A cabinet sized specimen of plumbogummite after pyromorphite.  This piece features the desirable blue color, and especially large hopper crystals of pyromorphite (almost 5.5 cm in length!)  Judging by the weight (much lighter than you would expect), this piece is completely pseudod to pyromorphite.  There may be a couple broken crystals, but because there are no green pyromophite cores, it doesn't stand out and 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.  

As with most Chinese finds, the best come out at the beginning, and I consider pieces like this-- with the good blue color and the largest hoppered crystals-- to be in that category.
