Need help identifying signature

I’ve got a beautiful heavy Sterling bracelet that I can’t find out anything on the signature. I also need to know what the style is and tribal affiliation. The signature is hard to read but looks like AENZ. I’m attaching photos. Thanks!

Hello, thanks for sharing. I would call this a Navajo bracelet. It is a sandcast style piece. The stones are interesting. You don’t think of Navajo artists working with these small settings, more of a Zuni style. The marking is not an artist hallmark, but a code for how much the bracelet cost. Hope this information helps.
