Skulls
Skulls made of precious stone are famous all over the world. The symbolism of the skull originates from Mexico, where the skulls were uncovered in archeological finds. Mayans and Aztecs used skulls to heal, and these cultures claim that the crystal skull connected man with the superterrestrial world and considered them to be magical tools. This fact supports some intense energy that radiates from the skulls and cannot be grasped.
