2 turqouise earrings with unidentified letters inside

Hello!
I have 2 identical earrings , but not mates. different sizes. I have not verified this is real turqouise either. There are letters inside the smaller earring. Can anyone tell me what I have here?
Thanks so much

Looks like it might be Nastacio. I’m not a Zuni inlay expert, but I believe there are many Zuni inlay makers by that name. Hopefully someone else her can say if the signature and style look correct for a specific maker.

It could possibly be Navajo. As well as Zuni I have ring that is very similar inlay and pattern. I’ve been told by everyone it is navajo.
