Description

Primarily this is NOT a Ferberite specimen it is a Chalcopyrite piece. Here we have several golden, excellent developed but slightly deformed crystals of Chalcopyrite accompanied by black multifaceted Sphalerite and less, but still there, bladed Ferberite. The Chalcopyrite itself is many-faced, sharp edged and has a fine metallic sheen. A super and mostly pristine specimen from the heydays of this great mine, probably the 1970s.
