Rare specimen of iridescent Chalcopyrite completely covering elongated Chalcocite and Djurleite. The specimen has a beautiful crystal growth with delicate arborescent shape and twinning. Chalcopyrite has glittering purple, blue and green variations that give a colorful display. The colors are with very electric nuances. Displays from all sides. For references see the 2014 issue of The Mineralogical Record vol. 45, # 1. In very good condition - some small contacts. On acrylic base.
Splendid!
