A nice tumbnail specimen of transparent quartz – rock crystal with isolzted crystals of skeletal developed galena, sphalerite an pyrite
Small but beautiful specimen with aesthetic contrast between cluster of slightly oxidized chalcopyrite and lustrous black tetrahedral sphalerite – marmatite.
A very nice specimen of very well shaped chalcopyrite crystals, with striated crystal faces and covered by lustrous black sphalerite with thetrahedron vicinality signs on the surface. In the end of the crystallization process were formed quartz and calcite crystals.
Absolutely gorgeous and very rare aesthetic specimen, presenting very lustrous galena crystals – strongly dissolved, to rounded shape, followed by black sphalerite – marmatite, with strong black lustrous crystal faces and pyrite. The unique rarest part of the specimen is small Japanese law twin in quartz, which is actually double twined – one and same quartz wind of the twin, has two different „winds“
A very nice, cabinet size specimen, of large cubic crystals, developed singenetically with black sphalerite- marmatite and overgrowth by chalcopyrite. Galena is slightly dissolved.
One beautiful cabinet size specimen of quartz on mother rock and prazem overgrowth by pyrite and black sphalerite- marmatite and well shaped cubic galena crystals
An incredible and very aesthetic cabinet size specimen of well shaped thetrahedrical marmatite crystals, followed by large galena crystals, lately strongly dissolved. Galena is rounded and with very lustrous faces.
One very nice, cabinet size specimen, of strongly dissolved galena overgrowth by sphalerite – marmatite, pyriteand quartz
An outspending cabinet size specimen of strongly dissolved galena, followed by very well terminated large chalcopyrite crystals with striation, and by sphalerite- marmatite crystals.
One gorgeous, cabinet size specimen, with skelatal developed galena with slightly dissolved crystal faces, on the base of quartz, covered by sphalerite and chalcopyrite. In the end of crystallization process chalcopyrite is internally dissolved and replaced by pyrite. Final result is one very aesthetic specimen, with balanced presentation of all minerals.
