Vintage Costume Jewelry Solitaire Ring

This item is a small vintage-style ring, likely costume jewelry, featuring a prominent central setting designed for a solitaire stone, which appears to be missing or heavily obscured. The ring is constructed from a base metal, possibly brass or a heavily tarnished silver-colored alloy, with a noticeably weathered and tarnished gold-tone or bronze-patina finish. The setting is elevated in a crown-like or basket-style mount with four thick prongs, which is flanked by two smaller decorative shoulders that may have once held accent stones. There is significant surface wear, including pitting and oxidation, particularly within the hollow areas of the setting and along the shank. The shank is slightly irregular in shape, suggesting it may have been bent or worn down over time. No visible hallmarks or maker's marks are discernible in the current state, but the style is reminiscent of mass-produced jewelry from the mid-20th century. The overall condition is poor, showing heavy signs of age, use, and exposure to the elements, which has resulted in a dull, gritty texture and loss of original luster. Such items were often produced in plated base metals to mimic high-end engagement sets.
