For general house protection from negative energies, we highly recommend Black Tourmaline. It is among one of the most protective and grounding crystals. It protects against all forms of negative energies, including electromagnetic smog (EMF), and geopathic stress. You can place these crystals either on the corners of your property or inside of your house to create a pyramid of protection. Please note that crystals can vary in shape, size, colour and consistency.
