Black tourmaline tumble stones are prized by crystal enthusiasts for their grounding properties and protective energy. These smooth, polished specimens showcase the deep black luster characteristic of raw tourmaline, making them ideal for meditation, energy work, or collection display. Each tumble stone is naturally formed and varies slightly in size and appearance. Perfect for carrying in a pocket, placing on an altar, or incorporating into crystal grids. Black tourmaline is traditionally valued for its ability to anchor scattered energy and promote stability during times of transition.
