Vintage Zuni Sunface

Vintage Zuni Sunface Signed Georgene Tsadiasi Vintage earrings. They are at least 20 yrs old. The collection came from a man that sold at shows. Earrings measure 2.75 inches. The width measures right under 1 inch on the center of the earrings. They are not marked Sterling that I could find, but they are signed. They have been tested for sterling where I bought the collection from. Original backing they were sold from & sold for.
