Black Tourmaline is an excellent crystal for everyone because it's the bodyguard stone that provides protection and elimination of negative energy. It promotes a sense of power and self-confidence, allowing for a clearer, more objective view of the world. It is empowering to those who must live or work in challenging environments or when facing difficult circumstances. Black Tourmaline is also one of the most powerful minerals for absorbing electromagnetic radiation, which makes it excellent for placing near computers and other electronics. Also a powerful protector against energy vampires, helping to put boundaries between yourself and others. Black Tourmaline jewellery worn is a reminder that there's a line that can never be crossed, which keeps bad energy from getting into your psyche. You can also carry it in your pocket or place it around your home or work. stone 80g - 2"x1"x1"
