Pyrite Suns

Naturally formed pyrite “suns”.  These flat disc-shaped pyrites have crystals that radiate out from the center like the rays of a sun.  These specimens are from the Spartan Mine in Sparta, Illinois.  More specifically, they are from the Herrin #6 Seam, 280' Level and are dated at  290-320 M Yr Old.  They are found pressed between thin layers of shale.
