I did a search on the Internet and couldn't find anything that spoke to this question, so I thought I'd ask it here. John Wayne frequently wore the same ring in his movies - it looks like it is gold with a ruby stone. He wears it on his left hand. I noticed that he wears it in "Rio Grande" as well as "Rio Bravo." I'm pretty sure I've spotted it in other movies, as well. Anyone know the significance of this ring?
