These vintage Mexican sterling silver cufflinks showcase the clean geometric styling that made mid-century Mexican silver so highly regarded by collectors. Measuring approximately 1 inch by 5/8 inch, each cufflink features a polished black onyx inlay set within a sculptural sterling silver form, creating a striking contrast between deep black stone and bright silver. The elongated diamond-shaped profile offers a refined modernist aesthetic that remains timeless for both formal and contemporary wear.

Each cufflink is marked STERLING and bears the desirable Mexican Eagle 3 assay mark, placing their manufacture within Mexico's renowned Eagle hallmark period.

The original fixed-back fittings remain intact and operate properly, preserving both their functionality and period character.

The cufflinks remain in very good vintage condition with light age-appropriate wear consistent with careful use. The sterling has developed a pleasing natural patina, while the black onyx retains an excellent polished finish. Their understated elegance makes them an outstanding addition for collectors of vintage Mexican silver, modernist jewelry, black onyx accessories, Mid-Century design, or distinctive gentleman's cufflinks.
