Vintage Screw On Earrings Turquoise Tone Clear Gem - Heavy Tarnish These earrings measure just over 0.75". Earrings have tarnished and discolored to the front and rear, one is significantly more discolored than the other and presents a noticable difference from the front. I am unsure of the material of the gems, but none are missing. Multiple marks and heavy wear. 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. If you have any questions please feel free to drop me a message.
