A nice tumbnail specimen of transparent quartz – rock crystal with isolzted crystals of skeletal developed galena, sphalerite an pyrite
One exceptional cabinet size specimen presenting excellent and very aesthetic specimen of well shaped isometric sphalerite – cleophane transparent green crystals followed by small cubic galena crystals and short quartz crystals.
One excellent fragment of transparent yellow green to green sphalerite-cleophane, crystal, convenient for faceting. pictures are taken in transmitted (back) cold LED light.
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.
A very nice and well arranged small specimen presenting skeletal developed galena crystals covered by quartz, and followed by two very well terminated chalcopyrite crystals, with very aesthetic and well arranged striation on the crystal faces, In the down part of the crystals there are pyrite, internally replacing chalcopyrite.
An excellent , completely transparent specimen of green spahelrite – cleophane, well shaped isometric crystals. This specimen could be used also as material for cutting – faceting. Part of pictures are taken in transmitted (back) cold LED light.
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“
One nice small fragment of transparent green-yellowish sphalerite-cleophane crystal convenient for cutting – faceting
A very nice, cabinet size specimen, of large cubic crystals, developed singenetically with black sphalerite- marmatite and overgrowth by chalcopyrite. Galena is slightly dissolved.
