This small specimen showcases a complex composition of minerals from the Bulgarian Krushev Mine. Its dark base, primarily composed of dark brown to black, translucent sphalerite with a metallic luster, is densely covered with transparent quartz crystals. Among them, the shiny, metallic accents of galena with a silvery-gray color and golden-yellow chalcopyrite stand out, creating a rich contrast of textures and colors. Main features: Complex association of sphalerite, quartz, galena, and chalcopyrite; Contrast of colors and lusters between dark sphalerite, transparent quartz, and metallic ore minerals; Numerous, well-formed quartz crystals covering the matrix; Distinct, shiny inclusions of galena and chalcopyrite.
