Wheatley Mine pyros come along very seldom, and when they do, they are often not much more than druses of small crystals. These were found in the mid to late 1800s. But this is an EXCEPTIONAL specimen, with large crystals (for the Wheatley) measuring to over a centimeter in length. These crystals are attractively accumulated at the top of the matrix, with a field of tiny crystals beneath them. What you see on the display face are actually the top ends of a solid mat of pyro crystals that wraps around to the back. The overall fanspray here is about 2 cm, which is incredible for this locality. If you have your Bunker Hill, Les Farges and Chinese pyro but have yet to own a Pennsylvania one, better jump on this, as they just aren't seen for sale very often in this quality. In fact, although this is not the largest specimen I have sold, or the most expensive, I'd clock it as one of the very finest.
