Vintage Black Enamel Goldtone Wing Shaped High-end Clip-on Earrings

Downsizing my Mother's costume jewelry collection. Elegant clip-on earrings, made of golden and enamelled metal and have a beautiful shape reminiscent of a wing. Unsigned Monet, perhaps. Excellent pre-owned vintage condition with little to no signs of age and wear, except minor tarnish on the back near the clip. Might require light cleaning/polishing. Please be sure to look closely at all pictures as I do try to capture the item's condition, so that you may see any marks or flaws and make an informed decision. 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 1.25". Questions? Leave a comment below, please.
