Help! sterling and turquoise ring-delvin nelson?

I have a ring that is signed “DJN” in script, and I was wondering if it was by Delvin Nelson. I have seen Navajo pieces of his before, but I have not seen a ring, and I have never seen his mark in cursive. Can anyone tell me more about the ring, or the artist, or who the real artist may be? Thanks!

Just sold a Delvin Nelson Watch Tips set with a Peyote Bird in similar crushed turquoise and coral inlay fashion as your Dancer, is it? He used the sun rays, sets of three dots and ‘(((’ stampings (to simulate motion it looks like). His initials are stamped on each piece as DJN but are straight up block lettering. Not to say his marks didn’t change like many do. I’m no expert but it sure seems like you have a Delvin ring. Jason’s the expert! Check out my two pics.
