Ah, you spoiled my fun with an edit, I was going to correct my uber educated friend on her typo
Sorry HVVS but I think you might have made one of the same misleading statements that RD often makes. You compare two diamonds that have 5 things different between them and draw a conclusion comparing only one or two of those differences saying that that particular characteristic like lack of optical symmetry contributes to an overall appearance.Date: 4/6/2010 8:33:27 PM

JustEngaged, Brian Gavin of Brian Gavin Diamonds recuts diamonds. You can contact him through his website. There are at least two or three threads here about diamonds that Pricescope people had recut. Sometimes the stone loses minimal carat weight and diameter. As a worst case, say you can't exchange that diamond, or trade it in on an upgrade, and can't stand it the way it is. Then, possibly it could be recut. He can recut it to hearts & arrows, or just tweak it a bit here and there to improve the performance. It would lose some weight, but you have already spent the money to buy it, you'd certainly lose a great deal trying to sell it yourself, and a recut would cost less than $1000, most likely, and maybe more like $700 to $800.
Most people can't tell the difference between a 2ct or a 1.7ct, and whether the diameter is 7.8mm or 8.1mm. Certainly not if the diamond is on your moving hand.
So, all is not lost.
One thing that I would definitely do before I panicked about the cut is go to a jeweler that sells Hearts on Fire or unbranded hearts and arrows or other 'ideal' GIA and AGS excellent cuts, put yours beside some of those, and see whether there's any real difference, or which look you prefer. Or whether these 'improvements' that are called ideal are even worth the extra cost. I have a H I-1 diamond that is not even graded by any lab. I bought it from a pawn shop, actually. It has some almost-arrows, and I'm not sure about hearts, and the arrows are not extremely precise and kind of broad. They are rather like big black spokes at times. I also have a Good Old Gold superideal H&A. It pegs the charts on all of those testers that GOG has. When I put those two diamonds side by side, that non-ideal H I-1 throws big 'blade' flashes, like sword blades, of brilliance and fire, and the H&A looks more refined with it's more slivery flashes. But both are very attractive diamonds. If the H&A diamond is a 100% on performance, the uncerted diamond is still at least 96% and is actually more attention-getting than the H&A in certain lighting. Plus it tosses lots of brilliance back in office lighting, and people think it's an E or F color because it faces up so blindingly white.
So, in that respect, David 'RockDiamond' is correct. Ideal or beautiful depends on the observer, as well as the cut. Some people prefer Old Mine Cuts, or Old European cuts. And some of those are far from 'ideal.' So, if you are happy with the look that your diamond has, that is what matters.
BTW, I sent a diamond to BGD to be evaluated for a recut, because it was mostly dull in the center and that bothered me after a while. Brian will look at it and tell me how much weight & diameter it might lose.

I think you both have valid points but are aiming for two different conclusions. HVVS is saying it does not matter *why* one diamond looks better or *why* they look the same, all that matters is that to her eye, the diamonds look close enough that it was not worth paying the premium for a perfect cut stone in that case. I think a lot of consumers would draw this conclusion if they looked at stones in person. The nuances of what make a "super ideal" appealing are sometimes subtle and not everyone is going to appreciate it when they think about the cost.
* R(diamond) = TAN(41. * 50 = 44.71%
Nope, can''t recall that far back in my education. Strangely, that formula doesn''t come up much in my daily lifeDate: 4/7/2010 3:15:54 PM

Stone, this is a little harsh
I also do not know the equations and I am a PhD
Come on, simple assumption using volume of cone formulation,
1/3 pi r * r * h.
Surely you know that much?
and where would that increase in volume/weight go to, into a blackhole? think a bit and not ask others to do the thinking for you.
They will be on the GIA paper, listed near the same place that the color and clarity grade is listed.
