Vintage Clip On Earrings Black & Mother or Pearl? Large Retro Statement 1.5"

Vintage Clip On Earrings Black & Mother or Pearl? Large Retro Statement 1.5" These earrings measure about 1.5". I am not sure of the material - shimmers like it may be mother of pearl but I am unsure if it is or if it is manmade. Some glue visible to rear. Some marks to the front black area. Light marks and signs of 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. Earrings are tested and photographed on a thin/smooth earring stand (not included) to show that the clips are in working order. If you have any questions please feel free to drop me a message.
