Tennantite is a copper-iron-arsenic sulphide mineral commonly found in hydrothermal veins and metamorphic deposits, often associated with other copper minerals. It typically forms metallic grey to dark silver crystals with a submetallic to metallic lustre, sometimes exhibiting a reddish or iridescent tarnish. In folklore, Tennantite symbolises resilience and abundance. Metaphysically, it is believed to enhance focus, determination, and grounding, supporting personal growth and clarity. The stone is said to absorb negative energy, encourage confidence, and strengthen one’s connection to both the Earth and spiritual energies.
