Vintage Blue Glass Crystal Bead Necklace

Beautiful heavy blue glass necklace. Only the pearl like beads are not glass the rest is. This is a long 56” single strand. Gold tone push box clasp. Unsigned. There is 1 bead shown in last pic that is broken. It is completely cracked in half the 2 pieces fit perfectly together and it would be easy to put a dab of glue to hold it back together.
