onyxyoudaoicibaDictYouDict[onyx 词源字典]
onyx: [13] Greek ónux meant ‘claw, fingernail’ (it is distantly related to English nail). Certain sorts of onyx are pink with white streaks, and a resemblance to pink fingernails with their paler crescent-shaped mark at the base led the Greeks to name the stone ónux. The word travelled to English via Latin onyx and Old French onix.

onyx (n.)youdaoicibaDictYouDict
mid-13c., from Old French oniche "onyx" (12c.), and directly from Latin onyx (genitive onychis), from Greek onyx "onyx-stone," originally "claw, fingernail" (see nail (n.)). So called because the mineral's color sometimes resembles that of a fingernail, pink with white streaks.
