A super Tetrahedrite crystal specimen from the Casapalca Mine, Peru. The specimen is aesthetically dominated by a classic tetrahedral crystal of Tetrahedrite measuring to 2.5cm on edge, brightly metallic grey-black. Suitably associated with contrasting prismatic gemmy colourless to white translucent Quartz crystals, with several more well formed Tetrahedrite crystals and a scattering of light metallic yellow pyrite crystals. A fine small cabinet specimen for display.
