A friend purchased these earrings in Taxco, Mexico in the 1980's. They are 1" across and have a small black onyx cabochon in the center of the flower. The earrings are marked Mexico 925 on the reverse. The weight is 8.8 grams total.
The earrings are in excellent condition with slight tarnish that can easily be polished, if you desire. My friend says they have never been worn.
