Onyx was very popular with the ancient Greeks and Romans. The name is said by some to be derived from the Greek work Nux, meaning ‘fingernail’ or ‘claw’ due to the fact that most “Onyx” was a flesh tone color in those years.
The tale is that one afternoon, Cupid cut the fingernails from the divine goddess Venus, with an arrowhead while she slept, leaving clipping scattered amongst the sand and that the Fates turned them to stones. As they were no longer part of the heavenly body, they would still never perish.
