An excellent specimen built large, very well terminated and shiny chalcopyrite crystals corroded by galena, pyrite and sphalerite. On some of the chalcopyrite crystals could be seen „elephant skin“ what is usually sign for internal dissolution and recrystallization – in that case, replaced by galena and pyrite.
Short axes quartz crystals followed by well shaped steep scalenohedral calcite and quartz after calcite pseudomorph (alternation of calcite and quartz layers), coated by limonite-hematite.
Very nice and aesthetic small specimen showing scalenohedral calcite crystals developed on top of quartz and overgrought by second-generation rhombohedral calcite crystals, covered by white quartz.The second generation is orientated perpendicular to first generation calcite and along the edge of the crystals.
small specimenshowing clear pseudomorph. On quartz crystals are developed well shaped double terminated scalenohedron calcite crystals, covered by quartz. As a result ot late dissolvation part of calcite is dissolved.
25 years old specimen presenting very detailed pseudomorph of chalcedony after well shaped calcite crystals. Clearly could be seen all details of calcite sharp scalenohedron crystals and small ball like dolomite crystals. All of the calcites were dissolved and now crystal shapes are hallow.
Well terminated qartz crustals, overgrought by doubleterminated calcite scalenohedron situated in perpendicular direction of „C“ axes of quartz, covered by second generation of short prismatic very well shaped shiny quartz crystals, covered on the back side by golden color syderite.
Unique specimen showing a large single chalcopyrite single crystal, internaly dissolved and replaced by pyrite. As result of that groing pyrite crystals pree from inside and brake mother crystals. In the latest stage of crystalisation, small crystals of chalcopyrite cover all previous mineralisation inside and outside the crystal. and in the last was slightly oxidated and coated by bornite and covelite
Small calcite rombohedron crystals, covering massive calcite aggregate covering calcite replacing stylbite crystals.
Perfectly shaped steep scalenohedron calcite crystals, presenting calcite after calcite pseudomorph.
Aesthetic complicated mineralogical specimen, presenting a pseudomorph of quartz after calcite after stylbite- large stylbite crystals were replaced by calcite aggregates, covered and particulary replaced by transparent quartz crystals
