Among the ancients, especially the Egyptians and Chinese were those who attributed this stone different powers, how to preserve the bodies of the deads,  to bring luck and good omen for fertility. In some prehistoric civilizations  it was especially appreciated for its hardness and therefore used for tools, or sacrificial instruments.
It seems to possess the gift of eliminating all the  impure energy  and invigorate especially women.
