Delicate and very subtle, but at the same time very durable choker with faceted black tourmaline and gold-plated silver beads. Black tourmaline is considered the strongest protective stone. It protects against energy outflow, against energy vampires, raises vibrations, and provides a protective shield against negative energy. Other fasteners to choose from in the options. The photo shows hand-forged brass. The whole thing is mounted on a surgical steel cable. The product does not cause allergies.
