Black Tourmaline Tumbled Stone - 15-30 mm

Black Tourmaline tumbled stones in this grade are smooth, rounded pieces in dense, even black, often showing fine lengthwise striations, polished to a bright finish and sold individually or by weight. The surface character and lustre vary from stone to stone, and the stones feel solid and weighty. The strong dark look suits pocket carry, display, and protective grounding layouts.

Black Tourmaline is traditionally associated with protection, grounding, and a calm, settled sense of safety, and is one of the most popular stones for clearing and shielding. It is commonly carried or placed in a space as a protective presence, kept near a doorway or desk, or added to grids focused on grounding and calm. As a tumbled stone, Black Tourmaline is easy to hold, pocket, or set out where a strong grounding anchor is wanted.

Because this is a natural material, surface character, lustre, size, and weight vary from stone to stone, so the piece you receive will differ from the photographs.

Geological Information
Black Tourmaline, known mineralogically as schorl, is an iron sodium borosilicate of the tourmaline group with a Mohs hardness of 7 to 7.5, taking its black colour from high iron content. Schorl is the most abundant tourmaline variety and is found globally in granites and metamorphic rocks, and it is a natural, untreated material. Sources include Brazil, the United States, several African countries, Pakistan, and Afghanistan.
