Description

Classic stuff. Sphalerite as schalenblende contains dendritic lustrous galena crystals. This kind of schalenblende ore was most sought after by collectors - it is called "strickbleiglanz" (knitted galena). A nice example for this variety of sphalerite-galena intergrowth and hard to get nowadays. One side cut and grinded.
