GREEN PYROMORPHITE SPECIMEN
A dark Green Pyromorphite Specimen. Completely covered with crystals on both sides of the specimen, some almost moss-like in form. A very nice example and a colourful addition to the cabinet. Pyromorphite is a very collectable and variable mineral, an essential for any collection. This specimen must be seen under magnification to fully appreciate it.
Pb5(PO4)3Cl , Lead Chlorophosphate.
Pyromorphite shares the same structure with apatite and therefore crystals of the two will have similar shapes. Pyromorphite also forms a chemical series with two other minerals. Mimetite (Pb5(AsO4)3Cl) and Vanadinite (Pb5(VO4)3Cl). Green Mimetite or yellow Pyromorphite can make identification between the two difficult, but usually pyromorphite is green and Mimetite is yellow.
