 | "These beautiful, lustrous pyrite floater "suns" formed between an ancient bed of shale and clay near Sparta, Illinois, over 350 million years ago. This one is complete all-around and front and back. Mineral experts originally theorized that Pyrite Suns were fossilized sand dollars or even ancient lily pads that had been replaced by pyrite. More recently though, mineralogists have speculated that they're actually pyrite concretions which, because they formed between layers of slate, simply had no room to grow into the cubical formations one would normally expect to find.
