Possible Navajo,‎ stamped Turquoise and sterling silver ring, size 9!

This is a signed piece, just can't figure out who it might be. It's a stunning piece of turquoise cabochon measuring about 24x11mm.  The back is stamped Sterling with the initials JC. My guess is that it might be a Jessie Claw (Navajo) piece because the artist uses that same marker, but I can't be totally certain.  Size 9. Super comfortable ring to wear.
