These earrings are handmade of brass (to simulate gold), and are over 30 years old. There is some etching around the larger loop, as well as on the samll birds. These earrings are the ones in the lower right of the photo below.
Please be aware that these earrings are handmade. The ear wire is somewhat larger than for commercially produced examples, and there is a handmade closure hook at the end of the ear wire. For these reasons, a somewhat larger ear pierce is necessary.
