This fragment of thomsenolite has vugs in it where all the crystals have an ultra-thin coating of an iron oxide. Most of the thomsenolite crystals are broken but the stars of this specimen are the cube-octahedral crystals of ralstonite, all the more dramatic with the coating. I forgot to photograph them! They ARE very nice! There are some nice crystals of thomsenolite, as well!
