Description
This is an old-time, sculptural specimen with Schalenblende and Galena from classic Diepenlinchen Mine of Stolberg near Aachen. And here we have stalactite-reminiscent aggregates of botryoidal Schalenblende with beige colour and satin luster. Schalenblende is a fine grained mixture of sulfides, dominated by Sphalerite of a mid brown to yellow or cream colour, occurring in concentric layers with reniform surfaces which also may contain intergrown, Marcasite, Pyrite, Galena and possible Wurtzite. It is believed to have formed by relatively rapid crystallization of a low temperature sulfide gel. All vugs of this highly interesting specimen are scattered with tiny metallic Galena crystals. This superb specimen comes with a fine antique label.
