Vintage Gold-Tone Oval Cabochon Brooch

This item is a vintage oval-shaped brooch featuring a central white opaque cabochon, likely composed of glass, resin, or polished stone such as mother-of-pearl or moonstone. The cabochon is smooth and dome-shaped with a soft milky luster. It is securely bezel-set within a polished yellow gold-tone metal frame. The frame features a stepped or double-rimmed design, adding textural depth and catching the light across its reflective surfaces. Based on its construction and aesthetic, the piece likely dates from the mid-to-late 20th century, possibly the 1970s or 1980s, a period popular for chunky costume jewelry. The metal shows visible signs of age including light surface scratches, minor tarnishing, and slight loss of plating on the outer edges and reverse pin mechanism. The clasp appears to be a standard safety rolling catch. While no maker's mark is immediately visible in the provided image, the weight and finish suggest a quality mass-market costume piece. The overall condition is good, showing expected wear consistent with vintage items, but possessing a classic and versatile design suitable for formal or everyday wear.
