In the 20th century, skulls made of crystal were showing up, with people claiming to have discovered them, and that they had Mayan or Aztec origins, and were said to have supernatural powers. Well, it's likely these were hoaxes. Not only were no skulls examined found in a documented excavation, all were dated from no earlier than the 19th century.

But fiction follows RuleOfCool, and the supernatural powers attributed to these skulls are plenty for shows.

Also, despite the skulls actually being made of crystal, works of fiction often depict them as skulls that are simply GemEncrusted.
