Black tourmaline (also called schorl) is most often recommended for protection, grounding, and purification. The structure of this mineral emphasizes directionality and change. It can be used to break up stagnant energy and encourage us to reconnect to the Earth. Black tourmaline facilitates self-discovery and strengthens our resolve to heal past hurts and old conditioning.
"Black tourmaline is a powerful tool for honing your inner strength and staying grounded in a busy world." - by Nicholas Pearson
