Oval Shell Cameo with Female Profile and Iridescent Background

The item is an oval-shaped cameo, likely functioning as a pendant or brooch given the presence of what appears to be a jump ring or attachment point at the top. It is held in the palm of a hand, suggesting a relatively small, wearable size, possibly between 1 to 2 inches in its longest dimension. The central motif is a carved profile of a female figure, facing right, rendered in a light, possibly off-white or cream material, which stands in relief against a darker, textured background. This background appears to be an iridescent mother-of-pearl or abalone shell, exhibiting a subtle shimmer and varied tones of light gold, green, and pink when catching the light. The carving of the female face exhibits classical features, including a distinct nose, chin, and an elaborate hairstyle with curls or waves pulled back from the face. The details, while not sharply defined, suggest a degree of craftsmanship in the carving technique. The cameo is set within a bezel-like frame, which appears to be a dark, possibly tarnished metal, giving it an antique or vintage aesthetic. There are no immediately visible hallmarks or maker's marks, but the dark patina on the metal frame suggests age and natural wear. The overall condition appears to be good for its age, though minor surface scratches or slight wear to the relief carving might be present upon closer inspection. The iridescent background adds a unique and attractive quality, differentiating it from cameos with solid color backgrounds. The construction suggests it could be from the late 19th or early 20th century, a period when such shell cameos were popular.
