Chalcopyrite, sphalerite-marmatite, quartz and calcite

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.

Japanese law twin in quartz with sphalerite-marmatite, pyrite and galena

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“

Galena, chalcopyrite andsphalerite

A very nice, cabinet size specimen, of large cubic crystals, developed singenetically with black sphalerite- marmatite and overgrowth by chalcopyrite. Galena is slightly dissolved.

 

Galena, pyrite, sphalerite and quartz

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

 

„Melted“ galena, sphalerite – marmatite

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.

Chalcopyrite, sphalerite and galena

An outspending cabinet size specimen of strongly dissolved galena, followed by very well terminated large chalcopyrite crystals with striation, and by sphalerite- marmatite crystals.
