An excellent cabinet size specimen, presenting flat calcite crystals ( paperspat) filling a cavity in the mother rock, fallowed by second generation of small yellow-brownish calcite crystals, covering quartz crystals.
One very aesthetic cabinet size specimen of quartz crystals overgrought by calcite and lately covered with several generation of calcite aggregates, In the end all minerals were coated by lemonite.
An excellent cabinet size specimen of steep calcite scalenohedrons, developed on quartz. Calcite crystals are covered by several generation of calcite aggregates and secondary coated by lemonite. In the end of crystallization process on the top of scalenohedrons were developed clear rhombohedrons with flat habit.
Calcite steep scalenohedron crystals, developed on the top of quartz and followed by several generation of micrograne calcite
An exceptional aesthetic and very large specimen presenting a rare pseudomorph of calcite covering spherolite developed stilbite, growing on the top of quartz and on large steep calcite scalenohedral crystals.
One aesthetic specimen showing quartz aggregate covering steep calcite crystal fallowed by second generation calcite. In the end of mineralization process all minerals were coated by limonite, but permanently color stay just on calcite.
A very showing piece of long-axes quartz crystal overgrought by isometric calcite rhombohedron crystal and lately covered by small grains quartz and followed by flat lustrous yellow calcite rhombohedron crystals
One very old cabinet size specimen of quartz, covered with steep scalenohedron calcite crystals, build in the alternation of several generations of calcite and quartz very thin ( less than a millimeter) layers. Later on, these scalenohedron crystals were coated by limonite. At the end of crystallization process appear white, flat rhombohedron calcite crystals.
An excellent, large cabinet size specimen, presenting galena crystalized on chalcopyrite, and after particular desolvation, corroded by pyrite replacing chalcopyrite and galena
A very attractive specimen of steep calcite scalenohedrons followed by thin quartz layers and covered with several portions of later generation of calcite. The crystals were broken by tectonic moves and later rehealed by transparent calcite.
