This 100g pack of small black tourmaline tumble stones would be great for use in your crystal grids. Please note the stones are smaller than the tumble stones sold individually, and you’ll receive roughly 30-38 individual pieces to make up the 100g.
Black tourmaline is a protective stone, protecting against cell phones, electromagnetic smog, radiation, psychic attacks and negative energies of all kinds. Connected with the base chakra, it grounds energy and increases physical vitality, dispersing tension and stress.
