Vintage Sarah Coventry Serene Gold Tone Faux Pearl Leaf Clip on Earrings

Vintage Sarah Coventry Serene Gold Tone Faux Pearl Leaf Clip on Earrings. In gently preowned condition: there is a green tint in some spots of the gold tone, especially within the filigree work. I cleaned them with vinegar but some faint green still remains (see all close up pics). Stamped SARAH COV. For non pierced earrings. No precious metals or stones.
