Thick 3/16" square chain, measures 25" long. Should go over your head. If not, the ring opens by pushing down on it.
Large, lightly polished, beautiful tooth measuring 3 3/8 on the slant. Colorful enamel, no repairs or restoration. Recovered by a diver in South Carolina. Estimated 2-14 million years old. Double braided stainless-steel loop goes into the root, no wires going around it. So fill the box up.
