Vintage Iridescent Black and Champagne Mother of Pearl Shell Chip Necklace

This is a vintage statement necklace composed of polished, irregularly shaped shell 'chips' or shards, likely sourced from Pinctada margaritifera (black lip pearl oyster) and champagne-colored mollusks. The necklace features a striking palette ranging from deep charcoal and silvery grey to creamy translucent champagne, with each piece exhibiting a high degree of natural iridescent luster (orient). The construction involves center-drilled shell fragments interspersed with small, frosted white seed spacers to provide flexibility and prevent the sharp edges of the shells from rubbing together. The necklace is secured with a base-metal silver-tone hook-and-eye clasp, characteristic of mid-20th-century costume jewelry, likely dating from the 1960s to the 1980s. The chips vary in size from approximately 10mm to 20mm in length, creating a dense, textured aesthetic. Condition appears excellent with no visible cracks or significant chips beyond the natural organic irregularities of the material. There is some minor oxidized patina on the metal clasp components consistent with age. The craftsmanship is typical of high-quality souvenir or artisanal shell work, utilizing the naturally reflective properties of nacre to create a dynamic visual effect.
