Vintage Screw Back Earrings Gold Tone with Blue Gem

Description

These earrings measure about 0.5". I am unsure of the material of the gem. Join marks visible on halo. Light marks. Some wear to screws. Preowned vintage earrings, sold as shown - I am unsure of material type(s) because of this. 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.
