It depends on what price you’re hoping for.

Also, I would never buy a “Good” cut diamond. Cut is by far the most important factor in how that diamond is going to look, and “Good” doesn’t mean good at all.

With those specks it will range anywhere from from $889-$2000. 

Blue Nile – you can search by diamond only and purchase them from their website. I know a lot of people have used them and they are reputable.

James Allen is also supposed to be really good. Do get at least an ideal cut as the stone will be much more sparkly and will even show less color than one with a lesser cut.

Good cut does not really mean good. So for sure go with excellent or ideal. I have a very good cut round diamond and the one thing that bothers me about it is the cut and I regret skimping on cut for carat weight. Jamesallen.com  has the best prices I have seen and their customer service is great!

I used James Allen and Blue Nile to get the “average” cost of the stone I wanted for my Fiance. I ended up with a 1.02 carat / E color/ VS2 princess cut.

What I worried most about was dimensions of the stone. Being a princess cut, I wanted to be as square as possible but still have decent specs.

The one I purchased is 5.44 x 5.47 which translate to a 1.005 to 1 ratio!

When it comes to clarity, VS2 is very eye clean, Si1 and Si2 are also. As long as you could avoid clouds and carbon inclusions, you should be looking at a very pretty stone.

I visited 3 jewelers before I found my 4th and purchased from her.

When it came to budget, I went over $300 but I very happy with the purchase.

But from my perspective (a guy), specs mean more to me then it does to my Fiance. I told her all the details and she replied with, “ohh ok? i still love it!” lol

Mslannister:  I’d try Adiamor. My SO and I are getting our rings there. I’d advise you not to get 0.6 but go for 0.59 if possible. You wont notice the difference and you will spend less! Also, I’d never sacrifice the cut! Go down on color and clarity (I know there might be pretty perfect SI1/2), but it’s the cut that makes that rock sparkle! 😉

I dissagree that you need an excelent cut to have a beautiful stone.

There is more to a beautiful stone tham the 4 c’s. I really wanted a firey ideal cut, and they were mostly labled GIA “very good” cut.

By dropping one level on the cut, I was able to increase to E color, and VS2 clarity.

You will definatly get a better deal buying from Blue Nile. I got their credit, and got a year, intrest free to pay.

First of all, what’s your budget? I’ve compared diamond prices before from Blue Nile, James Allen, good old gold, brilliant earth and all those other online stores, and the cheapest that I found was Adiamor, but that’s mostly because they’re not as famous yet, and does not carry any famous designer names when it comes to their ring designs. All their designs are their own, but there’s a bit of a catch, they don’t provide real photos of the diamonds or an ASET, so if that part bothers you, then go with James Allen, good old gold, or even Brian Gavin, Blue Nile also provides some kind of ASET but only with their Ideal cut stones. The diamond I bought from Adiamor was an Emerald cut. I also wanted to see the stone in person anyway, and not just photo, and they have a 30 day return, no questions asked if you don’t like what you got. If you’re going to do a diamond search from these sites, make sure to do an advance search, and not just by the 4cs, make sure to include table percentage, height percentage etc. if you can’t see the actual photo, ASET, or video of the diamond. And yes, cut is very very important, an excellent cut or above will sparkle better than a good cut, and can make your diamond look even bigger. Also, keep in mind that fancy cuts (other shapes except round) will be cheaper compared to a round diamond. Also, are you looking for a modern cut diamond? Vintage diamonds are lovely too!

Also, make sure that your diamond certificate is certified by either GIA or AGS. EGL and other companies are kind of off when it comes to grading diamonds, like if they grade a diamond D, it actually means it’s an F or G. You can always buy an EGL certified diamond, as long as you know what you’re paying for. Most chain store’s diamonds are certified by not so good companies to get a higher grading, which means they could get more money from those who doesn’t know much about diamond grading companies.

Good cut is not good enough. Also you are kinda backwards buying the setting first. You need to know what mm in size stone the setting will hold. 

I would stick to ideal cut stones since CUT is the most important C and the brighter/sparklier the stone – the bigger your stone will look!
