This is a pair of gold tone pierced earrings with blue and green enameling and a blue lucite cabachon in the center. The earrings are not signed and I do not know who made them. The setting is gold tone. The earrings measure 7/8 of an inch in diameter. They are in very good condition and appear to have been gently worn, if at all. They may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
