A cabinet sized specimen of plumbogummite after pyromorphite, with associated pyromorphite that has not pseudomorphed.  This piece features a number of partially pseudomorpheded hopper crystals on the top, on a matrix of pyromorphite and limonite. 

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.
