How can you tell if cufflinks are silver?

To tell if cufflinks are silver, look on their backs for purity marks. Genuine silver pieces may feature “925,” “999,” “STER,” “STERLING” or other markings to indicate their material. If you can't find markings or have difficulty interpreting them, try placing a magnet near the cufflinks. As genuine silver isn't magnetic, a strong attraction to a magnet will usually indicate that cufflinks are a metal other than silver or feature silver plating over a less expensive material. A certified appraiser or experienced jeweler can also aid you in the identification process. On 1stDibs, shop a variety of silver cufflinks.
