One very attractive large cabinet size specimen of quartz, overgrowth by large chalcopyrite crystals in combination with sphalerite-marmatite and galena. In some parts, chalcopyrite is corroded by small pyrite crystals, which is common in this mine. In the last stages of crystallization dolomite, coated with limonite formed small round crystals of all previously crystallized minerals.
