Vintage Enamel and Faux Turquoise Decorative Button

This item is a circular decorative button or upholstery tack measuring approximately 15-20mm in diameter. It is constructed from a gold-toned base metal, likely brass or bronze-finished alloy, featuring a domed profile. The center features a bezel-set cabochon with a mottle-blue matte finish, simulating turquoise or glass. Radiating from this center are eight cloisonné-style sectors divided by metal ribs. Each sector is filled with small, honeycomb-like depressions containing light blue and green enamel or resin. The overall aesthetic suggests an Neo-Egyptian or Art Deco revival style, common in Mid-Century costume jewelry or high-end haberdashery. The metal shows significant signs of age and patina with dark oxidation in the crevices. Several enamel cells appear to have slight loss or discoloration. The craftsmanship demonstrates a mass-produced yet detailed press-molding process typical of the early to mid-20th century. No visible maker's marks are present on the front surface.

Based on my visual examination of this vintage button, I assess it to be a mid-20th-century decorative component, likely utilized for costume jewelry or high-end upholstery. The construction appears to be a stamped brass or alloy base with a 'cold enamel' or resin fill rather than true vitreous kiln-fired cloisonné. The central cabochon simulates turquoise but lacks the matrix and luster of the genuine stone, pointing to glass or early plastic. The aesthetic is distinctly 'Egyptian Revival,' a style that saw surges in popularity in the 1920s and again in the 1960s/70s. Given the press-molding quality and the specific oxidation patterns of the base metal, I lean toward a dating of circa 1960s-1970s. The condition is fair to good; there is notable verdigris and darkening in the recesses, which adds vintage character but indicates exposure to moisture. The enamel work shows minor surface wear but remains largely intact. Technically, this is a mass-produced item rather than fine jewelry. In the current market, single buttons of this caliber are generally sold as 'craft components' or reliable replacements for vintage garments. Values are modest. While a complete set of these buttons on an original card could fetch upwards of $50-$60, a single loose example holds nominal value. Limitations: Without physical handling, I cannot confirm the material of the center stone (glass vs. phenolic resin) or test the metal content. An in-person inspection would allow for a 'hot pin' test on the center stone and a loupe examination to verify if the coloring is true enamel or painted resin, which would marginally adjust the value.
