A Kaleidoscope of Colours: Topaz Gemstones

Topaz gemstones come in a variety of colours, ranging from transparent to translucent, and exhibit a brilliant vitreous lustre. Topaz is the November birthstone and the zodiac gemstone for Scorpio. With a hardness of 8, topaz is a durable gemstone that is believed to promote good health when present in a home.

Topaz Treatments and Testing

Topaz may undergo heat and irradiation treatments to alter its colour, and coatings can be applied to produce green shades and optical effects. Dichroscopes and Chelsea colour filters can assist in identifying topaz gemstones.
