Attractive specimen of Chalcopyrite decorated by Sphalerite and Quartz. Yellow Chalcopyrite forms the base. It has rich golden-yellow color and some iridescence. Black Sphalerite grows atop in a cluster. The crystals are sharp and lustrous truncated tetrahedrons. Minor Quartz crystals are seen too. In good condition – some nicks and back side damage.

Unusual and aesthetic!
