Splendid rare specimen of iridescent chalcopyrite completely covering elongated chalcocite and djurleite from Tongshankou Mine, China. The specimen has a beautiful dendritic crystal growth with delicate arborescent shape. Chalcopyrite has glittering purple, blue and green variations which gives a colorful display. The colors are with electric nuances. Complete all over 360 degree. For references see the 2014 issue of The Mineralogical Record vol. 45, # 1. In very good condition – some small damages. On acrylic base.

Fascinating!
