This is a vintage Venetian glass bead necklace. The necklace is not marked. It is flapper or opera length and measures 62 inches long. The glass beads are clear with white and gold aventurine swirls inside. I believe they call these sommerso beads. The beads measure 1/4 of an inch wide. There are two small clear gold glass beads and a knot separating the larger beads. The necklace is in good condition with no broken or chipped beads that I could find. It has not been cleaned or polished. Please let me know if you have any questions. Thanks for stopping by.
