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. This Vanadinite specimen is from the Mibladen Mining District Mcknes-Talilalat Region, Morocco. 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.
