Request for help with Hallmark Identification

Hello,

I’m trying to find out who uses the Initials marks GPA on southwestern style jewelry.

I’m searching in many places, and while I’ve found other jewelry with the same initial stamp style and jewelry style, I can’t pinpoint the original artist. Any help is appreciated.

Regards,

Jason

An AI-assisted search comes up empty, beyond the suggestion that the silversmith might be Navajo. It would appear that no one has indentified GPA, or at least no one has posted about it on the interwebs.
