Pyrite is the classic "Fool''s Gold". There are other shiny brassy yellow minerals, but pyrite is by far the most common and the most often mistaken for gold. Whether it is the golden look or something else, pyrite is a favorite among rock collectors. It can have a beautiful luster and interesting crystals.
A type of metal sulfide ore deposit that contains varying amounts of pyrite, copper, gold, silver lead and zinc sulfide mineral in layers. They form when hot fluids circulate through rocks of the seafloor, dissolving various metals, and then come into contact with cold seawater, causing the metals to precipitate as piles of tiny mineral grains.
