Please tell me something, anything about my grandmother's ring!

This is one big ring. I only discovered the initials after I cleaned it. Don’t know the tribe or the artist. The longest side is about 1 1/4". The stone is green and very free form. The size might be 10-11.

Thank you for any help you can give me.

Hello. I just read on Turquoise Skies website that Zuni artists commonly use a soldering pen or embroiling pen to sign their pieces, and the signature/hallmark does look like that. Hope this helps! You certainly have a beautiful ring!:relaxed:
