Pyromorphite Crystal Cluster
Pyromorphite crystal cluster from Daoping Mine, Guangxi Province, China
Measures approximately 1.5 x 1.0 x 1.0 inch
Pyromorphite is named in 1813 from the Greek for "fire" and "form" because after being melted into a globule a sample will begin to take on a crystalline shape during cooling. Typically found as green to yellow barrel-shaped hexagonal prisms, in clusters or as druses on matrix. The individual crystals are often modified or etched, giving a hopper-like appearance. Pyromorphite forms a complete series with Mimetite and many specimens are intermediates between the two.
