Size:  61 gram

Weight: 54mm x 30mm x 10mm

Origin:  Olkusz Mine, Southern Poland

This collector's grade polished slice of Olkusz Schalenblende from Poland is a truly remarkable specimen, showcasing both intricate natural patterns and fascinating mineralogical properties. One side is expertly polished to reveal captivating bands of varying shades of brown, grey, and cream, accented by metallic galena inclusions. The unpolished reverse offers a contrasting, raw aesthetic.

Schalenblende is a distinctive mineral aggregate, primarily composed of banded sphalerite, galena, and marcasite. Sphalerite, a zinc sulfide, forms the predominant concentric layers, with its color variations often indicative of trace elements. Galena, a lead sulfide, typically appears as lustrous, metallic grey patches or streaks. Marcasite, an iron sulfide, can be present, contributing to the overall intricate texture.

The formation of this unique material occurs in hydrothermal environments, often within karstic limestone caves. Mineral-rich solutions slowly deposit successive layers of different sulfides, or varying compositions of the same sulfide, creating the characteristic rhythmic banding. The Olkusz Mine in Poland is particularly famous for producing exceptionally well-formed and aesthetically pleasing Schalenblende, highly prized by collectors worldwide. The presence of fluorescent sphalerite in this specimen adds another layer of intrigue, as some sphalerite varieties exhibit luminescence under UV light. This combination of beauty, complex formation, and specific locality makes Olkusz Schalenblende a significant and relatively rare find for discerning mineral enthusiasts.
