Blue Necklace, made from natural Tagua and Acai seeds. All pieces are handmade by individual artisans in Peru. Each large Tagua seed is about 1.6" long and 1.1" wide (41mm long x 28mm wide), but on this necklace only seed slices have been used. Due to the nature of nature-made jewelry, colors may differ slightly from one piece to another. String length is adjustable for a tighter or looser fit.
