Chalcedony pseudomorph after calcite

One very rare cabinet size specimen of very thin and strong cast of chalcedony with very light green color, build as a thin skin on the top of the steep scalenohedron calcite crystals, lately completely dissolved. The chalcedony skin followed all sculptures of the calcite crystal faces even in the smallest details. The chalcedony aggregate is very stable and strong, despite their low thickness.

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.

Chalcedony pseudomorph after calcite

Extremely rare specimen of chalcedony thin coat on the top of steep scalenohedron calcite crystals. Chalcedony perfectly copied all details of the surface of calcite crystals . In the fallowed development of solutions, calcite was completely dissolved, and formed pseudomorph cast of calcite.
