Turquoise cuff hallmark

Hello,
I lived in Arizona for a number of years near the Sonoran desert and have a great appreciation for the First People’s jewelry artistry. I recently purchased this cuff and would like to identify the artist. It is an attached AP with a design off the bottom of the A, can’t quite make it out. Is there an online registry I can search- thanks,

Doing a quick search for this hallmark, my usual reference page has it as unknown. image

I didn’t turn up anything else, so hopefully someone else on here recognizes it! Good Luck!
