“Excellent idiomorphic Barite crystal, with excellent transparency and brilliance. Its 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 on the interesting Chalcopyrite crystal inclusions, where the original yellow greenish color is preserved, while superficial crystals on Barite faces are covered by a thin oxidation layer. The specimen is from mining works of Aizpea, close to the La Troya Mine.Aizpea Mines, Zerain, Guipuzkoa, Spain.Found in 03/2001Specimen size: 4.7 × 4 × 1.8 cm ”
