This is an Indian necklace sent from Scotland by my brother before he passed last year. I don't know anything about it but it is a very strange necklace. He purchased it in the United States before going to Scotland over seventeen years ago. He was a collector of Indian items and this was in his collection. I haven't any idea what kind of teeth they are. It's a good conversation piece. After posting this on Line, a person contacted me and told me that the teeth are elk. Who knew?
