Although this has not been conclusively proven, topaz is said to take its name from the island Zabargad, formerly known as Topazos, the site of the oldest known peridot mine. The pink to red colour range tends to be more expensive than the other colour ranges, but when a stone in the yellow to orange range is intensely coloured and has a pink or reddish overtone, the stone is referred to as imperial topaz, which is the most expensive variety.
Naturally coloured blue topaz does occur, and due to its rarity was historically considered one of the most expensive colours, in particular the London blue, which is a very dark, velvety blue. This lasted until the discovery was made that colourless or weekly coloured brown topaz could be treated with heat or irradiated to produce a variety of blues. Ever since, artificially coloured blue topaz has dominated the market, and sky blue has become the colour most customers associate with this gem.
Topaz is quite hard, and therefore its colourless varieties make excellent diamond alternatives in designs that call for large white stones.
Topaz is sensitive to chemicals and heat, especially exposure to sunlight, and care should be taken when storing this gem to avoid changes in colour and appearance.
Please note: We take great care to ensure that the photographs are an accurate representation of the actual stone, but due to differences in screen quality and resolution, and the fact that the colour of a gemstone is dependent on the type of light it is viewed in, some variation is possible.
