VTG Native American Signed Southwestern Army Vietnam, Stone Copper Cuff Rare

I do not know much about this beautiful piece copper handmade very heavy for its size turquoise and green stone, and the yellow stone with the coral in it. I don’t know what stone but this is all handmade and natural. I don’t know the maker, but it is stamped. One piece of turquoise needs to be replaced. I do believe this was made for an army veteran for Vietnam war. I do not know the value of this I never seen a piece like this. I will either list this too high or too low. Pictures are actual you be the judge of condition.
