Vintage Blue and Gold-Tone Flying Bird Cloisonné Earrings. All earrings in my collection were personally purchased between 1980 -1985 and most were worn and loved. These have gold-tone backs and silver colored hooks. The Cloisonné front features a blue background with a bird that is blue, purple and peach. The back is gold-tone with no brand name stamped. Decorative box not included. I always consider reasonable offers or bundle and save.
