We carry a diversity of Mexican mineral specimens both from purchased collections and from more modern finds.  On the following pages you will encounter crystals from many locations and in many species.  Most are quite aesthetic and normally very reasonable in price however, high quality, damage free specimens of unusual or highly aesthetic species from Mexico have always commanded top dollar.
