PGM14 Plumbogummite ps. Pyromorphite
This piece is primarily pyromorphite with what seems to be either a dusting or an extremely shallow layer of plumbogummite, though it has a small clump of crystals near the top that were farther along in the pseudomorphing process.
I have heard a couple people comment that it's a shame the pyromorphite crystals were pseudomorphed-- that if they were not, they would probably be among the largest and best pyromorphite crystals out there. This piece kind of provides a rebuttal to that assessment-- while they had size, they don't seem to have had the best color.... so the plumbogummite is definitely an improvement.
This is just an odd sample.
