Green sphalerite – cleophane with exceptional transparency on the top of galena
One exceptional, large cabinet size specimen, with green sphalerite and very high transparency, developed on the top of galena crystals and chalcopyrite. Specimen has a cut base.
Tra on quartznsparent green sphalerite-cleophane
Small but very nice specimen of transparent isometric sphalerite-cleophane crystals with intensive green color on the top of quartz aggregate. The biggest crystal is broken and secondary rehealed on the place.
Cluster of galena mosaic galena cristals with chalcopyrite
A very nice cabinet size specimen of step developed cubic galena crystals with signs of dissolvation in the last stages of mineralisation process. There also a part of broken chalcopyrite crystal on the top of galena
Red garnet almandin with quartz
One beautiful cabinet size specimen of very well terminated, red color garnet crystals with size up to 5-8 mm, with very lustrous faces. What is very rare to see is part of the cavity pegmatite mother rock where are developed almandin crystals.
Lemonite quartz
A cabinet size very aesthetic group of long axes quartz crystals, coated by lemonite and covered in some parts with small calcite aggregates.
Cluster of mosaic, skeletal developed galena crystals
An excellent cabinet size specimen, showing cluster of large galena cubic crystals, with mosaic skeletal development and signs of light dissolvation.
Calcite rhombohedron crystals on quartz
A very aesthetic large cabinet size specimen, presenting group of flat rhombohedron yellow calcite crystals developed on quartz.
Quartz after stilbite on quartz pseudomorph
One large cabinet size attractive specimen showing comparatively rare situation of large stilbite crystals developed on quartz and lately exchanged by calcite and covered by small grain quartz crystals.
Mirror shiny galena with quartz
An excellent cabinet size specimen of galena, with very lustrous and shiny faces. Crystals are developed in the cubic shape. Galena crystalize on the back side of tectonically broken quartz and reconstructed older galena generation.In the last stage of development there are signs of „desolvation waves“
