Black Tourmaline is believed to be one of the powerful protective and grounding stones. It’s thought to shield from negativity, both from external and internal sources. It may also be used to cleanse a space, as Black Tourmaline is said to absorb dangerous energies and transmute them into harmless, even pleasant, feelings. This stone is said to be especially helpful to those dealing with particularly emotionally taxing matters. Black Tourmaline is also believed to give inner strength, and provide calming energy. This stone resonates most strongly with the Root chakra, but may be used to remove blockages in all chakras.
