Silver-Tone Oval Mother-of-Pearl Shell Pendant Necklace

This jewelry piece consists of a large, oval-shaped pendant featuring a polished mother-of-pearl or shell cabochon set in a silver-toned metal mounting. The centerpiece displays a creamy white luster with natural iridescent gray-blue undertones, typical of nacreous shells. The setting is simplistic with a smooth bezel and a hinged bail attachment, indicating it may function as a locket or a substantial charm. The pendant is suspended from a thin, silver-toned curb or cable link chain featuring a spring-ring clasp. Although no hallmarks are immediately visible on the front, the uniform oxidation and slight tarnish suggest a sterling silver or silver-plated composition. The piece exhibits a mid-to-late 20th-century aesthetic, prioritizing the natural beauty of the shell over ornate metalwork. Condition appears used but good, with light surface scratches on the metal and minor particulates on the chain links. The smooth dome of the shell shows no significant chips, maintaining its reflective high-polish finish. The overall craftsmanship is consistent with vintage costume or semi-fine jewelry production.
