Rhodochrosite, chalcopyrite and sphalerite
One beautiful miniature specimen of rhodochrosite, chalcopyrite, and sphalerite.
Sturnitsa mine, Davidkovo area, Smolian region, Bulgaria
Long quartz needles, situated on sphalerite, chalcopyrite and pyrite
2869
Hot from the mine! One very aesthetic specimen of sphalerite, chalcopyrite, and pyrite overgrowth by exceptionally long quartz needles.
Skeletal galena, sphalerite-marmatite, chalcopyrite and pyrite
One perfect, cabinet-size specimen, of skeletal developed galena, overgrowth by sphalerite-marmatite, chalcopyrite, quartz, and pyrite. Galena has rounded crystals, due to desolvation.
Galena on chalcopyrite
One perfect cabinet-size specimen of chalcopyrite overgrowth by well-developed skeletal galena crystals, lately strongly dissolved.
Galena, sphalerite-marmatite, chalcopyrite, pyrite and quartz
One vibrant color cabinet size specimen of oxidized galena followed by chalcopyrite, sphalerite – marmatite, pyrite, and quartz
size 72 x 64 x 28 mm
Chalcopyrite, sphalerite-matmatite, pyrite, galena, quartz and dolomite
#2653
One very attractive large cabinet size specimen of quartz, overgrowth by large chalcopyrite crystals in combination with sphalerite-marmatite and galena. In some parts, chalcopyrite is corroded by small pyrite crystals, which is common in this mine. In the last stages of crystallization dolomite, coated with limonite formed small round crystals of all previously crystallized minerals.

Quartz, chalcopyrite, sphalerite-marmatite and dolomite
One excellent miniature specimen of clear quartz crystals overgrowth by several twined and very well terminated chalcopyrite crystals, followed by black and very lustrous sphalerite – marmatite tetrahedral crystals, covered by round yellow-orange dolomite
An incredible specimen of chalcopyrite, sphalerite-marmatite, galena and quartz
An excellent, large cabinet size specimen of quartz overgrowth by sphalerite, galena and followed by very well shaped chalcopyrite. Galena is strongly dissolved in the latest stages of the mineralization process.
Linarite, azurite, chalcopyrite and cuprite
One excellent cabinet size specimen shows clearly the genesis of secondary copper minerals, formed after erosion of chalcopyrite filled cracks in the mother rock.
