Pyrite Suns are found in the coal mines of Sparta,Illinois at the 300 foot level in a very narrow seam lying on top of the coal vein. Miners in four mines bring them out in their lunch buckets, thus preserving what would otherwise be destroyed in the mines. Originally thought to be marcasite, research by the Smithsonian Institute has proven them to be pyrite, and therefore, very durable. Surrounded by black shale and coal, a very difficult cleaning process unveils their
hidden beauty. Dating in age to 350 million years old, one of the present theories of origin has them as a pyritized fossil replacement.
