The mineral pyrite, or iron pyrite, is an iron sulfide. This mineral’s metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well known nickname of “fools gold.” The name pyrite is derived from the greek “pyrites” “of fire” or “in fire.” In ancient Roman times, this name was applied to several types of stone that would create sparks when struck against. Found in many places around the world with large deposits in Italy, France, Spain (famous for its single cubes of Pyrite), Peru, Bolivia, Mexico, Romania, Sweden, Norway, Germany, Japan, and the North American States of Arizona, Utah, Colorado, Illinois, and Pennsylvania. Pyrite is a stone of intellect and protection.
