Pyrite - or "Fool's Gold" like most other metallic gems are stones of masculine energy. Vitality and will power are also increased as it has a tendency to effect your ability to manifest & take on challenges. In ancient times the Incas used pyrite as mirrors.
Pyrite can also be used for creativity, ambition, & commitment which I'm starting to personally learn and work with more. Fantastic and slept on stone!ld) in polished Brass
