Black Tourmaline is a protective stone that is said to shield against ill-wishing and negative energies. In addition it is believed to protect against electromagnetic radiation from mobile phones.
Tourmaline can be used as a natural insecticide. When buried in the ground or earth around a plant it is believed to deter pests and encourage healthy growth.
Tourmaline is said to encourage a positive attitude to life, whatever the circumstances, dispelling negative thoughts and encouraging clear rational thought processes.
