Fine deep green specimen from the type locality, and still the source of the world's best for the species. Very rich example of this species! Note that due to the association this is almost certainly from the find that provided the type specimens, as well.
5 x 3.7 x 1.3 cm. This is a rare philipsburgite from the famous old mines in Utah. These small specks are beautiful. Zalesiite and cornwallite are in association. Ex. Martin Zinn Collection.
2.2 x 1.7 x 1.6 cm. A rich coating of lustrous apple-green crystals on a gemmy Quartz crystal. The Philipsburgite crystals are classic for the type locality - gemmy, rounded to about .5 mm in size, lustrous, and an attractive medium green. On one area they are spread out so they can be appreciated individually, on another part of the specimen they form a dense coating. Ex. Charlie Key.
2.3 x 1.8 x 1.6 cm. 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.
An unusual and showy combination specimen from the famous Black Pine Mine of Montana. Turquoise-green philipsburgite - this is the TYPE LOCALITY, coats a pristine quartz crystal on matrix. Green microcrystallized mimetite and selenite crystals are nicely set on the specimen. This is a RARE COMBINATION piece especially for the mimetite 2.7 x 1.8 x 1.5 cm

Never seen from here , but I am told its legit....this is a rare phillipsburgite from the famous old mines in Utah, probably not identified until after the mineral was found elsewhere and named. These small specks are beautiful - more so than it tends to be from the type locality in fact for lustre and sparkliness, but this is really a locality reference piece.
