The last of the best specimens of emerald green sphalerite (cleophane). This color appears just once in 30 years history of Androvo mine in Erma Reka. It was a small cavity with just several kilograms of excellent transparent sphalerite crystals with deep emerald color. The material was perfect for faceting and at the moment just several hundred grams left. So far this is the only described deposit with this color. There were just few mineral specimens and I have a luck to own more of them, so this is the last small specimen from that cavity. Sphalerite is developed on the top of galena crystal.
Very attractive small specimen of isometric cleophane crystals on quartz, with excellent transparency and color
A single isometric transparent green sphalerite on quartz.
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.
Excelent aesthetic specimen presenting deep green color well terminated shiny izometric sphalerite(cleophane) crystals on quartz baze
Exceptional specimen presenting deep green colored izometric sphalerite (Cleophane) crystals on quartz. Specimen has cleophane crystals on bought sides
Very showing specimen build by galena and pyrite overgrought by quartz,chalcopyrite and large translucent sphalerite crystals. Due to dissolvation proccess, galena has a shiny relief showing „fingerprint surface“
Very aesthetic large specimen showing pyrite and quartz on mother rock, followed by well terminated shiny transparent green cleophane ( sphalerite) crystals and by small and lustrous second generation pyrite crystals.
Exceptional, completely transparent specimen build with isometric transparent green sphalerite crystals on the mother rock
Spectacular specimen showing galena and transparent green sphalerite – cleophane – well terminated shiny crystals overgrought by quartz and small chalcopyrite crystals
