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.
