Tourmaline is the protective stone par excellance.
It protects against radiation from mobile phones, electromagnetic mist, radiation, psychic attacks, curses, evil intentions and all sorts of negative energy in general. We should place it between ourselves and the emitting source of electromagnetic radiation.
Tourmaline is really beneficial for plants and gardens. It acts as a natural pesticide, keeping plagues away. Buried in the earth it stimulates the growth of plants and is beneficial for the health of crops.
