The crystal skulls are human skull hardstone carvings made of clear or milky white quartz (also called "rock crystal"), claimed to be pre-Columbian Mesoamerican artifacts by their alleged finders; however, none of the specimens made available for scientific study has been authenticated as pre-Columbian in origin.
The results of these studies demonstrated that those examined were manufactured in the mid-19th century or later, almost certainly in Europe during a time when interest in ancient culture was abundant. Despite some claims presented in an assortment of popularizing literature, legends of crystal skulls with mystical powers do not figure in genuine Mesoamerican or other Native American mythologies and spiritual accounts.
The Crystal Skull is like a magnet that can attract metal objects, if a person is holding the the crystal skull it can grant the users psychic powers like mind read, but there is a down side to it once the victim holds the crystal skull even longer the victim will lose his/her sanity. So in order to remove the effect try dousing the crystal skull with that neutralizer, then put it in a metal crate.
