Two Navajo "Old Pawn" turquoise rings, one with hallmark

[mazarine99]

I thought I’d post some photos that I have of a handful of the pieces I am interested in learning more about.

Any thoughts or insight would be greatly appreciated.

I’m posting photos of two “old pawn” rings, one of which has a feather hallmark, the other has no hallmark at all. I’m fairly certain these are both Navajo.

Love these! The first looks like Kingman to me, but don’t know on the other, and I think both rings look Navajo.

Is it possible the first stone is SB? There’s so much dark matrix that I assumed Kingman.
