Vintage Clip On Earrings - Layered Blue & Green Diamond Shapes Large Statement

These earrings measure just over 1 & 5/8" long. I cleaned these earrings but the rear has marks/staining/tarnish not sure which. some glue residue around clips.

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.
