Vintage Silver-Tone Black Onyx-Style Floral Cocktail Ring

This is a vintage silver-tone cocktail ring featuring a prominent floral or 'sunburst' design. The central focus is a circular, faceted black stone, likely onyx or black glass, held in a classic multi-prong serrated setting. Surrounding the center stone are eleven interconnected wire loops or petals that create a stylized flower head pattern. The metal appears to be a base metal or sterling silver with a slightly aged patina, showing some dullness and minor surface wear typical of mid-20th-century costume jewelry. The construction utilizes a wire-work technique common in the 1960s and 1970s. While no maker's mark is visible from this angle, the aesthetic is consistent with mass-produced vintage fashion accessories. The stone shows relatively sharp facet edges, though there may be microscopic abrasions from use. The band, though partially obscured, appears to be a simple circular shank integrated into the back of the floral face. The craftsmanship is of standard commercial quality for its era, focusing on visual impact and geometric symmetry.

I have conducted a visual examination of this vintage silver-tone cocktail ring. The piece exhibits a mid-century floral design characteristic of 1960s-1970s wire-work costume jewelry. The central stone, while visually consistent with black onyx or jet, appears to be high-quality faceted glass based on the sharp facet edges and the era's common manufacturing practices. The metal displays a dulling patina and surface abrasions consistent with age and occasional wear. While the wire-loop petals remain symmetrical, the lack of a visible maker's mark suggests a mass-produced origin rather than a designer-signed piece like those from Miriam Haskell or Trifari. Currently, the market for unsigned mid-century costume jewelry is stable, driven primarily by vintage fashion enthusiasts rather than high-end collectors. This specific floral 'sunburst' aesthetic is desirable for its bold bohemian look, but its prevalence in the market keeps prices accessible. Factors limiting value include the base-metal composition and the absence of provenance. Limitations of this appraisal include the inability to verify metal purity or stone composition through chemical testing or refractometry. To provide a definitive valuation, an in-person inspection is required to check for hidden hallmarks on the inner shank and to perform a scratch test or thermal conductivity test on the central stone. Provenance documentation, such as original packaging or sales receipts, would also be necessary to elevate the piece beyond the 'unsigned affordable' category.
