585 yellow gold locking french hook earrings

vintage tulip shape dangle earrings. stamped 585 which means it's 14k yellow gold. when I bought these many moons ago I was told they were tiny diamonds at the bottom however my yesterday is not pinging so either they are too small to test without touching metal or they simply are not. either way they are a great vintage find. it's hard to see but at the top if the tulip are a tiny tiny round sapphire stone. french hook that locks in back so u dint loose them
