Beautiful watch cuff and matching cuff

This beautiful coral set was passed down to me from my mom. I can’t seem to discover the owner of this hallmark. It looks like a cursive letter M.

After reading many posts on this forum, I am thinking this might be Navajo made around late 80s early 90s? I couldn’t find anything on the internet about hallmark. Maybe because there was a lot being produced? All guesses! I need help haha! Anyone want to give it a try? :slight_smile:

I agree with you, and like you could not find anything on the hallmark.
