Lodestone, also called magnetite, is a black magnetic stone made from iron oxide and is very amplifying. You can find it with small pieces of iron stuck to it from magnetism. If you do find it this way, be sure to store it away from other crystals so you can retain the small pieces of iron with it. Lodestone helps with grounding, protection, and attracting what you create. You can place it near the root chakra, in a bracelet. It is a very strong stone and should probably be stored in a protective container even when being used. It is associated with the root chakra. It can be found naturally, natural with iron stuck to it, or tumbled and polished.
