Description

Black tourmaline is supplied as a mineral specimen for industrial decorative and specialty applications.

Black Tourmaline, or schorl, is a powerful iron-rich silicate mineral renowned for its deep black color, high-energy protective properties, and grounding capabilities. It is widely used for EMF protection, as it can absorb radiation, and is recognized for its piezoelectric and pyroelectric properties. It is a durable stone (7–7.5 MOHS) used in jewelry and for clearing negative energy. 
Key Aspects of Black Tourmaline:
Protection & Grounding: Considered a premier stone for protection, it is used to repel negative energy and shield against environmental pollutants or stress.
Physical Properties: It often appears with parallel striations on its surface, which is a key identifying feature. It is piezoelectric, meaning it generates an electric charge under pressure or when heated.
Origins & Types: While found globally, significant deposits exist in Brazil, Africa, and Afghanistan. It is a member of the tourmaline family and commonly forms in trigonal crystal systems.
Uses: Used for meditation, Reiki, and as protective jewelry (e.g., bracelets).
Care: While durable, it should not be left in water for long periods, particularly saltwater. 

Metaphysical Properties:

Chakra: Strongly associated with the Root (Base) Chakra.
Zodiac: Associated with Capricorn.
Intentions: Known to reduce anxiety, promote self-confidence, and enhance communication.
