PGM04 Plumbogummite ps. Pyromorphite
A cabinet sized specimen of pyromorphite partially pseudomorphed to plumbogummite. This piece is a nice radiating cluster of elongated, light blue-green hopper crystals. As with virtually all of these, there are a few broken crystals, but the piece is exactly as shown.
In my opinion, these have been the major find of the last several months, first appearing as a few "back of the room" specimens at Denver 2014, with more subsequently available from 2-3 dealers in Tucson.
