This item was purchased at an auction so the details are unknown. The Choker resembles the apache and/or Navajo style craftsmanship. The straps are made of leather and the white long beads look to be buffalo beads because they match other similar chokers. The red long beads look to be hairpipe or cherry pipe beads as seen in other chokers. The silver beads are probably stainless steel as they are magnetic. The arrowhead appears to be made of Jasper. The very end of the tip looks broke off as seen in the pics. Im not making any absolute claims on the materials used in this item. please look at the pics and do your investigating on the materials used.
