Vintage Gold Tone Ring with Green Cabochon

This item is a vintage-style ring featuring a central green cabochon stone set in a gold-tone metal band. The stone itself appears to be a rounded, polished, opaque green, possibly jade, nephrite, or a similar stone, exhibiting a consistent color without prominent inclusions visible from the image. It is secured by prongs or a bezel setting that is partially obscured by the stone's elevation. The band of the ring displays a delicate, openwork design, characterized by intricate scrollwork or filigree patterns on the shoulders leading up to the central setting. This detailing suggests a craftsmanship that is either artisanal or machine-made to mimic a more handcrafted aesthetic. The metal has a warm, yellow-gold hue, indicating it is likely gold-plated, gold-filled, or a lower karat gold alloy, as distinguishing definitively from the image is difficult. The ring appears to be in good condition for its presumed age, with no apparent dings, major scratches, or missing elements from the setting or band visible in the somewhat blurry image. The overall style points to an earlier to mid-20th-century aesthetic, perhaps Art Deco or Mid-Century Modern inspired, given the ornamental metalwork and simple cabochon setting. There are no discernible maker's marks or stamps evident from the provided image. The ring is worn on a thumb, suggesting it is a larger size, or it could be worn on any finger if it's adjustable or a specific size. The quality of craftsmanship appears good for a piece of its type, prioritizing aesthetic detail in the band without overly elaborate stone work.
