Three vintage polished stone agate necklaces

This group of necklaces are from my aunties collection. She travelled extensively in the PNW and Southwest and would pick up these stone necklaces during her travels. I have no clue the exact stones, thus I am generically calling them agates. These are from the late 60’s.
