The ASET doesn't even show its a good light return diamond. It has big green areas on the side and even on the table. If you didn't know, green = weak light return = low brightness
Even one of the arrows is off and much smaller = poorer fire.
I found your diamonds hearts and arrows scope
If you do more research, this is not a true hearts and arrows or even an Ideal hearts and arrows. I don't even think you can legitimately call this a hearts and arrows diamond. The HCA won't even work on this diamond because one of its condition is that the diamond has to be symmetrical. This doesn't even pass the basic criteria for the HCA to work.
For you to even compare this with a Super ideal quality is very skewed. It's not even half the quality of a Super ideal cut. That is why, people are saying that its not cheap.
What's most disturbing to me is that this seller is selling these type of diamonds as ''exceptional and excellent light return'' when its clearly not. And I don't know why you're trying to sell this to others. I don't know if you're conned victim or the conman.
