Since then, the origins of these “crystal skulls” have been the subject of ongoing mystery and controversy. According to the people who claimed to have discovered the skulls, they date back thousands or even tens of thousands of years, to ancient Mesoamerican civilizations such as the Aztec, Toltec, Mixtec or Maya. Many of those who believe in the crystal skulls’ ancient provenance attribute supernatural powers to the objects, including healing properties and the power to expand a person’s psychic abilities in their presence. Some have linked the skulls to the lost city of Atlantis, or claimed them as proof that extraterrestrials visited pre-Columbian civilizations such as the Aztecs. There are perhaps a dozen of these rare ancient crystal skulls in private and public collections. Some are crystal clear, others of smoky or colored quartz. Some are actual human size and of very fine detail, while others are smaller and less refined. All are believed to originate from Mexico and Central America.
