Description
Very interesting botryoidal marcasite. It is a nice specimen from an unusual locality showing lots of lustrous, iridescent marcasite crystals.
I am not quite sure when it was found, but the only ones I can find on Mindat that looks like this are from level 190-N, found in the year 2000. That should match pretty well when my father traded this one.
