A beautiful tumbnail specimen of steep scalenohedrons calcite crystals, covered by several generations of calcite aggregates. In the last stage of crystallization process on the top were developed excellent terminated flat calcite rhombohedron transparent to translucent crystals with yellowish color.
Тип минерал: psudomorph
Calcite rose – pseudomorph of calcite after calcite with quartz
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.
Calcite after calcite psudomorph on quartz coated by lemonite
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.
Calcite after calcite pseudomorph coated by lemonite on quartz
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 after calcite on quartz pseudomorph
Calcite steep scalenohedron crystals, developed on the top of quartz and followed by several generation of micrograne calcite
Pseudomorph of calcite after stilbite, after calcite on quartz
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.
Quartz after calcite pseudomorph, particularly coated by limonite
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.
Quartz after quartz and calcite pseudomorph with 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
Calcite after calcite pseudomorph coated by limonite on quartz
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.
Pseudomorph of pyrite after chalcopyrite and galena
An excellent, large cabinet size specimen, presenting galena crystalized on chalcopyrite, and after particular desolvation, corroded by pyrite replacing chalcopyrite and galena
