This exquisite necklace is all glass. It is Czech and has the classic Y-shape. The pendant is a large multi-faceted piece set into a metal bezel. All of the beads along the chain are matching. There are tube beads and some smaller flat ones. They all have an opaque core in the center. The chain is about 24" long. The pendant is 1 3/8" x 7/8" and the beads above it add another 7/8" to the length. Necklace has a spring ring clasp but is not signed. The metal shows signs of wear consistent with its age and use. I don't see any scratches on the stone. This 1920/'30's necklace is in excellent condition.
