that's how I know which setting to get already
she told me to pick the diamond, but like most women she likes big, shiny and flawless and after looking $5500 won't buy big shiny and flawless. I found a nice 1.09 ct on blue nile with g color, si1 and ideal cut for $4750. I still need to look at them for myself in a store but i want to have some knowledge behind me.
Generally, SI1 is considered below engagement ring grade. VS2 is traditionally as low as you would go, but hey, we're not all made of money. Of the four C's, if you're on a budget, clarity is what you would sacrifice first, because that is easily the least visible C to the naked eye. A lower clarity rating will hurt future resale value, but that's about it (unless your future fiance works in a lab and is really going to put it under a high power or electron microscope

). As others have mentioned here, Cut is really the most important, without a good cut, the diamond will simply not sparkle and will look lifeless. Next I'd consider color or carat based on what you think your SO will want more. I can tell you that color is actually quite noticeable when two grades apart (i.e. D vs F, or E vs. G). Carat is less noticeable (in a round diamond) unless you're talking about a difference of a 0.25 carat or more, as much of the diamonds mass is below the surface. The setting may also influence how large the diamond appears to be. Bear in mind that sometimes, certain price premiums may come into play as you approach each carat increment that drives the price up substantially, so you might want to consider buying a carat size slightly less than the next increment to save a little money (i.e. buying a diamond .90-.99 carats instead of 1, 1.75-1.99 instead of 2, etc.) if any of those are similar quality and available.
Good luck!
