Black Tourmaline (also known as Schorl) is widely used in crystal healing and metaphysical practices as a primary stone for protection, grounding, and energy purification. Core Metaphysical Properties • Energetic Protection and Shielding: It acts as a barrier to block and absorb negative energies, lower vibrations, psychic attacks, and unwanted influences from people or environments. • Grounding and Stability: It connects directly to the root chakra, anchoring your energy to the Earth to promote physical security, safety, and emotional balance. • EMF Deflection: It is commonly used to absorb or shield against electromagnetic fields (EMFs) emitted by electronics like cell phones, Wi-Fi routers, and computers. • Anxiety and Stress Relief: It helps calm racing thoughts, clears fear, worry, and anger, and encourages rational thinking and resilience. • Auric Cleansing: It purifies the energy field (aura) and transmutes dense, negative vibrations into lighter, positive ones.
