One exceptional and very aesthetic cabinet size specimen of small cubic and very lustrous galena and pyrite crystals, covered by very thin clear small quartz crystals, very interesting arranged in the space, forming the starts like groups of crystals.
One excellent miniature specimen of clear quartz crystals overgrowth by several twined and very well terminated chalcopyrite crystals, followed by black and very lustrous sphalerite – marmatite tetrahedral crystals, covered by round yellow-orange dolomite
One wonderful cabinet size specimen of chalcopyrite overgrowth by large cubic galena crystals.
An excellent, large cabinet size specimen of quartz overgrowth by sphalerite, galena and followed by very well shaped chalcopyrite. Galena is strongly dissolved in the latest stages of the mineralization process.
One extremely rare specimen showing both varieties of sphalerite – cellophane (cleiophane) and marmatite. The large green transparent to translucent sphalerite – cleophane isometric crystal, was developed on quartz and galena and lately was overgrowth by small black opaque tetrahedral crystals of marmatite, which shows the evolution in feeding hydrothermal solutions.
One very rare and very aesthetic specimen of space developed, double-terminated clear quartz crystals, overgrowth by galena, lately strongly dissolved galena crystals, to reaching amorphous shape. At the end of the crystallization process, small round dolomite crystals were formed on the quartz crystal faces.
One amazing specimen of a very well terminated cluster of black and very lustrous sphalerite-marmatite crystals, overgrowth by galena crystals, lately strongly dissolved to nearly amorphous shape.
One amazing and very aesthetic cabinet size specimen of large pyrite cubs overgrowth by tetrahedral small sphalerite-marmatite crystals, followed by galena crystals, lately strongly dissolved to an amorph shape. Pyrite crystals were also under oxidation and are coated by bornite-covellite, which shows a beautiful rainbow effect.
