The cut and clarity were pretty irrelevant when I looked. The color is pretty important though. Some of the lower tier stones look pretty yellow and it's very noticeable.
This. Really depends on the cut too. (EDIT: my wife’s friend was engaged to some douche who got her this monster rock. She was showing it off and there was a large black fleck of something in it that couldn’t be missed with the naked eye ?. Pretty sure it was over 2 carats) I read all sorts of articles that said I could get away with a G color stone in an emerald cut. I got it from blue Nile and everything looked good. I did the refrigerator light test and it looked visibly yellow. So back it went, I dropped .05 carats and went from a G VVS1 to an E VVS1 and I think it was a few hundred dollars more but well worth it. Nice thing with the emerald cut is that I dropped .05 carats but the new stone is actually fractions of mm larger in length and width but loses a bit in depth.
You’ll find that the price bump at 1.00 carats is pretty extreme and not linear at all. Once you take it in the ass to get a whole carat the bump up to 1.25 or so isn’t that bad. So many people want to be able to say they have a carat that they can charge a premium for it
Blue Nile was great to deal with and will clean and tighten the prongs as long as you have the ring. They just opened a store in Bolingbrook I think so you yourself don’t even have to go through the trouble of shipping it insured via fedex. I know
Turk bought his stone from blue Nile and had it set elsewhere because they didn’t offer the setting his wife wanted so that’s an option as well.
Highly recommend insuring it also. I think I pay a little over $120 a year and the deductible isn’t bad at all. Doesn’t matter if it’s lost, stolen or flushed down the toilet they fully replace it at least once before it gets costly to insure.
