Precolumbian Shell necklace-Ancient Peru. 24 inches long-very nice

Up for consideration is a very nice precolumbian shell necklace. It is 24 inches long.

It's made from different shell types. These were all handmade/ hand ground. The shells beads are round, ovoid, disc and tube shaped. These beads are pre Inca from Peru.

If worn, they will get deeper in color. Age is probably somewhere between 500 years old to 2 thousand years old.
