Strand of Pale Yellow Glass Bead Necklace Strung on Chain

This vintage glass bead necklace which is strung on chain is 8 1/2" hanging length.  The different shape beads make the necklace very interesting.  I have checked all of the beads and find nothing wrong with them.  It fastens with a spring ring clasp which works well.  The chain is darkened with age.  I have not attempted to clean it, I leave that decision up to the buyer.  My guess is that this necklace is from the 1920's - 1930's era.
