Vintage Art Deco Style Blue Thermoplastic and Silver-Tone Costume Jewelry Set

This vintage costume jewelry parure includes a choker-length necklace and a pair of matching clip-on or screw-back earrings, designed in a distinct Art Deco Revival style. The set features repeated geometric fan-like motifs, each consisting of a silver-toned metal framework with three radiant lines flanking a central triangular insert. The inserts appear to be made of a matte, navy-blue thermoplastic or Lucite, characterized by a smooth, domed finish that catches the light with a soft satin sheen. The construction indicates mid-20th-century craftsmanship (circa 1950s-1960s), which was a period known for high-quality plated costume pieces. The metal exhibits a polished silver finish, likely rhodium or chrome plated, which has maintained its luster with minimal visible tarnishing. Each link in the necklace is connected by strong metal hinges, leading to a classic oval-link extender chain ending in a small metal bead. Condition-wise, the set appears excellent, with no missing stones and all plating intact, though minor surface scratches on the plastic inserts are consistent with careful vintage use. The 'Art' brand mentioned in the context refers to the manufacturer Mode Art, known for its intricate designs and high sculptural quality, which is evident here in the depth of the metal casting and the precise fit of the blue cabochons.
