Black Tourmaline Chunk

** Uses of Black Tourmaline** Traditionally valued for its grounding and protective energy, black tourmaline is believed to anchor you to the present moment and create a sense of stability and security in your spiritual practice. **Product Description** These natural medium chunks of black tourmaline showcase impressive hardness and a natural shine on one side that reveals their authentic formation. Sourced from Brazil's premier mineral deposits, each piece is composed of elbaite tourmaline—an aluminum borosilicate mineral containing aluminum, boron, silicon, and oxygen. The deep black coloration comes from trace elements within the crystal structure, making these specimens ideal for collectors and those seeking grounding stones for their spaces.
