Genuine Onyx Cuff Links, Classic Round Cufflinks made of alloy metal and electroplated with 14K gold or silver. Perfect for french cuff or convertible cuff shirt. Perfect for wedding prom or all black tie events. We also carry this same product as a formal set. That means we have the matching studs to these cufflinks. Onyx is a natural stone that is scratch resistant and is the jewelry of choice for black tie events. We do carry the same set in approx or faux onyx but the look of a real onyx jewelry is much nicer and it is often worth the additional money for your special event. Genuine Onyx Cuff Links Comes in gift box.
