Givenchy Vintage Clip On Earrings

Stamped Givenchy clip on earrings. Appears to be from around the 1980s. Not sure of the material composition. Model ear for size reference! *Missing one back. Other original back intact. Some scuffing/scratches to be expected because of the jewelry age. **this piece has not been authenticated by another party. I am simply going off of the stamping which looks authentic. Please be aware of this when purchasing. Open to offers!
