Black tourmaline's legend was to be a strong amulet, bouncing the negative energy and shielding your surrounding. Due to its unusually high amount of iron, this stone naturally protects you from electromagnetic stress and is said to harmonize the brain. It has also been studied and used to help activate the immune system. This stone, when placed on a wound, is said to help heal scars faster. Use black tourmaline to dispel any self-judgment, worry, anger, or any other toxic emotion.
Tourmaline is the modern birthstone for the month of October and is used to celebrate the 40th anniversary of weddings.
