Vintage Screw Back Earrings Stunning Bright Blue & Clear Gems

Vintage Screw Back Earrings Stunning Bright Blue & Clear Gems These earrings measure a bit under 7/8". Bright blue almost a turquoise tone. Rear has some discoloration/tarnish and marks. I am unsure of the material of the gems; however, there are none missing. 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. If you have any questions please feel free to drop me a message.
