Sterling silver Celestial Crescent Moon drop dangle earrings. With blue sapphires - like and clear stones. I don't know enough about sapphires to identify them as natural or lab grown. In excellent condition. Made in Italy by a designer Dyadema. 0.75" long. Stamped 925 Italy on the posts and on the backs. Also signed Dyadema on each post.
