|Pure topaz is colourless, but it also occurs in a broad range of colours including yellow, blue, pink, peach, gold, green, red, and brown.|
Some natural yellow topaz is heated to become permanently pink. However, the natural intense pink and the sherry red shades are rare and sought-after.
Topaz sometimes has the amber gold of fine cognac or the blush of a peach and all the beautiful warm browns and oranges in between.

Blue Topaz is a clear vivid bluebell colour produced by irradiating and heating colourless topaz.
Topaz is an aluminium silicate and grows in crystalline form in granites and pegmatites. It contains up to 20% water or fluorine the proportion of each affecting the colour and shape of the gem.
The higher the water content the pinker or browner the colour and the longer the crystals. The higher fluorine content creates the colourless, yellow and pale blue shades and a squatter crystal shape.
Although topaz is the hardest silicate crystal, like diamond it cleaves easily along a direction parallel to the base of the crystal. Some gem quality crystals are huge and can weigh many kilos.
Blue topaz is readily available in 3 colours - sky blue, swiss blue and london blue. Sky blue topaz is a delicate pastel blue. A great example of this colour is our blue topaz necklace Judy. Swiss blue topaz is the most popular shade and has a fabulous saturated bright blue colour, the colour of a summer mediterranean sky. See our blue topaz pendants for excellent examples of swiss blue topaz. London blue is a darker slightly petrol blue.

The ancient Greeks believed that it had the power to increase strength and make its wearer invisible in times of emergency. Topaz was also said to change colour in the presence of poisoned food or drink. Did Livia know this?
Its mystical, curative powers waxed and waned with the phases of the moon: it was said to cure insomnia, asthma, and haemorrhages.
As topaz has a hardness of 8, keep your gems in separate boxes to protect other jewellery from scratches. Also avoid large temperature changes. Topaz often becomes paler if kept out in the sun.
Do not clean topaz in a home ultrasonic cleaner. The best way to clean topaz is in warm soapy water.
