Heishi (say 'hee-shee') beads are usually made from organic shells or ground and polished stones. Heishi is possibly the oldest form of jewelry in North America. This 17" turquoise Heishi bead necklace is accented and decorated with dark rolled jet beads. It will add just the right accent to your wardrobe and bring compliments every time! The hook-and-eye closure is sterling silver.
