Vintage Gold-Tone Mother of Pearl Collar Bar with Chain

This is a vintage men's sartorial accessory known as a collar bar or collar stay, designed to hold the points of a dress shirt collar together and lift the tie knot. The piece is constructed from a gold-toned metal, likely brass or gold-filled base, featuring a polished finish. Its primary design element is a square-shaped, rounded-corner decorative focal point inlaid with white mother of pearl. This inlay is bisected by a thin gold-tone diagonal bar, adding a geometric Art Deco or mid-century aesthetic. Two lengths of fine curb link chain connect the decorative element to the main functional bar. The main bar utilizes a tension-clip or slide-on mechanism, characterized by a loop-back wire construction that provides the necessary grip for fabric. The overall length of the horizontal bar is approximately 2 inches. In terms of condition, there is visible surface wear and minor tarnishing consistent with age, particularly along the edges of the metal and the chain links. The mother of pearl shows good iridescence with no apparent cracks, though there is some accumulated grime in the recessed areas where the stone meets the metal bezel. No manufacturer hallmarks are immediately visible in the image, suggesting a produced item from the mid-20th century (circa 1940s-1960s). The craftsmanship is characteristic of mass-market gentlemen's jewelry from that era, prioritizing functional elegance.

Based on my visual examination of this vintage collar bar, I have determined it to be a mass-market sartorial accessory dating from the mid-20th century, likely the 1950s. The piece features a gold-tone finish with a mother-of-pearl inlay. My inspection reveals moderate surface wear and oxidation on the tension bar and curb chain, consistent with its age and use. The mother-of-pearl remains intact with pleasing iridescence, though there is notable debris accumulation in the bezel setting that requires professional cleaning. The aesthetic—specifically the diagonal bisection of the square stone—points to an Art Deco-influenced mid-century design. The market for vintage men’s 'small' accessories remains stable but niche; while there is consistent demand from enthusiasts of classic menswear, the lack of a prominent maker's mark (such as Swank or Hickok) limits its value relative to designer-signed pieces. The value is driven primarily by its functional appeal and the current trend in 'neo-vintage' styling. Factors limiting the value include the visible tarnishing and the use of base metals rather than solid gold. Authenticity cannot be fully verified through digital images alone. A physical inspection is required to test for gold content (acid or XRF testing) and to inspect for manufacturer stamps hidden within the tension mechanism. Provenance documentation or original packaging would significantly enhance its collectible status. I have based this valuation on current secondary market sales of unsigned men's jewelry in similar condition.
