I guess I never really thought about things with a dichotomy like that. While this may be evading the question, I like what I like. Sometimes that includes really big diamonds, but really big diamonds in other settings or on other rings I don't like. So I cannot really classify things as big v. proportional - some big stones look more proportional by virtue of their setting, while others look overdone or ostentatious. I have found myself in love with rings with 1/4 ct stones or with 3 ct stones. So I guess I would vote proportional.
Just how I feel, too. I love my ring and I can carry it off. I don't wear it to "show off" cause I could care less if people think it is real or not. I know it is.
It's like the bracelet I just received. I could have had something a whole lot more bling but as soon as I saw it I
knew it was EXACTLY what I wanted.
