hahah i chose mine too. But thankfully I said I want to choose, otherwise he'd have just gotten one from tiff&co (cos he like the blue box -____-) and nothing caught my eye there.
Hahaha I KNOW RIGHT! While the element of surprise is exciting, the idea of wearing a ring that you are not super in love with is tough! My BF bought a ring from Tiffany without telling me and when he brought me to the store (at that point i didn't know) I was quite unhappy with most of the designs. In the end he brought me to a private jeweller and I was very happy with my customised ring. But when I found out he had actually another Tiffany ring he bought previously I felt so bad! Don't understand boys and Tiffany....
Anyway I went to JP 3 times and still didn't manage to find a diamond I felt strongly for. In the end went to a private jeweller, great cut, HCA scores etc. so guys, don't feel pressured to go to JP, it's just one of the stops!
