A lodestone is a naturally magnetized piece of the mineral magnetite. The lightly magnetic property of this rock specimen is demonstrated by the included clinging iron filings. This stone contains iron ore, the earth’s only natural magnet. Ancient people first discovered the property of magnetism in lodestone. Pieces of lodestone, suspended so they could turn, were the first magnetic compasses, and their importance to early navigation is indicated by the name lodestone. Healers use this mineral for issues with asthma, blood & circulatory system, skin, hair, muscle strains, cramps and nosebleeds. The lodestone measures approximately 2.6 – 3.5 inches. Picture is representative of the specimen you will receive. Each rock is unique and will vary in shape, size and appearance. Storing them with a neodymium magnet will increase the magnetism. Ages 8 and up.
