Vintage Black Stone and Gold-Toned Clip-On Earrings

A pair of vintage clip-on earrings featuring a central oval-shaped black stone, likely not a precious gem, set within a gold-toned metal frame. The frame is designed in a stylized, flowing shape that partially encircles the stone, creating a sleek and modernist appearance. The metal has a slightly aged patina, suggesting brass or a similar base metal with gold plating or wash. The stones appear smooth and polished with some minor surface scratches visible under close inspection, indicative of wear consistent with age. The clip-on mechanism is attached to the back of the metal frame, allowing them to be worn without pierced ears. There are no visible maker's marks or stamps on the front or back of the earrings, and it's difficult to determine the exact manufacturing process without further examination. The design suggests a possible mid-20th-century era, likely from the 1950s or 1960s, aligning with the popularity of clip-on earrings and abstract jewelry styles. Overall condition appears fair, with surface wear and aging consistent with vintage costume jewelry. The craftsmanship is likely mass-produced given the lack of distinctive unique features or hand-finishing details. The simple yet elegant design allows for versatility in wear.
