The name comes from the Greek word ‘onyx’, which means nail or claw. The story is that one day the frisky Cupid cut the divine fingernails of Ven us with an arrowhead while she was sleeping. He left the clippings scattered on the sand and the fates turned them into stone so that no part of the heavenly body would ever perish. True, black isn’t normally the colour one associates with fingernails. (Did Ven us wear Vamp, perhaps?) But in Greek times, almost all the colours of chalcedony from fingernail white to dark brown and black were called onyx. Later, the Romans narrowed the term to refer to black and dark brown colours only.
