Such a pretty vintage Vendome necklace and earrings: purplish blue art glass beads, pale blue aurora borealis crystals, and white glass beads with a aurora borealis finish.  The double strand has a pretty goldtone closure.  It measures 15 1/2" long including the extension chain.  The matching clip on earrings are marked Vendome on the back as well as the hook on the necklace. Very good vintage condition.
