About Black Tourmaline Crystal Tumbles
Black Tourmaline, also known as Schorl, in its raw state is very easy to distinguish as it has rough creases and grooves. As a tumbled crystal however, it almost looks like all the other black crystals except for one difference, it will still have grooves visible as it doesn’t polish up perfectly smooth.
Black Tourmaline crystal protects against negative energies and disperses stress and tension. It is a powerful, protective crystal and is great at removing your own negative thoughts, self-judgement and anger. It can also be used for grounding.
Black Tourmaline is excellent to place near computers and telephones to dissolve electromagnetic energy.
