2.5" Blue-Green Plumbogummite on Pyromorphite - Yangshuo Mine, China

This is a beautiful cluster of blue-green plumbogummite that formed after yellow pyromorphite crystals. This mineral association was collected from the Yangshuo Mine that's located in the Guangxi Zhuang Autonomous Region of China.

Plumbogummite is a rare lead phosphate mineral with the chemical formula PbAl3(PO4)2(OH)5•(H2O). It forms in oxidation zones of lead deposits and primarily forms as a botryoidal mass after other minerals. The "plumbo" portion of this mineral's name is derived from the latin word for lead, "plumbum". "Gummi" comes from the gum like appearance that the mineral often displays.

Pyromorphite is a mineral species composed of lead chlorophosphate: Pb5(PO4)3Cl, sometimes occurring in sufficient abundance to be mined as an ore of lead. It forms small, hexagonal crystals ranging from dark green to yellow, to orange.
