Vanadinite shares the same structure with Apatite and the two share similar crystal shapes at times. Vanadinite is part of a chemical series with two other minerals; Pyromorphite (Pb5(PO4)3Cl) and Mimetite (Pb5(AsO4)3Cl). Vanadinite is separated from pyromorphite and mimetite by its blowpipe reactions. Vanadinite from the M'Fis Mine near Mibladen, Morocco. There are some nice fan shaped selenite blades on this specimen. The bright camera lights make the crystals on this specimen look a little brighter than they appear in normal light. Of course just add a little bright light and Wow. All in all this is a very nice specimen, with very little damage. There is also some nice druzy quartz along the selenite blades.
