From our series of unusual, strange, cool or odd locales for Pyromorphite. A mystery piece since it is unlike any other Mexican Pyromorphite, and with a puzzling (perhaps wrong) locality. Ex John Marshall collection, John obtained this from the Lesnicks mineral dealership in 1992, labeled Sinaloa State, an area not known for Pyro at all. Either this was mislabeled or came from a new find that is since lost. We normally do not handle specimens with uncertain locality details but this is a a quite unusual specimen and very well crystalized so it may be right for someone who wants to do the research The matrix does not match any of the Mexican localities I am familiar with. For the collector of Pyromorphites or Mexican minerals who has everything, or who likes to do the research and get the correct details of this place.
