Vintage Soft Green Graduated Crystal Glass Bead Necklace

This vintage necklace features soft green round crystal glass beads with bicone spacers. The color of the beads gradually changes to a softer mint green toward the back. The approximate length of the necklace is 17 1/2" and the closure is a barrel clasp that sits a little crooked but does not affect how it wears. 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.
