Marvelous and unusual Sphalerite with skeletal structure and Chalcopyrite incrustations above. Black Sphalerite crystals with superb luster and complex, stepped faces that form attractive structure. It has excellent parallel striations. On the surface are grown yellow Chalcopyrites. They enrich nicely the display. Some very small Pyrites are grown on the Chalcopyrite. The final accent is one white Calcite at the top. The specimen is complete all over – very small contact areas. In very good condition – small attachments and nicks.

Beautiful and neat!
