An excellent specimen presenting cubic galena crystals overgrowth by transparent green sphalerite – cleophane and quartz
One of the last pieces of Bulgarian famous cavity of transparent sphalerite – cleophane with intensive green-emerald color. The piece is completely transparent, but in its down part, there is a shadow, following the zoning of crystal development of around 10 % of the volume. The picture is taken in transmitted (back) led light.
One excellent cabinet size specimen of very well developed Spinel law twins in Galena, on the top of sphalerite(marmatite) and quartz and pyrite, covered by green color chlorite
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.
