Umm.. That's not a ring. It's some kind of finger brace. Go to the 0:55 or 1:07 mark and pause.
While your post gives me some shadow of a doubt, I think you are dreaming or at least stretching.... While it is quite possible I could be wrong, I doubt it.
I'll leave it to someone with a 30 inch monitor to look closer. Doesn't look a bit like a finger brace to me on my 19 incher.
