Iridescent Covellite with Pyrite (classic locale)

Item Description

A sharp and jagged "mountain" of iridescent peacock-blue and magenta covellite plates is jauntily perched on the sparkly, brassy, pyrite microcrystal-rich matrix on this showy and excellent old-timer from the famous East Colusa Mine at Butte. A highly representative two-sided example of the species and renowned locale.
