Early Native American Beaded Amulet/points/large necklace beads

  

Early Native American Beaded Amulet/points/large necklace beads. I'm assuming these beads went on a necklace and this pendant hung on that and that it was sometime in the 19th century. The pendant is 3 3/8 wide and oobviously missing some of the outer beads which appear to be shell or seeds of some sort. The points are high quality, sharp and thin. These are unrelated items as the points are much older than the pendant but they were kept together for possibly generations and found together by me.
