Killer 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 Quartzes, sparkling Pyrites and Galena cubes are seen too. Beautiful display from all sides -360 degree specimen. In superb condition.

Marvelous!
