Help with ring ID

I was wondering if anyone knows any info about this ring? ie. Zuni, Navajo, old, or new…that kind of stuff.

The hallmark is almost rubbed off I think.

Thanks!

Hello,

The style of the ring is Navajo and is called chip inlay. However I am not sure about this one. Can you send me an additional picture of the ring that shows the back of the ring behind the inlay. Thanks
