Tourmaline Gemstone Overview
Tourmalines belong to an isomorphous series, which means they exhibit a broad range of chemical compositions and colours. Their vitreous lustre varies from transparent to opaque, and some gems display multiple colours.
Common tourmaline colour names include:
- Rubellite (red)
- Indiclite (dark blue)
- Paraiba (electric blues to neon greens)
- Watermelon (multicoloured pink and green)
Usual Tourmaline Treatments
Colour improvements in tourmaline may involve heat treatment or irradiation, which can enhance green and blue gemstones or intensify red shades.
Use dichroscopes and refractometers to distinguish tourmaline from similar-looking materials.
