Vintage Monogrammed Tie Bar, Cufflink, and Shirt Stud Men's Formal Jewelry Set

This is a five-piece men's formal dress set, likely dating from the mid-20th century (circa 1950s-1960s). The set comprises one tie bar, two cufflinks, and two shirt studs, though it is notably incomplete as a full tuxedo formal set. Each piece features a square 'cushion' shape with rounded corners. The design utilizes a high-polish gold-toned metal bezel surrounding an inset of polished black material, which appears to be either black onyx or glass enamel. The tie bar and both shirt studs are personalized with an engraved Old English style monogram letter 'C' in a gold-colored finish, while the larger cufflinks remain plain black, suggesting this may be a composite set or a specific variation of a coordinated line. The toggle-back mechanisms on the cufflinks and the spring-tension clip on the tie bar indicate standard manufacturing of the era. Physically, the set shows visible signs of age and wear; there is significant tarnishing and loss of the gold plating on the tie bar's clip and the edges of the cufflink bezels, revealing a duller base metal underneath. Scratches are visible on the black surfaces under close inspection. The craftsmanship is of a mid-market consumer grade, common for brands like Swank, Hickok, or Anson, though no specific maker's marks are visible in the photograph. This set represents a classic example of mid-century masculine accessory design, emphasizing geometric shapes and contrasting color palettes for formal attire.
