crystal skull

crystal skull
A crystal skull is an artifact in the form of a human skull, most often made of clear rock quartz crystal, but that may alternatively be composed of amethyst, rose quartz, smoky quartz, alabaster, topaz, moonstone, tourmaline, ametrine, citrine, sapphire, or agate. A variety of such skulls, some 50 in number, have been discovered in parts of Mexico and Central America; they have been found in a variety of sizes, from that of a grapefruit to larger than life-size, and have ages up to 1,000 years or more. The exact purpose and origin of the skulls has yet to be determined, but it is thought that they would have had some religious significance to the people who created them, because most of them have been found in tombs.
