Fluorite with Arsenopyrite (ex Nelson Coll.)
A pair of very gemmy and lustrous, light blue green cubes of fluorite on a matrix of silvery muscovite. The crystal on the left of the photo is complete al the way around. The one on the right has a cleave at the rear that probably ocurred during extraction. The top of the piece also has a group of silvery, slightly irridescent crystals of arsenopyrite at the tip. No damage and spectacular!
