Ring Info/History

Good morning. When my father passed this ring was found and nobody knows anything about it or where it came from. Is there anyone who would be able to tell me anything based on the picture I attached. Thank you. 20220424_095111.jpg

The Centenary Diamond
my Daddy had a ring that looked a lot like that one, at least from the side-view profile of it (any stamps in his had worn away years ago). it's an emerald cut (fake) ruby in a sort of faked bezel setting (reaaally wide prongs). he got it as a gift from a girlfriend when he was in high school in probably... 1961 or 1962.

not to say that's what you've got or how old it is! i have my Daddy's ring, and i wear it every now and then.

which, i realize, doesn't have much to do with your question. sorry!

that B&F stamp is possibly for Baden & Foss? or at least that's what popped into my head. i seem to recall that they did a lot of synthetic / simulated gemstones in yellow gold. off the top of my head i don't know how old, or new, their stuff is. but that's at least a starting point, maybe?
