Raw Black Tourmaline

A strong all-round protective stone, Black tourmaline is something that you must have in your collection. This black protection stone is possibly the best crystal for deterring lower frequencies and energies or promoting a more positive outlook towards emotions.
What makes black tourmaline a very effective crystal for protection is its ability to transmute negative energy into positive. It functions as a shield of spiritual energy surrounding you, to steer away from negative thoughts and feelings from other people.
The black tourmaline protection stone also safeguards you against ill-wishers and poor attitudes by stimulating the link between the root chakra and earth, thereby cleaning up stagnant energy within your surroundings.
