Amazing and very rare matrix specimen of iridescent Chalcopyrite completely covering elongated Chalcocite and Djurleite from Tongshankou Mine, China. The specimen has beautiful dendritic crystal growth with delicate shape. The Chalcopyrite has glittering purple, blue and green variations which gives a colorful display. Some Quartz crystals are seen too. For references see the 2014 issue of The Mineralogical Record vol. 45, # 1. In very good condition – some minor damages.

Delectable rarity!
