Key Tourmaline Gemstone Details
Tourmalines belong to an isomorphous series, which means they encompass a wide range of chemical compositions and colours. They exhibit a vitreous lustre that varies from transparent to opaque and can display multiple colours within a single stone.
Common tourmaline colour names include:
- Rubellite (red)
- Indiclite (dark blue)
- Paraiba (electric blues to neon greens)
- Watermelon (multicoloured pink and green)
Frequent Tourmaline Treatments
Heat treatment or irradiation may be used to enhance the colour of tourmaline. Green and blue gemstones can be brightened by heat treatment, while some red shades can be intensified through irradiation.
Employ dichroscopes and refractometers to differentiate tourmaline from visually similar materials.
