Pyrite or Fool's Gold

Pyrite, widely known as Fool's Gold, is a natural iron sulfide mineral, FeS2, with a brass-yellow colour and a bright metallic shine. 

Named from the Greek word for fire because it sparks when struck. It is often confused with real gold despite being harder and much lighter.

It promotes strength of mind, body, will and character. It is strong like iron. Pyrite reflects the energy of Gold, bringing success, enthusiasm, happiness, and power. It is traditionally the color of kings, riches, and the sun.
