New Guinea Dani or Highlands Necklace Baler Shell

Up for offer is what feels to be an older status necklace made from hand-woven rope, featuring a baler-shell pendant. Upon closer inspection, the rope necklace looks to either be woven in the same way bilum bags would be or it's made from an old bilum. The shell is approx 8-1/2"L, along the outer surface and the rope seems to be a combination of materials I believe including various kinds of cloth and hand-rolled ropes. My debate is whether this is Dani people from the western highlands of Indonesian Papua or the highlands of New Guinea? Shipping will be $8; $10 to an international destination.
