A thread on the artist. Interestingly, he’s Navajo working in Zuni inlay style.

A nice example, typical of his imagery. Plenty of things for sale by him, he was or is productive, so it’s easy to find results. I wouldn’t expect it to wind up higher than the stated opening bid, but who can tell. I do see that most pendants are smaller and sell at about $130 ish.
