Amethyst Bead Necklace with Silver Accent

Amethyst bead necklace with one sterling silver accent bead. Closure is a ribbon tie. Necklace is heavy as beads are large and solid. I've had this necklace for over 10 years and don't recall wearing it, it looks to be in excellent condition overall aside from the cords/ribbon, which may eventually need to be replaced due to the age of the necklace. As you can see one end of the ribbon is frayed and there is some wear to the ribbon where it was tied while stored. The bead portion of the necklace is 15" long, when including the ribbon it is 40" total in length.
