Vintage 1980s Colour Block Guilloche Enamel Gold Earrings

Downsizing my Mother's costume jewelry. Great vintage condition. Shows little signs of wear. Some verdigris - require light cleaning. Due to the unique nature of vintage items, they are being sold as is. Please keep in mind that most antique and vintage items will show wear and imperfections consistent with their age and use. Note : I don't clean vintage jewelry before I sell it. The cleaning is up to the buyer as every collector has their own method. Don't want to devalue it, if something goes wrong. Measure approximately 1" in diameter. The back are NOT original. Questions? Leave a comment below, please.
