Vintage Silver-Tone Mother of Pearl Scroll Brooch

This is a horizontal vintage brooch featuring a large, circular cabochon of Mother of Pearl (nacre) as its central focal point. The shell displays excellent luster and characteristic iridescent play-of-color, shifting between soft pinks, blues, and iridescent whites. The central stone is approximately 1 inch in diameter and is securely held within a silver-toned metal framework. The metalwork is designed in an asymmetrical, flowing Art Nouveau-inspired scroll and wave pattern. It features various 'beaded' or granulated accents along the curves of the metalwork, adding texture and visual interest. The construction suggests a mid-20th-century piece (circa 1950s-1970s), likely composed of silver-plated base metal or sterling silver, though no hallmarks are visible from the front view. The metal shows minor surface wear and light oxidation consistent with age, but no major structural damage or missing components are evident. The craftsmanship is of good commercial quality, with smooth curves and a polished finish that highlights the contrast between the metal and the biological gemstone. The overall design evokes an oceanic or celestial theme, with the round shell piece mimicking a moon or sun rising above stylized waves.
