One perfect cabinet size specimen, illustrating pseudomorph of quartz after calcite developed on quartz crystals. Pulsation of the mineralization process was fixed by developing several stages of mineralization of quartz on the top of steep calcite scalenohedron crystals.
Тип минерал: psudomorph
Quartz after calcite pseudomorph
An outstanding and very aesthetic cabinet size specimens presenting thin quartz „skin“ on the top of the steep calcite scalenohedron specimens. In the latest stages of crystallization, a bigger part of calcite crystals were dissolved and in some parts of the specimen could be seen the hallow cast forms creeping the calcite shape, but consisting only quartz.
Quartz pseudomorph after calcite
One exceptional, large cabinet size specimen of quartz, covering small calcite aggregates and groups of well developed calcite scalenohedron crystals
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 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
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.
