Schalenblende (classic locale)

Item Description

An artistic and sculptural trio of polished schalenblende slabs from this well-known Poland locality. Schalenblende is the striking concentric layers with reniform surfaces consisting of alternating bands of sphalerite (brown to yellow), marcasite and galena (grey inclusions). Wurtzite (as often reported to be a component of the Polish Schalenblende) could not be detected by XRD analysis, according to a report. The color variation of the sphalerite is due to grain size and (minor) to the iron content. It is regarded as a classic lapidary material. 142 grams total mass.
