Looks awesome
I doubt anyone but the most experienced trade professionals would be able to tell the difference in real life between a 34.5 degree crown angle and a 35 degree crown angle, everything else being equal
@diamondseeker2006 would you say that the ASET has to be perfect? What if an ASET cannot be obtained? Is viewing the stone itself good enough?... I see you have commented that the stone looks fine in OP's photo... so is that enough? While as much data as we can collect is, of course, most advantageous, what if one only has the actual stone to view? Is that enough? Does that play into the GIA position that one needs to go by what they see (and how they feel about it), versus all the technical data? Thank you for you input!
35/40.8 can be a trainwreck because the actual average angle can be closer to 40.9 which means that some angles can be as high as 41.1. Combine that with high crown angle or 35 (which is also rounded) and potentially twisted pavilion, you have leakage.
But in OP case, this is not a concern. It is well cut.
How do you assess 35/40.8 without the ASET?
A well taken magnified photo or video is enough. In person, you can build a ASET for yourself or cup your fingers or hands to use it as idealscope. It works well.
Your stone is beautiful and very close to my numbers as well. Sometimes you have to step back from info overload, data and decide for yourself, is this my stone? Do I love it enough to wear it proudly every day because you will look down at it very often and hopefully it’s to admire the stone’s beauty.

Would not this "averaging of angles" apply to 34.5/40.8 angels as well to the point that they might be considered a "trainwreck"? Or is there a less of a chance of that happening?
It is because of 34.5 CA which can handle slightly steeper PA. There are 34.5/40.8 that are trainwreck as well. There are 35.5/40.8 that are stunning but the odds are lower. It is just probability. If leakage is your main concern, choose a shallow combo such as 34/40.6, but now your start to concern about potential obstruction issue.
No leakage at all. No worry in this regard.Got it! Would you say, based on the IS image I have posted, that this particular diamond has a light leakage?

Since you really want to assess your diamond and want it to be perfect, the diamond has dug out girdle.

I personally would feel totally fine if I found a stone within the range we normally recommend and can see at least a photo of it before ordering. I might order a 34.5/40.8 without a photo, but it still would make me uneasy buying anything I can't at least see a picture of. A magnified face of the stone photo is very helpful, but it is never enough for stones outside the recommended range. Those absolutely have to have an ASET or Idealscope image. Then, if I have either perfect numbers or other combos that result in a 1-low 2 range HCA score, I'd order and see the stone in person. I am not sure I'd even know what to look for if I hadn't already had superideals to compare them to, though. The average person going into a jewelry store with no prior diamond experience is usually going to think very good looks just fine!
So regarding the stone the OP posted, I knew the numbers were good and the stone looks good to me. Now that she has posted the idealscope image,I think it is a very beautiful stone and in the top tier of GIA Excellent for sure!
These are good questions! I was not able to obtain ASET but I do have an Ideal Scope image. However, I have received mixed reviews where some said that it is a good image with a strong light return, the others said that it has a light leakage. I just could not see where exactly. That was the main reason I considered WF over JA and still do (this diamond is from JA). There has been a lot of critique over 35/40.8 angles on PS, thus the doubts.
This is a great idealscope image! I wish people wouldn't comment on images when they don't know what they are talking about! It's better than the IS on the stone I had with similar proportions, and mine was totally fine, too. I think you chose very well! If this is a forever stone, I think it's fine. The reason to switch to a vendor like WF would be if there was a thought of every upgrading. However, if you could keep this stone for a pendant and get another diamond in the future, I'd certainly vote for that!

So then this IS a good Idealscope image?

With all the twisted pavilion stones on the market today I question buying any stone online without images.I might order a 34.5/40.8 without a photo, but it still would make me uneasy buying anything I can't at least see a picture of.
