Does an excellent or ideal cut make a stone look bigger? How about H&A?

    @IheartUFC:  …the cut quality doesn’t make it look bigger, but certain cuts face up bigger than others.

    The cut quality can absolutely both make it bigger and make it look bigger. Some poorly cut diamonds are deeply cut and will face up smaller. Ideal cuts will have a larger diameter than deeply cut stones. The cut quality also enhances the light performance of the diamond which causes more light to be reflected and the diamond to look bigger.

    As far as I know it won’t make it appear larger… Just more glittery!

    It depends.  A poorly cut diamond can be cut in a way that makes it look smaller or bigger, dependign on it it was cut shallow or deep.

    Primarily, a properly cut diamond will look more splarkly, which is pretty delightful.

    Yes it will. Poorly cut stones have leakage around the edges, making it appear smaller. Excellent cut stones will have no light leakage, so the light will be reflecting from all over the stone.

    Poorly cut stones may also be cut too deep, where a 1 ct deep stone’s dimensions will be smaller than a 1 ct ideal stone’s dimensions.

    It can also face up larger, where it’s dimensions are larger if it is shallow. But shallow stones have the most light leakage in the border/edge areas. 

    I had a great picture.. let me try to dig it up.

    PS: I thought you were going to get a moissy?

    This forum isn’t the best for these types of Qs. I constantly see false information being spread here. If you want to do extensive research on this, head to Pricescope. Or go on YouTube and look at GoodOldGold ‘s informational videos.

    But as a very quick comparison, this is a good pic I just found.

    I had another image that compared 3 different stones, ideal, very good, and good. I can’t find it, sorry 🙁 

    But Moissies should always be cut with H&A/ideal pattern. They come in a little tray, like eggs, and there will be some differences. The jeweler I had my family work with (David Klass) hand picked the best one out of the lot for us. I got to look myself, but since it wasn’t for me specifically, I just trusted him to pick the best one.

    This is a good video on that, too. People always think the cut grade of “very good” means that it is very good, when in reality, it’s far from it 😉

    PS– the average jeweler will never push you to put ‘cut’ above other qualities, so I think your jeweler’s pushing you towards a good start. The average B&M jeweler will give you some BS about “quality” being the color and clarity– which is not true. Cut should go first. In fact, if the cut is excellent vs very good, you’ll notice the tint more in the very good than in the excellent. Oh god, that’s bad English… Ex: You have one ideal cut J in front of you, and one very good J in front of you. You will be able to see the tint more obviously in the very good than in the ideal. In the ideal, you’ll be seeing more LIGHT play, not just a glassy flat diamond.. Jeez i’m horrible with explanations!! LOL!

    @madelise:  Great picture, thanks for posting.  I think we all just learned something.

    Ideal hearts and arrows cut.  1.70 center stone.  I’m my sure how it appears next to a cut that is lower.

    @NovaRising:  You’re welcome. It’ irks me beyond belief when false info is spread because I feel like it is wasting readers/believers’ money! :O(


    And to have a bit more conversation about the topic’s title.. 
    Excellent cut and ideal cut are both terminologies used for cut grade. However, the word “ideal cut” is not part of the GIA taxonomy. It’s part of the AGS taxonomy. So GIA excellent can be quite decieving. A stone that is graded as excellent by GIA can range from “pretty damn nice” to “best thing out there”. Whereas AGS clarifies that by calling the “best thing out there” ideal. There’s no such thing as GIA ideal.

    Now that is all talking about light performance.

    H&A is just a flavor of light performance. “Hearts and arrows” is a brand, really, but not all hearts and arrows cut pattern diamonds are part of that brand. And not all diamonds cut with that pattern will have excellent or ideal proportions. Some jewelers will show you the pretty little arrow and heart patterns in a poorly cut stone.

    So you have to be careful with the jewelers you trust. There are some real big scumbags out there!!

    Other flavors of diamonds can also get an ideal grading from AGS: ideal cut princess stones, cushions, vintage-diamond styles like the August Vintage cushions and rounds, etc. They all are extremely well performing, but they are not H&A.
