Very nice specimen showing light dissolution and exceptional step-growing of galena crystals, combined with beautiful chalcopyrite, quartz and sphalerite.
Bad picture of an excellent specimen. – in the internal cavity of ore body are found very well terminated flat galena crystals with cubic faces. They are singeneticaly accompanied by lustrous sphalerite and chalcopyrite. Crystallization happened in the internal part of the cavity and crystals are strangely arranged as architecture ensemble showing center of empty spaces
A very aesthetic and attractive specimen showing almost full paragenesis set – Chalcopyrite, galena, sphalerite, pyrite, and quartz. The specimen is strongly oxidated – galena crystals lose their luster and chalcopyrite is oxidated with different stage and coated in some places by bornite.
An excellent specimen built large, very well terminated and shiny chalcopyrite crystals corroded by galena, pyrite and sphalerite. On some of the chalcopyrite crystals could be seen „elephant skin“ what is usually sign for internal dissolution and recrystallization – in that case, replaced by galena and pyrite.
A nice specimen formed by several large chalcopyrites well-shaped crystals developed on quartz and overgrought by sphalerite and galena. Oxidation gives to chalcopyrite deep dark gold color
A very well shaped galena crystals singeneticaly developed with chalcopyrite and overgrowing large transparent quartz crystals, followed by very thin double terminated quartz crystals of second generation
An excellent „all in one “ specimen, showing almost full paragenesis in the deposit – pink manganocalcite, pyrite, sphalerite, chalcopyrite, and quartz. on the mix of pyrite, sphalerite, chalcopyrite, galena, and quartz grow pink manganocalcite flat crystals
Very interesting specimen showing deep colored green quartz covered ( most likely) by calcite and second stage of mineralization process including quartz, chalcopyrite, galena, and pyrite. In the end of the process calcite was dissolved and between 2 phases of mineralization was formed empty space and effect of second“skin“ of the specimen.
Very nice small intense green quartz crystals singeneticaly developed on mother-rock with galena, pyrite, chalcopyrite and second generation of very thin quartz crystals.
The unique specimen I never see for the last 30 years. It presents oxidated galena crystals and green transparent to translucent sphalerite (cleophane) developed on the surface of large quartz crystal and covers it almost completely. The unique property of that specimen is singeneticaly coating the surface of part of sphalerite crystals at the end of their crystallization and after that, as result, we have excellent golden color and irisation in some parts (reminding tiger eye). Excellent chalcopyrite coating forms planes in the crystals and helps for irisation. The surface coating also appears in some parts and makes specimen even more colorful.
