Yes, lol. I am having the same problem. I think if the diamond is a little bigger like 1.75 range it would be nice to go with the Novo, since on my small fingers that would look pretty substantial. I tried on a 1.8 Novo at Tiffany's the other day and it was really gorgeous. The size was perfect!
Otherwise for a 1.5, I feel like the halo really takes the stone up a notch!
I like that idea of pairing fun bands with it, if I go for non-halo style! I think I cant go wrong this way, and I could always choose to halo later if I am still feeling that urge!
