Vintage Gold-Tone Costume Ring with Faux Ruby and Rhinestones

This is a decorative cocktail-style ring crafted in a gold-tone metal, likely a base metal alloy finished with gold plating. The ring features an ornate, openwork galleried head with a central oval-cut faux ruby of a deep crimson hue, flanked by two smaller clear round-cut rhinestones. The design incorporates a floral or foliate motif, common in costume jewelry from the mid-to-late 20th century, approximately 1960s-1980s. The metalwork shows signs of significant wear and oxidation, particularly on the inner band and the underside of the setting, where the gold plating is thinning to reveal a darker base metal. This suggest frequent use or exposure to moisture. The stones appear to be foil-backed glass or crystal, as indicated by a slight dulling of brilliance typical of vintage costume pieces. There are no visible maker's marks or hallmarks on the inner shank in the provided image. The shank is a simple tapered band that splits as it meets the decorative shoulders. The craftsmanship is consistent with mass-produced costume jewelry of its era, focused on aesthetic appeal over high-intrinsic material value.
