An excellent cabinet size specimen of steep scalenohedron calcite crystals followed by flat transparent to translucent rhombohedron crystals
A very aesthetic large cabinet size specimen of transparent green sphalerite- cleophane and calcite overgrowth by white thin long axes crystals
A beautiful cabinet specimen of sphalerite and chalcopyrite followed by pyrite, which corroded chalcopyrite by internal replacement, in some places breaking from inside mother chalcopyrite crystals. #1373
One excellent, large cabinet size specimen of perfectly developed in space net transparent quartz crystals overgrowth by large black lustrous sphalerite- marmatite crystal and small also very lustrous cubs of pyrite
One very aesthetic cabinet size specimen of perfectly developed amethyst crystal overgrowth on colorless small quartz crystals.
One excellent miniature of brown-green barite crystals on white quartz. Barite is with phantom in some places.
Fragment of sphalerite- cleophane crystal with size 16 x 12,5 x 6 mm – weight 2,2 grams. The specimen is completely transparent, color is light green to yellow green and colorless in the center the color is spread in color zones. Internal space is clear of inclusions. Pictures are taken in reflected halogen light on white background.
One beautiful cabinet size crystal specimen of quartz – rock crystal. The specimen is built in the long axis transparent crystals with lustrous faces and interesting – one side development of the top fo quartz crystals. One of the sides of the pyramid faces is much stronger developed than the others, which most likely is caused by a strong solution flowing during the crystallization process.
One exceptional specimen , build in small quartz crystals, covered by black sphalerite and overgrowth by calcite aggregate. On the top is situated large, translucent double terminated calcite scalenohedron crystal. What is very rare, is that one of the ends of scalenohedron is twined in a „swallow-tail“ twin.
An excellent cabinet size specimen of galena, overgrowth by sphalerite and pyrite, followed by quartz and calcite.
Pyrite is strongly oxidized and the color is changed to yellow-red with variations.
