Help identify a ring

Hello!
I recently purchased a turquoise ring and cannot identify the hallmark, or, find any similar styles online. I am curious as to the artist, symbology etc. Any help or guidance you could provide would be greatly appreciated!
Purchased at a gift shop at south rim Grand Canyon. I was told it is silver and turquoise from the #8 mine and is Navajo, but no other information was provided. I am new to turquoise and Native American jewelry and am completely ignorant.
I attached pictures of the ring and all marks. I assume the C is a copyright mark and the numbers relate to the quality of the silver.
Thank you in advance for any help you can provide!


Nice ring. I have been to those shops at the Grand Canyon and they have lots of manufactured jewelry from shops like https://www.supersmithinc.com/ and http://www.bgmudd.com. You might send them an image and they can tell you about it. Also, just the one picture shows of the side.

I went back and added some more pictures, that uploader is a little tricky.

The hallmark to me looks like the logo for First American Traders, a shop in Gallup. I didn’t know that they produced jewelry.

925 means it’s sterling silver, which is 92.5% silver.
