Black Tourmaline has become one of my closest companions in the stone world. I wear it as much as I wear Turquoise (I wear Turquoise a lot), often together.  It is the alchemist in the geologic kingdom. Yes, it is grounding. Yes, it is protective. It also, magically, is believed to absorb negative energy and transform it into something lighter, easier. Energy is energy... Black Tourmaline helps to ensure that the energy around you is only the good stuff.  When it's not? It makes it the good stuff.
