This is one of the biggest, well-formed crystals of Chalcopyrite we've ever seen for sale from any locality, although this famous Mexican location produced some that were even bigger and heavier. It is a LARGE, very bright, very beautiful, complex crystal with sensational brassy yellow-green color and metallic luster. It has well-defined crystal faces and edges and looks to be composed of several, smaller, intergrown, tetrahedral crystals. It is the perfect size for a "big specimen" of the species, without the weight of a large plate, and with the impact of the solid crystals front and center for the mass. The main crystal measures nearly 3 inches on edge and it, along with the other smaller crystals, all display fine-scale stepped growth, triangular patterns on their surface for great geometric aesthetics! The brilliant metallic luster, angular crystals and crystal arrangement make for a well composed piece. The Bolivar Mine is a copper-zinc-silver-gold mine and has produced some fine Chalcopyrite specimens and this piece is one of the best we've seen and it sits nicely on its own for display. Ex.
