About Chalcopyrite
A copper iron sulfide, with a brassy yellow color, often tarnishing to iridescent hues. It's known as a stone of abundance, perception, and clearing energy blockages, enhancing intuition. (Can be mistaken for Pyrite/Fool's Gold).
Primary Hues
Brass-Yellow, Golden-Yellow, often tarnishes to iridescent purple, blue, green
