Graduated Givre Glass and Celluloid Bead Necklace

This is a vintage graduated bead necklace featuring semi-translucent, frosted glass beads with internal white swirls, commonly referred to as 'givre' glass. The necklace is constructed with a series of spherical glass beads that increase in size toward the center, anchored by a large focal bead at the bottom. Between each glass bead is a small, cream-colored spacer bead, likely made of early plastic such as celluloid or bakelite. The glass beads exhibit a subtle cool-toned hue, possibly light blue or grey, which contrasts with the warmth of the spacers. The necklace is secured with a simple silver-toned barrel or spring ring clasp. The craftsmanship suggests a mid-20th-century origin, likely 1940s to 1950s costume jewelry. The condition appears fair with visible patina on the metal findings and slight yellowing to the spacer beads consistent with age. There is no visible sign of maker's marks in the image. The overall length appears to be approximately 18 to 20 inches, resting on a purple satin-like background which highlights the translucency and matte finish of the glass components.
