Cameo earrings Costume Jewelry for cameo lovers

Here is a delightful set of vintage cameo earrings. This delicate set was from an estate sale and I have no info on it and there are no markings that I can see. I think it is probably circa 1970s or 80s. It's costume jewelry but has the weight and feel of quality. Anyone who loves cameos will adore this set. Shipping is included in the price :)
