Vintage Gold-Tone and Onyx-Style Cufflink

This is a single men's formal cufflink featuring a classic circular design. The face of the item consists of a polished, flat black inset, likely crafted from either genuine onyx or a high-quality glass or resin composite, encased in a polished gold-tone metal bezel. The item utilizes a 'bullet back' or toggle-style closure mechanism, which is characteristic of mid-20th-century men's accessories. The metal exhibits the warm hue of yellow gold, though without visible hallmarks such as '14k' or 'sterling,' it is likely a gold-plated base metal or high-quality costume jewelry grade. Its construction is sturdy, showing a slightly convex bezel edge that rises to meet the central stone. Regarding condition, the metal surfaces show light micro-scratching and minor signs of oxidation consistent with age and previous use. No significant chips or deep abrasions are visible on the black decorative inlay. The toggle mechanism appears aligned and functional. This piece reflects a timeless, mid-century modern aesthetic, typical of the 1950s through 1970s, designed for formal business attire or black-tie events. The craftsmanship is clean and professional, lacking the ornate filigree of Victorian eras, leaning instead towards the sleek minimalist styles of the mid-to-late 20th century.
