Genuine stone and heishe bead necklace. Heishe or heishi (pronounced "hee shee") are small disc- or tube-shaped beads made of organic shells or ground and polished stones.
It measures 22" long. Unmarked toggle clasp. Not sure if this is genuine turquoise or some other stone. Strung on wire. Great shape! Not a vintage necklace, but not brand new.
