This is a pair of vintage sterling silver cufflinks with a pearl in the center. The cufflinks are marked STERLING but I do not know who made them. I have not tested the pearl so I do not know if it is real. The top of the cufflinks measure 3/4 of an inch in diameter. The cufflinks weigh 4.6 grams each. The dark areas in my pictures are simply reflections. The cufflinks 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.
