A very nice specimen of very well shaped chalcopyrite crystals, with striated crystal faces and covered by lustrous black sphalerite with thetrahedron vicinality signs on the surface. In the end of the crystallization process were formed quartz and calcite crystals.
A beautiful cabinet size specimen of transparent quartz crystals colored by chlorite and overgrowth by steep skalenohedron crystals of calcite-manganocalcite
An excellent and very rare specimen presenting calcite scalenohedron crystal, developed on quartz , followed by stilbite, lately replaced by calcite
An excellent cabinet size specimen of transparent quartz crystals, followed by calcite, sphalerite and galena. Galena crystals have a traces of skeletal development and are dissolved forming so we call „melting“ effect
One extraordinary and very rare specimen of flat galena crystal on the base of calcite with signs of dissolution.
Morphology miracle. One very rare specimen of pseudomorph of calcite after calcite with dolomite coated by limonite. Morphology is very rare because of parallel growing of steep scalenohedron calcite crystal and two isometric rhombohedron calcite crystals.
An exceptional specimen of very thin „skin“ of chalcedony developed on large calcite scalenohedron crystals, lately dissolved. Chalcedony aggregates copy all small details of former calcite crystals, including crystal faces sculptures.
One very rare specimen, combination of two steep scalenohedron manganocalcite, overgrowth by transparent calcite – forming phantom inside transparent calcite
An amazing, large cabinet size specimen of mirror shiny galena with very lustrous black marmatite and transparent quartz crystals, covered by white calcite
An excellent specimen of blue linarite and chrysocola, developed in limestone mother rock, with azurite, cuprite and quartz.
