This is a pair of vintage cufflinks. They are not marked. The cufflinks have large grey faux moonstone glass stones. The glass is carved or molded on the sides with a cartouche design. The design is accented with silver tone enameling or paint. The tops of the cufflinks measure 1-1/8 inches square. There is some wear to the accent paint. The cufflinks have not been cleaned or polished. Please let me know if you have any questions. Thanks for stopping by.
