Amazing and rare specimen of iridescent Chalcopyrite completely covering needle Chalcocite and Djurleite from Tongshankou Mine, China. The specimen has beautiful crystal growth of delicate needles over platy base. The Chalcopyrite has glittering purple, blue, green and yellow variations which gives a colorful display. It displays attractively all over 360 degree. For references see the 2014 issue of The Mineralogical Record vol. 45, # 1. In very good condition – some small contacts. On acrylic base.

Delectable rarity!
