I'll be purchasing an engagement ring in the near future. The setting will be white gold with baguette accents down each side. It's a very thick band. I'm aiming for 1.5 carats, but I don't want to sacrifice quality for size so I'm wondering what the visual difference is between a 1.25 carat center stone and a 1.5 carat. Is it significant? If I have to, I'll spring for the 1.5. I'm looking at either a princess or emerald cut. Do either one of those appear larger then the other? Also, my fiance has big fingers, size 9.5 so that's certainly a factor (lucky for me).
