    This is a ring from my mom in law. It is marked 10K and BOA inside. Trying to identify the maker's mark... Anyone know who BOA is and maybe a rough age? If anyone can give me a good reference book for beginners or website I can go to. I am very new at this :)

      I found a few rings marked BOA but no information on the maker.

      Thank you so much katherinescollections! I haven't been able to find any. I am really new to this so I'm trying to learn key search words online :)

      I was able to find out the maker's mark is actually BDA and it is Budlong, Docherty, & Armstrong. The mark was Patented in 1943 in Providence, RI
