0.4 carat D SI2 diamond with images

[Quality77]

Hi everyone!

I recently purchased a 0.4 carat, D, SI2 diamond which is eye clean! It took me a long time to find one like that. To me, the diamond is beautiful, bright and fiery. It is a GIA certified Triple Ex diamond and has crown angle 34.5, pavilion angle 40.6, table 56%, total depth 60.9%, crown height 15%, pavilion depth percentage 42.5%, star length 50% and lower girdle length 80%. I have done some research and it seems that Ideal scope/ASET images are necessary if we are going to accurately gauge the light performance of diamonds. So I took the Ideal scope and H&A images of the diamond in addition to the picture of it under normal room lighting condition. Since I am not a professional and don't have proper equipment, the Ideal scope image is not the best. Believe it or not, taking Ideal scope images while holding the phone and the diamond isn't easy. Here are my questions:

1. Based on the Ideal scope image, there seems to be areas that might be close to leaking light in the table, but they seems to be minor. I feel that it shouldn't impact the visual performance of the diamond since it looks amazing to my eyes. Am I correct to assume that? Is it also true that some slight leakage may improve the contrast?

2. According to the H&A images, the hearts and arrows patterns are decent, but I don't think it qualifies for a true H&A. But if this diamond is placed next to a super ideal with perfect H&A images, is there going to be a noticeable difference? By that, I mean would the difference be enough to justify a 40 to 50% premium? At this point, I am leaning towards keeping the diamond.

It doesnt look like it has enough leakage to be worth finding a new stone (IMO). Plus the H&A are very decent and you wont notice
the difference between this stone and a stone that is designated H&A (again, my opinion). I think it's a nice stone.

The images look fine. My concerns would be whether the inclusions would hurt light performance, such as if there are a lot of clouds. I also would not buy an SI2 with a feather (crack) as the primary inclusion. Other than that, the stone looks good.

Thanks for the reply. The grade setting inclusion is a feather in the table. Initially, I was a bit nervous about getting a diamond like that. However, I can't see the inclusion with my eyes without the loupe even after I know where the feather is located and what it looks like. As a matter of fact, the feather doesn't impact the visual performance at all in my opinion. I have put it next to an E, VVS2 that has a slightly better cut and I can't tell the difference. They both have the same look and luster. If I don't look at them under the loupe, I won't be able to tell which one is which.
Having said that, I have never seen a super ideal diamond with prefect H&A in person. That's why I am wondering if I can tell the difference. Another poster tyty333 believes that I won't be able to tell if both of them are side by side. Can anyone who has both super ideal and ideal cut diamonds share their experiences? I would appreciate it. Thanks!

I have to congratulate you for two things. One for finding that stone. And then actually taking those pictures.

Congratulations on finding that stone! Where did you buy your kit?

Of course I can't say with 100% certainty, but I doubt you'd see a difference with a true H&A stone and the one you have unless you are louping it. Your hearts and arrows are very nice. I also think in your case it has to do with size. 0.4 carats may not be large enough to appreciate fully the H&A with the naked eye.
