Yellow Gold Tone Ring with Green Cabochon and Clear Accent Stones

The item appears to be a vintage or antique cocktail ring, likely crafted from yellow gold or a gold-tone base metal, given its warm metallic color. The central feature is an oval-shaped cabochon gemstone, which, based on its deep, rich green hue and smooth, polished surface, is likely jade or a similar green gemstone like chrysoprase or aventurine. This central stone is bezel-set or semi-bezel-set within the metal band. Flanking the central green stone are multiple smaller, clear, round faceted stones, possibly diamonds or cubic zirconia, set into the metalwork. These smaller stones exhibit some sparkle, suggesting they are either good quality simulants or genuine gemstones that could benefit from cleaning to enhance their brilliance. The overall design features a gently twisted or undulating band on either side of the central setting, creating an elegant, somewhat organic flow. The metal shows some signs of wear, including minor surface scratches and possibly some tarnish or dirt buildup in the crevices, consistent with age and regular use. There are no immediate visible hallmarks or manufacturer's stamps from the provided image, which would typically be found on the inside of the band. The craftsmanship appears to be of decent quality, with the stones well-seated, though the exact setting type for the smaller stones is difficult to ascertain precisely. The ring's design suggests a mid-20th century to late-20th century aesthetic, possibly falling into the Art Deco revival, Retro, or mid-century modern periods, given its blend of classic and slightly bolder elements. The visible condition suggests it has been worn but is generally intact, with no obvious major damage like missing stones or significant structural deformation.
