Oval Green Stone Cabochon Brooch/Pendant

The item is an oval-shaped brooch or pendant featuring a large, polished cabochon stone set in a simple metal frame. The stone itself exhibits a vibrant lime green hue with natural variations, showcasing lighter white and cream-colored veins or streaks that run diagonally across its surface. There are also darker specks or inclusions, possibly black or dark green, visible within the stone, which are indicative of its natural formation. The stone appears to be a type of serpentine or possibly a lower grade jade, given its color and striations. It has a smooth, rounded surface characteristic of a cabochon cut, which highlights its natural beauty and minimizes facets. The metal setting is a bright, warm gold color, suggesting it could be gold-plated base metal, brass, or a lower karat gold. The frame is not flush but features a distinctive twisted rope or braided wire design around its entire perimeter, adding a decorative element. This twisted detail provides a classic border to the central stone. The overall construction appears sturdy though simple. No visible maker's marks or signatures are discernible in the provided image. The style suggests it could be from the mid-20th century, possibly 1950s-1970s, which often featured natural stones in less ornate settings. The metal shows some slight patination in the crevices of the twisted design, but no significant damage or wear is immediately apparent on the stone or the setting. The polish on the stone appears intact, and its surface is largely free of major scratches or chips. The item exhibits good craftsmanship for its style, with the stone well-seated within its bezel-like setting.
