Pseudomorph of quartz after calcite

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.

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

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 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.
