Old Pawn Jewelry @ 100 years old

This is a Navajo necklace which is about 100 years old. I bought it from a woman who was in the State Department on the Navajo Reservations for over 50 years. She held this necklace as a pawn for a navajo person, and it was never redeemed. It was common practice for white people on the Res to practice pawning with the natives as that there was no banking system available to them. It wasn't just drinking money that was needed, but necessities of life. The woman I bought this from told me that is was a very old necklace when she acquired it, and that was over 60 years ago.  So 100 years is a conservative guess.
