Extremely shiny and well-developed galena crystals overwrought by sphalerite and pyrite, followed by thin transparent quartz crystals
A very aesthetic specimen presenting very well terminated lustrous galena crystals, followed by quartz, pyrite, and sphalerite
A Large and extraordinary beautiful specimen of mirror shiny well-shaped galena crystals, lustrous sphalerite(marmatite) and pyrite.
Giudurska mine, Erma Reka, Zlatograd area, Rhodopes mountain, Bulgaria.
size 165 x 160 x 100 mm
Very nice specimen showing light dissolution and exceptional step-growing of galena crystals, combined with beautiful chalcopyrite, quartz and sphalerite.
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.
Bad picture of an excellent specimen. – in the internal cavity of ore body are found very well terminated flat galena crystals with cubic faces. They are singeneticaly accompanied by lustrous sphalerite and chalcopyrite. Crystallization happened in the internal part of the cavity and crystals are strangely arranged as architecture ensemble showing center of empty spaces
Very attractive small specimen of isometric cleophane crystals on quartz, with excellent transparency and color
A very aesthetic and attractive specimen showing almost full paragenesis set – Chalcopyrite, galena, sphalerite, pyrite, and quartz. The specimen is strongly oxidated – galena crystals lose their luster and chalcopyrite is oxidated with different stage and coated in some places by bornite.
An excellent specimen built large, very well terminated and shiny chalcopyrite crystals corroded by galena, pyrite and sphalerite. On some of the chalcopyrite crystals could be seen „elephant skin“ what is usually sign for internal dissolution and recrystallization – in that case, replaced by galena and pyrite.
A nice specimen formed by several large chalcopyrites well-shaped crystals developed on quartz and overgrought by sphalerite and galena. Oxidation gives to chalcopyrite deep dark gold color
