This is a really nice pair of sterling and onyx earrings. They are screw backs and remind me of squash blossom jewelry although they are set with onyx. The fluted edges make me think of flower petals. They are good sized earrings but not too heavy. They are early ones marked Silver Mexico. Earrings are just a little over 1" top to bottom and in excellent condition. There is a dent in the back of one earring but it does not impact the front of the earring or the look of it. I would guess it was a jewelry box accident.
