Pyrite Suns with fossil fern in matrix. Found 300 feet deep in coal mines in a narrow seam of shale lying on top of the coal vein. Research by the Smithsonian has proven them to be pyrite and iron sulfide, aged 350 million years old, and a theory of origin is they are a fossil replacement. *comes with stand
