Some cufflinks are made for tuxedos, as is the case with the Framed Mother of Pearl Onyx Tuxedo Set. Silver sterling studs include a back that shapes in one direction. The one directional back keeps the cufflinks firmly entrenched in a tuxedo button hole. Onyx and Mother of Pearl present contrasting appearances that elevate the cufflinks to strictly formalwear status. Many fashionistas consider these cufflinks to rank near the top of the high-end design list.
