Splendid morphology for this Chalcopyrite, Sphalerite combo specimen. Black Sphalerites octahedrons grow one atop another and yellow Chalcopyrites intergrow with them making excellent formations of mutual intergrowth, replacement and penetration – really amazing. Sphalerites have some gemmy areas. Small doubly terminated Quartzes and Pyrites are seen too. Beautiful display from many angles. In excellent condition – some small nicks.

Tempting!
