Legend has it that as Aphrodite, goddess of love, lay in majestic slumber on the bank of the Indus River, a playful Eros (Cupid) decided to give her an impromptu manicure with one of his trademark arrowheads. Cast asunder, the freshly clipped fingernails rolled down the bank and sank to the bottom of the river, where they were magically transformed by Zeus’ three daughters, The Fates, into splendid black quartz. Thus, ‘onyx’ (a word roughly translated as ‘nail’ or ‘claw’) was born./via:Stones&Findings/
Onyx is a banded variety of chalcedony. The colors of its bands range from white to almost every color (save some shades, such as purple or blue). Commonly, specimens of onyx contain bands of black and/or white.
