One amazing and very aesthetic cabinet size specimen of large pyrite cubs overgrowth by tetrahedral small sphalerite-marmatite crystals, followed by galena crystals, lately strongly dissolved to an amorph shape. Pyrite crystals were also under oxidation and are coated by bornite-covellite, which shows a beautiful rainbow effect.
Тип минерал: pyrite
Mirror skeletal galena, sphalerite-marmatite, chalcopyrite and pyrite
One exceptional cabinet size specimen of extremely lustrous – mirror shiny skeletal galena crystals, with very interesting rectangle contact of flat plate crystals with cubic symmetry, developed on the top of also very lustrous sphalerite-marmatite, with chalcopyrite and pyrite.
Pyrite, sphalerite-marmatite, galena and quartz
One excellent specimen of 2 very well terminated clusters of pyrite crystals, with bright lustrous crystal faces, developed on black opaque sphalerite – marmatite, and flat skeletal galena crystal, followed by quartz. Size 42 x 40 x 20 mm. The 9-th of September mine, Madan, Bulgaria
Galena, chalcopyrite, pyrite and quartz
An excellent cabinet size specimen of galena, overgrowth by chalcopyrite tetrahedral crystals. The chalcopyrite is internally dissolved and replaced particularly by pyrite – small pyrite crystals cut the surface of the mother chalcopyrite crystals. The second generation of a galena-bearing solution formed a large galena crystal, which covered most of the chalcopyrite crystals, but some of the ends of these crystals stay out. At the end of the crystalization process, the white quartz overgrowth all of the early formed crystals.
Rainbow pyrite
An exceptional, aesthetic, cabinet size specimen of pyrite coated by bornite and covellite and showing incredible color play.
Sphalerite-marmatite, galena and pyrite
A very attractive, aesthetic specimen of galena and pyrite lustrous crystals, overgrowth by extremely lustrous, well-shaped black sphalerite crystals with tetrahedral habit. In marmatite, there are several twinned crystals.

Galena, sphalerite-marmatite, quartz, chalcopyrite and pyrite
One stunning large cabinet size specimen of black, lustrous sphalerite-marmatite large crystals developed on clear quartz, overgrowth by very well crystallized galena crystals – a combination of cub and octahedron, with mirror lustrous crystal faces. Galena is overgrowth by large chalcopyrite crystals, lately dissolved and replaced internally by small pyrite crystals.
Rhodochrosite, quartz, pyrite, galena, sphalerite and stilbite
An outstanding cabinet size specimen of pyrite, galena, and sphalerite overgrowth by small clear quartz crystals covered by rhodochrosite. At the end of the crystallization process, on top of all minerals were developed small double-terminated stilbite crystals.
Transparent green sphalerite- cleophane, galena quartz and pyrite
#1787
One amazing, large cabinet size specimen of cubic galena crystals, strongly dissolved and rounded, overgrowth, by small quartz clusters, pyrite and very aesthetic transparent isometric sphalerite – cleophane crystals with green color.
