I was given this turquoise jewelry and I know the clustered cuff is Eva L. Wyaco Zuni piece but it is missing a gem just curious on appraising. Also I have the 2nd cuff with some sort of bird and all that is printed on the back is IHM I believe which I am assuming stands for “Indian Handmade”? The next cuff I have I have no idea what kind it is or what it says on the back. On the back it looks like they signed it but scratched it into the cuff. It looks like to me it says “Made by Jonah Nz” It’s hard saying though because it was signed in cursive. I would like to get an appraisal and some type of identify on these cuffs.
