Description
A masculine-style sterling silver signet ring featuring a polished rectangular black onyx stone. The ring is distinguished by its intricate openwork gallery, which provides a sense of architectural lightness to an otherwise heavy silhouette. The silver has developed a deep, dark patina that highlights the recessed decorative elements on the shoulders.
Key Features
Integrated openwork gallery, geometric shoulder detailing, and a flat-topped black onyx setting typical of mid-century gentleman's jewelry.
Material & Composition
Sterling Silver (.925) or high-grade Silver Alloy; set with a rectangular cabochon of black onyx. Metal composition likely includes copper as a hardening agent.
Finish & Decoration
Oxidized silver finish with heavy natural tarnish/patina; features cast openwork (pierced) gallery under the stone setting and decorative textured shoulders.
Hallmarks & Stamps
Internal band likely contains a '925' or 'STERLING' stamp. No visible external hallmarks are present in this orientation. Marks are typically located on the inner bottom of the shank.
Construction Details
Lost-wax casting process. The stone is secured via a bezel or integrated prong setting. The shank and head appear to be cast as a single unified piece rather than soldered.
Functional Features
Signet-style flat-top stone for aesthetic use; decorative pierced gallery to allow light through the stone and reduce metal weight for comfort.
Handle & Grip Details
N/A
Craftsmanship Details
Commercial grade casting. The openwork is well-defined but shows some 'flash' or roughness inherent in mass-production molds. Symmetric and balanced design.
Authentication Indicators
Wear patterns are consistent with silver alloy; copper-toning in deep crevices suggests standard sterling oxidation. Casting seams are somewhat smoothed, indicating a mid-tier production quality.
Origin & Manufacturing
Possibly USA, Mexico, or Thailand. These regions are high-volume producers of sterling silver onyx jewelry for the souvenir and boutique trade.
Era & Period
Modern Era; likely mid-to-late 20th century (c. 1960s-1980s). The design draws inspiration from Art Deco geometric motifs but uses modern mass-production casting techniques.
Age Estimate
Circa 1970-1990. The style of casting and the specific wear patterns on the shank suggest a piece that is several decades old but not antique.
Cultural Significance
Represents the democratization of 'statement jewelry' for men in the mid-to-late 20th century, moving away from precious gemstones toward affordable but bold semi-precious silver settings.
Condition Notes
Overall Good condition. Significant surface tarnish and oxidation present. The shank shows minor scuffing and thinning from wear. No visible cracks in the onyx.
Value Estimate
$40.00 - $85.00 USD. Value is based on silver weight and secondary market demand for vintage 'biker' or 'boho' style jewelry.
Care & Maintenance
Clean with a soft brush and warm soapy water to remove debris from the openwork. Use a silver polishing cloth for the outer band but avoid chemical dips which can damage the onyx.
Similar Pieces
Art Deco period onyx rings (usually more delicate/hand-chased) and Contemporary Mexican Taxco silver rings (usually heavier and more modernist).
Interesting Facts
Black onyx was historically used in jewelry to signify mourning, but by the mid-20th century, it became a staple of masculine fashion, symbolizing strength and sobriety.
