First, congratulations on your beautiful new ring! It's really breathtaking.
Honestly ... I do think you're right and it looks like it's "too much" with all three rings. I love the ring by itself, and I love it together with your wedding band, but all three together does look a little "cluttered" to me.
I just received my similar band. Mine is rose gold and ALL diamond.
Your looks very delicate but I agree with the other poster I would put your new band on the outside (closest to your hand) then your wedding ring then ering. I think you are loosing your new band when stacked in the middle.
One of the reasons I want to put it in the middle is because my wedding band and ering don't match perfectly so I was hoping the middle ring would make that not so obvious.
Gorgeous ring!! But I think it gets lost between your 2 rings. I'd like to see it on the outside, next to your band where none of the sapphires are covered. Its soooo pretty!!
