Vintage FACETED CLEAR GLASS BEADED NECKLACE STERLING CLASP 17-3/4" HEAVY

Neck length approx. 17-3/4"
Largest center beads approx. 9/16" diameter
Beads are strung on chain, spring ring clasp is marked STERLING, finding appears to be a replacement
There are tubes inside the beads that the chain flowers through, it appears some of these tubes have worn somehow?, I've shown the issue in photos
There are numerous small flea bite chips on edges of facet beads when looked at under magnification, no large chips or cracks
