Understanding Tourmaline Gemstones
Tourmalines belong to an isomorphous series, which means they exhibit a range of chemical compositions and colours. These versatile gemstones can display multiple colours within a single stone and can be cut to emphasize their unique hues.
Featuring a vitreous lustre, tourmalines can range from transparent to opaque in appearance.
Various Types of Tourmaline
- Rubellite - red
- Indiclite - dark blue
- Paraiba - electric blues to neon greens
- Watermelon - multicoloured pink and green
Common Enhancement Treatments
The colour of tourmaline can be improved through heat treatment or irradiation. Green and blue gemstones may be lightened using heat treatment, while red shades can be intensified through irradiation.
Using dichroscopes and refractometers can help differentiate tourmalines from visually similar materials.
