Bright, translucent, emerald-green botryoids richly coat the quartz matrix of this unique and exceptionally fine thumbnail specimen of the rare phosphate philipsburgite from the Type Locality - the Black Pine Mine, Philipsburg Area, Montana. The bulk of the philipsburgite actualy lies on the base of a very sharp, iron oxide-coated quartz crystal. Very uncommon in this quality. Ex. John White Collection. This is certainly the style found from the type pocket, as well, I am told.
