I don't know the story of this pendant, but it screams 1970s earth goddess to me, and I really love it! I am also not 100% sure of the metal, but believe it is brass. It's a bit rusted, but I rather think this adds to its charm. Such a great face, with cutout eyes and mouth, and the nose and brows in relief. Surely this would bring good luck and love to its wearer!
2 2/8" in diameter and 3/8" deep.
