Ivory and Bone choker from my shadow box

I picked this up at a yardsale for 1 dollar about 15 years ago. The beads are bone, the pendant is old ivory which is cracking. I am not sure the chord is original, probably not. When I first got it, you could barely make out the carving on the pendant. So I took a bit of charcoal ash and rubbed it in to bring out the detail. Here in the Pacific Northwest there are many Native American craftsmen to go to for info. This is how a Nisqually woman told me how to do it. Of course she made me an offer for it which I turned down.
