Using the numbers you gave, it scored a 5.4 on the HCA. If this is being sold as "Ideal" you will want to check with the seller on why/how they''re using that terminology. That HCA score said this: "Total Visual Performance 5.4 - Good - Only if price is your main criterion."

Have you seen the diamond? If so, did you see it in natural light or just store lighting? Many people here have found some nice stones at good prices that made them very happy. Unfortunately, without being able to see it in person, we mainly have to rely on the numbers. If you''ve seen it and you''re happy with the look and price, then you can answer your own question.

Here''s a DC on this stone.

Without lower girdle/star info it''s impossible to give the *exact* assessment however this combination of angles, I would not consider to be ideal.

You have excessive leakage under the table and lack of contrast.

For another perspective ... GIA's cut calculater disagrees with my assessment and rates the stone as "excellent" !?!?!? (but this is assuming 80% lower girdles nad 55% stars which I would still disagree with an "ideal" rating for). Oy vey... if this confuses you dedicated then you MUST SEE what this looks like next to an AGS Ideal hand selected stone for a real comparison.

LOL... I can see how the trade (and cutting factories) are going to LOVE the new GIA system.

Wow... just when you''d think it was going to get easier on us consumers, out comes this. Go figure!

OK, now I''m confused. I thought that the numbers posted fit the description of what was supposed to be "ideal". Where did I go wrong? How could the numbers be ideal and the HCA grade it at 5.4? On the GIA report there is an inscription that states "H&A" what do you make of that?!
Some education here would be appreciated.

Hopefully you can get some expert clarification beyond what I can tell you. Ideal is a loosely used term throughout the diamond industry. GIA doesn''t (through current at least) grade cut for the purposes of any report that you would get as a consumer, so unfortunately you''re left to what the seller of the diamond tells you. While this comes as a 5.4 on the HCA, if you look at the actual graph (I uploaded the screenshot), you can see that it''s relatively closely plotted to the AGS 0 box. That being said, as it was pointed out, GIA''s cut tool tends to look at this differently. Since that is a relatively new thing for everyone to play around with, it will probably be a little while until the nuances are learned. I highly recommend getting a look at this stone, and also taking a look at the cost of it versus another ideal that is similar.

As for the H&A, any jeweler can engrave H&A onto the girdle. That being said, giving it the benefit of the doubt (an H&A viewer could confirm for sure), I''m assuming that it is Hearts & Arrows. Hearts & Arrows should not be confused with ideal cuts, but rather excellent symmetry. I wonder if the seller is confusing all H&A''s for ideal cuts. Unfortunately, while H&A can be awesome, it doesn''t mean that it always is, nor does it mean that a non-H&A can''t be fantastic. Take a look here to get an overview on H&A''s http://diamonds.pricescope.com/hna.asp

I really wish you the best of luck. I know the feeling of finding something that costs so much for so little and hoping it can be absolutely perfect. With all the work you''re doing, I''m sure you''ll end up with what you want in the end!
