Vintage Carved Faux Ivory or Celluloid Beaded Necklace

This is a vintage single-strand beaded necklace featuring an alternating sequence of carved cream-colored beads. The materials appear to be an early semi-synthetic plastic, such as celluloid, French ivory, or casein, designed to mimic the appearance of natural elephant ivory. The necklace consists of three distinct bead shapes: elongated capsules with vertical and horizontal cross-hatch carvings, round flattened beads with horizontal grooves, and small smooth spherical spacer beads. The beads possess a matte to semi-gloss finish with a warm off-white or yellowish patina consistent with age. Notable features include the precision of the geometric carvings and the traditional silver-toned metal spring ring clasp assembly. Upon close inspection, the item shows various levels of surface wear, including slight discoloration in the recessed carved areas and minor surface scratches, but no major cracks or chips are visible. There are no apparent maker's marks or hallmarks on the beads or the clasp. Based on the style of the carvings and the hardware, this piece likely dates from the 1930s to the 1950s Art Deco or Mid-Century period. The uniform color and lack of Schreger lines suggest a synthetic origin rather than genuine ivory, though the craftsmanship remains of high quality for collectible costume jewelry.
