Vintage Ribbed Gold-Tone Spratling-Style Spiral Ring

This is a substantial, wide-band cocktail ring featuring a bold yellow gold-tone finish and a prominent nautical-inspired spiral or 'snail' motif. The ring is constructed with a series of concentric, tiered ridges that graduate toward a central circular vortex, creating a three-dimensional sculptural effect. The metal appears to be a cast base metal with a heavy gold plating, exhibiting a warm yellow hue. The interior of the ring shows a textured or pebbled casting surface, which is a common manufacturing characteristic of mid-to-late 20th-century costume jewelry. While no clear designer hallmark is visible from the top view, its form is highly reminiscent of the Brutalist or Modernist styles popularized in the 1960s and 70s, specifically echoing the aesthetic of William Spratling's silver work. Regarding condition, there is visible surface wear including fine micro-scratching and a slight dulling of the finish in the recessed grooves. There are also darker areas of oxidation or patina within the spiral ridges, which provide a nice visual contrast but may also indicate thinning of the plating over time. The structural integrity remains sound with no visible cracks or warping of the band.
