Vintage Coro Screw On Earrings - 0.5" These earrings measure about 0.5" long. Some gold tone wear. Some gems darker than others. Preowned vintage earrings, sold as shown - I am unsure of material type(s) because of this, this includes what the gems are made out of. Pictures show different angles for you to review - while I attempt to note any defects, some tarnish/signs of wear may be visible that are not otherwise stated. Earrings are tested and photographed on a thin/smooth earring stand (not included) to show that the screw backs are in working order.
