- Wheatley Mine, Phoenixville, Pennsylvania, USA
- Ex. Wayne Thompson
An outstanding Wheatley pyro from this classic US loclality, surely dating to the late 1800s when crystals of such robust form were found. For a thumb, its the best I have seen from here. But moreover, its the best quality you could get, in any size, for the locality.
