Vintage Double Graduated Strand of AB Crystal Glass Beads

This striking vintage double strand necklace features faceted round beads with tiny beads as spacers. These iridescent beads have an AB (Aurora Borealis) finish which really sparkles and catches the light. The approximate length of the necklace is 18 1/2" and the closure is a decorative tab box clasp. My sister-in-law was an avid collector of so many things, jewelry was just one category. She knew everything about each and every one of her pieces but unfortunately she is no longer able to tell us. I'm not an expert - I just offered to help find new homes for her beloved pieces. This is a vintage piece and has evidence of wear that is appropriate for its age. Please examine all photos closely for condition.
