Plate galena with calcite

One extraordinary and very rare specimen of flat galena crystal on the base of calcite with signs of dissolution.

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

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.

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.
