One very nice cabinet size specimen, presenting group of large galena crystals with signs of dissolution on the top of chalcopyrite corroded and replaced by pyrite, followed by quartz.
One beautiful specimen of very aesthetic, perfectly shaped thin quartz crystals with very lustrous crystal faces with well developed pyrite crystals,slightly oxidized to red color.
A beautiful and very aesthetic cabinet size specimen of chalcopyrite crystals on the top of galena and sphalerite, followed by quartz. Chalcopyrite crystals are internally corroded by pyrite.
An excellent well space developed specimen of sphalerite chalcopyrite and pyrite followed by quartz.
One small beautiful specimen of sphalerite and galena mother rock overgrowth by quartz pyrite and galena
One large cabinet size cluster of well developed mosaic quartz crystals developed together with pyrite crystals which start their development inn the last stages of growing of quartz. As result part of the pyrite crystals are inside quartz and the rest is on the top of the crystals.
One beautiful and rare cabinet size specimen, presenting almost full paragenesis set of Madan deposit. Galena is with large cubic skeletal crystals and mosaic developed crystal faces, overgrowth by large green quartz crystals and chalcopyrite, which is secondary oxidated and replaced by pyrite well shaped shiny crystals.
One very interesting specimen of chalcopyrite and pyrite on mother rock, followed by galena. Chalcopyrite is internally corroded and replaced by small pyrite crystals. Galena crystals are particularly corroded and coated by bornite.
A beautiful cabinet size specimen presenting very well terminated galena crystals with sphalerite and pyrite, covered by thin long-axes transparent quartz crystals
One extraordinary specimen of galena on the top of black sphalerite- marmatite and chalcopyrite, followed by pyrite. Galena crystals are with rounded edges, due to strong dissolution
