Crystal skulls are skulls fashioned out of crystal, usually quartz. They are purported to have originated in pre-Columbian Mexico and South America. There is no scientific evidence to support that claim. Visit http://www.archaeology.org/0805/etc/indy.html to discover more about the history of crystal skulls and research associated with them. Although they may not be as ancient as once believed, modern artisans continue to create and sell them both in Mexico and South America and for the New Age and magico-religious trade.
Their dubious history notwithstanding, crystal skulls are used by many Pagans and magical practitioners for a variety of purposes. They may be used by like crystal balls for divination, to represent the ancestors in honorary rituals, altar decoration, and sympathetic magic, in similar ways for chthonic or underworld gods and as sort of amplifiers of magical energy. They are useful and energetic magickal tools, even if they are “fake”.
