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
An aesthetic specimen presenting pyrite and galena developed on mother rock, followed by very well shaped sphalerite(marmatite0 shiny crystals, covered by rhombohedral crystals of calcite
Very nice specimen showing light dissolution and exceptional step-growing of galena crystals, combined with beautiful chalcopyrite, quartz and sphalerite.
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.
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
Exceptional and very aesthetic specimen presenting flat manganocalcite crystals developed on thin transparent quartz crystals, followed by shiny well shaped cubic pyrite crystals. Some of the pyrites have rainbow effect, due to a thin coating of bornite-covellite as result of the oxidation process.
