Video on Instagram Senarmontite is a rare Sb-oxide, and is so uncommon from this mine that there aren't even any pics in Mindat for this location. To say that this rare pseudomorph is dramatic would be an understatement, as the altered Stibnite blades are festooned with CLUSTERS of sharp, octahedral, lustrous, mm-size tan crystals of Senarmontite. On top of that, almost literally, the iridescent patina is absolutely eye-popping. The rich details and dazzling appearance create an artistic and aesthetic combination piece that and exceedingly uncommon on every level. One of only a handful I am aware of.
