The carmel glass looks good enough to eat in this filgree necklase. It measures 15 1/2 inches so would fall on the collarbone. With a spring clasp it would be easy to lengthen it with an extender. Glass square on right (as you face it) has a small chip in the corner and last filigree on right looks like it may have been repaired where it connects to chain. Neither flaw is going to be noticed without close scrutiny. Condition considered in pricing. Czech?
