Powder blue colored Plumbogummite has partially replaced lime green colored Pyromorphite. The Plumbogummite has a very interesting skeletal structure. Many of the crystals retain a core of Pyromorphite. The Plumbogummite fluoresces bright green under SW UV and less so under LW (the photos were done under SW).
Flaws: The Plumbogummite is missing in places revealing the Pyromorphite core; most of this is not damage but natural.
