Beautifully detailed Art Deco necklace by P.S. Co. (Plainville Stock Company), known for their intricate rhodium-plated filigree jewelry from the 1920s–1930s. This piece features repeating triangular panels with delicate floral and linear openwork designs, linked by small decorative connectors. It measures approximately 19" long, offering a slightly longer fit than typical Art Deco collar styles. Finished in bright rhodium plating that enhances the fine relief details and geometric patterning. The box clasp is decorated and signed P.S. CO. The filigree design closely resembles pieces shown in 1930s Plainville Stock Co. catalogs, including models later used for pendant variations. This example appears complete as originally made, designed to be worn without a center drop. Very good vintage condition with light surface wear consistent with age. The clasp functions securely, and the rhodium finish retains a clean silvery tone with crisp filigree detail. Please see all photos for details. ********************** Please note that vintage items were cherished by a previous owner, and may have been worn.
