Black Tourmaline crystal is a powerful stone for protection against negative energy of all kinds including psychic protection and EMF protection. It is also a strong spiritual grounding stone.
Also known as Schorl, it encourages optimistic attitudes as well as good luck and happiness, regardless of the circumstances that you find yourself in.
Many people, and I am among this group, believe this is the best protection stone that you can use. Its wonderful to hold Black Tourmaline in your hand as it has such a positive energy!
It is one of the most popular crystals to be used for metaphysical purposes. They are wonderful healing crystals for you to use as they bring relief from pain, boost the immune system, aid stress and arthritis.
