This is a 14k yellow gold bead and natural amethyst bead necklace with a 14k yellow gold filigree hook type clasp.The clasp is hallmarked.
It measures 19.5" and weighs 13.6 grams.
There are a few gold beads with dings/dents. I do not see any damaged amethyst beads.
The clasp works properly and stays closed securely.
Pretty necklace, probably vintage but came from an estate sale so don't know specifics about it.
