Vintage Gold-Tone Fleur-de-Lis Tie Tack with Mother of Pearl and Security Chain

This is a vintage square tie tack featuring a central circular inlay of white mother-of-pearl or cabochon shell. The bezel and frame are constructed from a gold-toned base metal, likely gold-plated or gold-filled brass. The square face exhibits a fine cross-hatched or Florentine texture, highlighted by raised, decorative fleur-de-lis motifs at each of the four corners, suggesting a Mid-Century Modern or late Art Deco influence, likely dating from the 1950s to the 1970s. The piece includes a functional security assembly consisting of a gold-toned curb link chain attached to a T-bar, designed to anchor the tie through a shirt buttonhole. The metal shows minor signs of surface wear and light patina consistent with age, though no significant plating loss or deep scratches are visible. The central stone appears securely set within the raised metal border. While no visible maker's marks are discernible in the image, the casting of the fleur-de-lis and the precision of the cross-hatching indicate a quality mass-market fashion accessory for men's formal attire. The overall condition is good, maintaining high luster and structural integrity across the primary tack and the chain attachment.
