have been suffering from depression or unusually high levels of stress. The stone is also said to encourage a positive outlook and aid recovery from a shock or trauma.
Topaz is the birthstone for people born in November.
