Hematite was used by the ancient Egyptians as a amulet of protection against madness. It is sometimes called "the lawyer's stone" believed to bring favorable judgments to the wearer involved in a court case. This belief dates to the Babylonian author Azchalias that wrote that the stone would aid in petitions to the King and victorious in lawsuits. It is an excellent stone to bring about self-control.
