Topaz gemstones have an exceptionally wide color range. Topaz is most commonly found in golden-browns to yellows, which means it is sometimes confused with the less valuable gemstone, citrine. Topaz can also be found in various tones and saturations of blue, green, orange, red, pink, and even purple. The color varieties are most often identified simply by their hue, i.e. blue topaz, pink topaz, etc. There are a few special trade names in the topaz family:
- Imperial topaz is a medium reddish-orange to orange-red and is one of the most expensive colors.
- Sherry topaz (sometimes called “precious topaz”) is a yellowish-brown to orange.
- Mystic topaz is a colorless topaz which has been artificially coated via a vapor deposition process giving the surface a rainbow effect.
- Naturally occurring Blue topaz is quite rare. Colorless, gray, or pale yellow material can be heat treated and irradiated to produce a more attractive darker blue.
