hi everyone, i'm back! my original post was from almost a year ago! i decided to keep both rings as my wedding ring...and i'm now a mrs.

yay! my 30th birthday is approaching and i'm so itching for another ring for my stack

i'm not as in love with both of these rings together as i think it's just way too much diamonds so now, since my birthday is coming up, it's a perfect excuse for me to get something that would "spice" it up a little more!
do you have any suggestions? i know a lot of you have good tastes, that's why i'm here! below are some of my choices, please let me know what you think, i could really use some honest and great opinions! TIA!
here are my current rings for reference
