This super cool magnetic stone is sold in pairs. When gently tossed together the stones emit a vibrational sound and so are affectionately called Singing Stones. A "stone for the mind", Hematite stimulates concentration and focus, enhances memory and inspires original thought. Hematite utilizes the magnetic qualities of the yin-yang energies to balance meridians within the body and provide a stable equilibrium between the ethereal nervous system and the physical nervous system.
