Thanks for all the input, ladies! I can see the majority are big fans of big rocks.
Keep the opinions coming!
A better resale value is a good point, but I doubt I'd want to sell it or upgrade it in the future. A 2.5 carat is the biggest that I've gone that looks nice on my finger. Also, our jeweler will usually give us whatever we paid for something when we upgrade/trade-in for something new.
A larger solitaire would also be the only piece of jewelry I'd need to insure, which would be approximately $400 a year according to my poorly researched sources that quoted a cost of $2 per $100. Yikes. I've always been wary of accessories that require an investment after you buy them. DH has some watches that need servicing every few years... it drives me crazy.
I haven't looked at this size in real life, but the width of the band is what attracted me in pictures. When the diamonds are smaller, the band is thinner and I don't think it has that "wow" look. Also, I currently have a 3/4 eternity band with blue sapphires; it turns and that annoys me. I was also like "why pay for something no one's going to see?" until I got that ring, lol.
When DH and I are really serious, I will do more "in-store research".
If I decide I want the band, the research can begin that much faster. If I want the rock, then I have to wait a few years.
As far as the size of the stone, I am looking between 2.2 and 2.4 so I won't pay the 2.5 premium.
Too bad for DH that I'm ultra color and size sensitive.

an eternity band with .4/.5 stones seems like overkill also i never understood the concept of having diamonds on the back of my finger where nobody can see it plus i be worried about holding onto things like railing or my laptop. i may either chip the diamond or scratch up the laptop.
if you can afford it why not go for a bigger diamond. it doesnt have to be 2.5ct it can be 2ct. i think once you get up to the 8mm mark the extra .5 really doesnt make a difference.
