One other thing...there is extra cost and extra benefit to buying stones from a vendor such as the ones who carry the superideals and other ideal cut stones as opposed to one with virtual inventories. The trade-in and buy back policies usually are vastly superior. People do use them.

There are a lot of things to consider besides who sells the cheapest diamonds.
Back to Envyme.....Another option (which I may have mentioned before and am not sure if you have done so) is to tell Victor that you have X dollars to spend on a diamond, want a very well cut (ideal proportions) GIA Ex stone at H-I VS2, and let him source you a stone. If you do, I think he will give you a discount on the setting. I would at least ask him about this. May as well cover all your bases if you haven't done this already.

DS,
I do know very well that you recommend stones that are not superideal, typically to folks on a smaller budget. Usually when someone comes around with a decent size budget we see the "with a budget like that you can definitely get something very nice" line (not necessarily from you) and they are recommended several superideals.
And it's not that I have an issue with that. It's the exaggeration of how beautiful that diamond will look when compared to another well cut stone (or an exaggeration of how "ugly" the other stone could be). It's the insistence to consumers that you are making a mistake and selling yourself short by not getting the best you can. It's things like this: http://www.whiteflash.com/about-diamonds/diamond-education/beware-of-phony-hearts-and.htm Is that really what you'd expect a "regular ideal cut" diamond to look like? No, but it is a perfect example of how customers are constantly warned (i.e. scared) about the "worst case scenario" without being told that it is an exception and not the norm if you stick towards the centers of GIA excellent and/or AGS ideal and an HCA below 2.
You are absolutely right that there is added value aside from the cut of the stone, but since I had started my questioning about the advantages of perfect h&a, it really wasn't meant to be a discussion about what value lies in a superideal besides the cut. If you want to emphasize the black and white perks to consumers I absolutely agree. They should know about these added benefits and value incentives so they can take them into consideration.
diamondseeker2006|1427857548|3855365 said:Yes, I saw the numbers on the site. I would want an ASET or idealscope image. I prefer images on any diamond. This is not a superideal cut. You need to decide if you want superideal or not. If you don't, then there may be other options. In any event, did they say they'd sell the diamond without the setting?
I asked you a few posts back about her preferences..as in do you think size is the most important spec to her? Do many of her close friends and family have diamonds that are 1.5-2.0 ct+? I am just trying to get a handle on whether the size needs to be as large as possible, or whether a more modest size but higher quality in that halo will please her more.
Envyme|1427859430|3855383 said:I'm so sorry. To clarify the ring is for mebut yes most people we know have a 1 ct or smaller- most smaller but both hubby and I like larger stones typically but not at the sacrifice of cut and clarity. My big thing is jewlery. I'm not into clothing, shoes or handbags. So to me I like larger stones. We used to own a 2.83 OEC in P color but the stone was a bit too warm from the side... at the same time it was a beauty because it was an OEC with beautiful facets. I now feel like size is not as crucial as the other "C"'s. I can't have it all
so somewhere I have to sacrifice something. Inclusions visible is about the most annoying thing to me personally so I would take a .50 ct stone that's a vs2 over a 1 ct Si1 that's not eye clean any day.
I don't want to look like I have a teensy stone either but I think a 1.3-1.4 isn't super small especially with a halo that's ideal or super ideal.
So would the JBG stone be equivalent to the WF Expert Selection vs GOG being equal to ACA from WF?
Also if I want an ASET JBG said I'd need to pay for it but I don't know what the cost is to do that. Waiting to hear back re that.

Both stones are beautiful, I am sure, but I would choose one of them over the other because of better light performance. Others here obviously do not care about getting the better stones within the ideal cut range, and that is fine for them. But for me, I want a stone that is one of the best, even if NOT superideal, when I am spending $10-20-30k!

By better stones do you mean stones with less leakage? And how did you determine one had "better" light performance?
Teobdl,teobdl|1427977112|3855725 said:I'd be very curious to know what criteria allowed the diamond with the poor IS to be an Expert Select. The crown/pav combo puts it on the edge of AGS 0, and that combo often has some leakage under the table. I think I remember that for diamonds with tables and lgf's in that range, a 40.8 pav with greater than 35.5+ gets dicey. The HCA says it's a 3.4, btw.
It's been mentioned before that people with two eyes wouldn't notice that kind of leakage.
Nonetheless, without more definitive info about how nice that specific ES diamond is, I personally would not buy it.
One thing is for sure: if you're buying any diamond, stick with the typical PS proportion parameters + GIA ideal/AGS 0 or 1, and your likelihood of getting leakage is reduced to near 0.
teobdl|1427729675|3854524 said:pfunk--your tenacity for pursuing these questions is appreciated by all, even if it may be a thorn to some at times. Whether some are holding fast to ideas due to obvious vested interests, or whether they truly do believe certain ideas to be the case, is probably impossible to sort out on an online message board.
Earlier you had asked about research that quantifies the differences btw super-ideal vs ideal. It's an interesting question that has yet to be satisfactorily answered, probably because no one actually knows.
Some things to keep you learning if you want:
I don't have time to wade through everything right now, but Peter Yantzer, the executive director of AGS, has a few slides about increasing # of perceptible virtual facets by increasing correct cut precision and by increasing diamond size/weight for a tolk MRB. These slides can be found somewhere in Wink's library of videos, but I can't remember which one (maybe the one on scintillation?):
http://www.screencast.com/users/WinkJones/folders/Educational%20videos/media/d1898713-1545-40c7-a7b7-cc9af775c47f
Paul makes an appearance, and John Pollard might have been there too.
Keep in mind that quantifying the differences in virtual facets is one thing--understanding how these VF's make differences in perceived beauty is quite another, especially when one takes into account distance, lighting, vision acuity, and personal taste.
Finally, Sergey (Serg), Garry Halloway, and others have been collaborating on research for a number of years to 1) understand differences in cut, particularly how the brain interprets these differences and 2) to quantify these differences in a way that correlates to human understanding of diamond beauty wrt contrast, scintillation, and brightness. As you can imagine, these are not easy questions to answer, and the research is ongoing. I think some of that preliminary work can be found here http://www.gemology.ru/cut/english/document4.htm . A primary focus of their present work is one-eye vs two-eye perception.
My current personal opinion on the topic discussed is that the pinnacle of cut precision is generally not worth the extra money unless the buyer understands that it is mostly a "mind clean" purchase in the same way that one might purchase an D-E vs a G color.
