One extraordinary and very rare specimen of flat galena crystal on the base of calcite with signs of dissolution.
Тип минерал: calcite
Pseudomorph of calcite after calcite with dolomite coated by limonite
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.
Chalcedony pseudomorph after calcite – cast
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.
Calcite and manganocalcite
One very rare specimen, combination of two steep scalenohedron manganocalcite, overgrowth by transparent calcite – forming phantom inside transparent calcite
Galena, sphalerite – marmatite, quartz and calcite
An amazing, large cabinet size specimen of mirror shiny galena with very lustrous black marmatite and transparent quartz crystals, covered by white calcite
linarite, azurite, chrisocola, cuprite, calcite and quartz
An excellent specimen of blue linarite and chrysocola, developed in limestone mother rock, with azurite, cuprite and quartz.
Calcite after calcite and dolomite pseudomorph
An excellent cabinet size specimen of calcite crystals, covered by dolomite. After dissolution, start new crystallization of calcite aggregate, followed by rhombohedral calcite crystals.
Manganocalcite with quartz, pyrite and sphalerite
One extraordinary specimen of single manganocalcite pink crystal, singenetically developed with small transparent rock crystal,green prazem quartz crystals, pyrite and sphalerite.
Quartz with calcite „hat“
An excellent thumbnail of transparent clear quartz covered by calcite aggregate of small calcite crystals and in the end of crystallization process with one rhombohedron crystal developed on pyramidal face of the larger quartz crystal.
Pseudomorph of quartz and calcite after stilbite on quartz
One old large cabinet size specimen showing in very aesthetic way pseudomorph of alternating calcite and quartz layers on the top of stilbite crystals developed on short axes quartz crystals.
