Vintage Art Deco Blue Opaline Glass Beaded Necklace 1930s Opalescent ...

The necklace's design suggests a vintage or antique style, possibly dating back to the Art Deco era or earlier, given the combination of glass beads and a delicate chain. Similar necklaces are described as vintage or antique, featuring blue glass beads and silver-tone chains, dating from the 1930s to the 1950s. The beads appear to be a consistent light blue color, possibly opaline or frosted glass, which was popular in vintage jewelry. The chain is a simple link style, which complements the beads without overshadowing them.
