Polybasite (excellent old classic) Stoudt Coll.

Item Description

A striking and aesthetic, old-time thumbnail of diverging clusters of parallel-growth, splendent, metallic-gray, pseudohexagonal, polybasite crystals from the Proano Mine at Fresnillo. Tiny calcites on the backside are a nifty accent and the polybasites have a light iridescence. Complete all-around and nearly pristine, with only trivial edgewear and a bit of contacting on one end. Classic and most excellent old material from this historic mine. Ex Dave Stoudt Collection. Seldom available in this quality.
