Tumbled hematite Iron oxide (Fe2o3). Also known as bloodstone. A close relative of magnetite. The difference is that hematite is non-magnetic (because of its trigonal structure, magnetic domains form but are aligned in anti-parallel fashion, so magnetic fields cancel out). Hematite is said to help strengthen the circulatory system and to help in the treatment of blood disorders. For a rejuvenating and revitalizing effect, you should hold in each hand an hematite stone (circulatory system, strengthens the blood), a copper stone (stimulant) and a double terminated crystal (amplifier) for a maximum of 15 minutes. A black tourmaline is required to be better grounded and connected with the Earth.
