Lots of marks. It is interesting, you have that mark with a copy right and what appears to be a company, and then you have the symbol hallmark, which is Hopi looking next to the sterling mark (.925). Could not find any of the hallmarks in our books.
Jason, I finally found that this hallmark may belong to a Maybelline Yazzie but I have yet to find out anything about her. I have done multiple searches on the internet and come up with some other rings but now history of her. According to my searches she is Navajo but that’s about it. I do see that Yazzie is a known name in the Navajo nation.
