- Tourmaline is a crystalline boron silicate mineral with elements such as aluminium, iron, magnesium, sodium, lithium or potassium

- Watermelon Tourmaline is a naturally formed bi-colour gemstone with either a red/pink centre with a surrounding green layer or vice versa
- Tourmaline translates to ‘Turamali’ meaning ‘stone of mixed colours’
- Pyroelectricity - Tourmaline becomes electrically charged when it is heated
