Chemically and mineralogically, the lodestone is magnetite, a massive type of iron ore, an oxide of iron, a mineral related the the brown stuff coating the magnetic disks and tapes used by computers. Magnetite is quite common in nature, while lodestones are relatively rare. What if no lodestones existed? The Chinese would certainly not have invented the magnetic compass. Magnetism would have been discovered much later, and one wonders how. Lacking the compass, the great voyages of discovery could hardly have taken place--Columbus, De Gama, Magellan and the rest. The history of the world might have been quite different! These rocks come in irregular shapes and sizes approximately 0.5 to 1 inch in diameter. Sold by the piece.
