Pyromorphite    Phoenixville, PA.  Ex. Jim Turek collection.  Classic east coast specimen in an unusually large and well formed piece.  Crystals to .8 cm many of which are hollow.  6.4 x 4.4 x 4.6 cm overall.  There is more damage than I'd prefer to see but this is still a desirable piece for its size and density of crystals.  400$ on sale for $280
