Attractive specimen of Chalcopyrite crystals contrasting strongly on a base of Sphalerite and Quartz from Madan ore field, Bulgaria. It displays very well isolated golden-yellow Chalcopyrite crystals to 17mm decorating the black Sphalerite-Quartz base. The Chalcopyrite crystals are sharp, tetrahedral, with good luster and complete all over. Beautiful display specimen with excellent focal point – very aesthetic. In superb condition.

Marvelous!
