NX8L6: Parallel growth of idiomorphic Baryte crystals, one of them dominant, with excellent transparency and brilliance. Their upper and side faces have very well marked triangular growth figures that give the edges a sawtooth appearance. Also we can see corrosion and contact geometric structures on some faces. We call your attention to the interesting Chalcopyrite crystal inclusions, where the original yellow greenish color is preserved, while superficial crystals on Baryte faces are covered by a thin oxidation layer. The specimen is from mining works of Aizpea, close to the La Troya Mine.
