The stone in this piece resembles Jasper and it appears to be authentic. It came off a broken necklace so there is no way to verify this. It's 16" long and uses a base metal copper colored toggle closure attached with my signature decorative knotting. I was able to salvage the round stone beads from the same necklace. I paired it with amber 'peacock' and Aurora Borealis mauve glass beads and 14 amber bicone crystals. $32.23 includes shipping within lower 48 of the USA.
