History and folklore

Onyx comes from the Greek word for fingernail. Greek myth tells that Eros clipped Aphrodite's nails while she slept, and the Fates turned the clippings to stone so no part of a goddess would perish. Banded onyx was carved into Roman cameos and seals. In medieval European folklore, black onyx was sometimes viewed with suspicion, yet it was also worn to steady the mind. Today witches value it for discipline, endurance, and protective strength.
