Description

A very special find from an almost forgotten mine. This is the very first specimen I've ever seen from that locality. Virtually nothing appearing on the market and only one photo of baryte from there on the German mineralienatlas-site. A broken baryte crystal is attached to the side with the nice covering of marcasite crystals on the good, transparent baryte crystal. I'm not sure if this could be removed without destroying the marcasite. Otherwise a pretty good specimen with only minor edge wear.

Comes with an old label..
