Natural Black Tourmaline Pendants. Black Tourmaline is one of the best stones to use for protection and to dispel and neutralize negative energies. Also grounding and focusing. The black color goes with anything you wear, it can be casual in a black rope or more dressy with a nice silver chain. We love to wear or have black tourmaline in any occasion and when in need of a little more assertiveness, boundaries, protection and focus.
