Black Tourmaline is one of the most powerful crystals for protection and elimination of negative energy. Black Tourmaline helps to put an energetic boundary between you and others, so that you don't pick up unwanted energies. Use your Black Tourmaline point in a meditation each morning to create a shield of protection around your body before you leave your home.

Although not typically thought of for this, Black Tourmaline is also one of the most powerful crystals for anxiety. When you feel yourself getting overwhelmed, or if you're having an anxiety attack, hold a Black Tourmaline touchstone in each hand and you will feel its energy sucking the negativity, fear and bad vibes out of your body.
