Would like to know information on some of my jewelry? Is it authentic ? Who is the maker?
The best thing about Zuni artists is that they tend to make the same thing over and over, which is really helpful with a google search. You are just basically looking for the exact ring and hoping to gather information that way.

Did find this one, has similarities to yours and differences. However, it looks like the etched name on yours starts with an E. I don’t see the mark that well but compare it to this one.
Formally it’s identical (though with different stones in the inlay positions) to this one by H. Esalio. Can’t tell if yours also has a pendant bail on the back.
