One very nice miniature specimen of steep scalenohedral calcite crystal, developed on quartz and coated by limonite.
A beautiful specimen of Calcite, quartz
Size: 65 x40 x 38mm
Weight: 109 grams
A specimen that you receive may look slightly different in color from the one on the photographs. Because of the lights used to make the photos.

One excellent specimen of thin quartz crystals covered by calcite. In the latest stages of crystalization, a large rhombohedron calcite crystal crystalize on top of quartz
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.
One amazing small specimen of mixed quartz-calcite aggregate followed by galena and covered by not identified (yet) secondary copper mineral- most likely hemimorphite or chrisocola.
A rare and very beautiful specimen of galena and pyrite followed by clear long quartz crystals, covered by green quartz colored by chlorite and overgrowth by thin grain calcite. On the top of the specimen is developed large translucent calcite crystal with clearly twined down part of the crystal
One excellent small specimen of oxidized galena, covered by calcite followed by chrysocolla and other secondary copper minerals.
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.
One very rare cabinet size specimen, presenting chalcopyrite, galena, sphalerite, quartz, and calcite. The chalcopyrite crystals are very unusually elongated in the direction of „C“ ax, instead of the usual tetrahedral crystals.
One excellent and very aesthetic, cabinet size specimen of thin flat crystals of calcite-manganocalcite ( paperspat) developed on rainbow pyrite, quartz and lustrous crystals of sphalerite- marmatite and quartz.
