   Summary Author:  Allen Steinburg

   Rainbow  pyrite is the trade name for Pyrite Druzy and a non-Quartz
   species of  gemstone. These colorful rock specimens are valued for
   their rainbow-like iridescence caused by differential  refraction
   and diffraction of light. Historically, this metallic looking rock was
   extracted in Russia, however, the former  1870 abandoned Shipman
   pyrite mine in Ontario, Canada is proving to be another source for
   rainbow pyrite along with uncommonly large octahedral pyrite crystals.
