Beautiful and rare rainbow of iridescent Chalcopyrite completely covering Chalcocite and Djurleite.  The Chalcopyrite has glittering purple, blue, green and yellow variations that give very colorful display and contrast. The colors are fresh and strong with very electric nuances.  It is complete all over floater and displays from all sides. For references see the 2014 issue of The Mineralogical Record vol. 45, # 1. In excellent condition – some small nicks.
Splendid!
