Besides the wonderful HCA score of 1.2 it got all four Excellents.
That's unusual.
Usually the spread is only Very Good.

Step 2 now is to see the Idealscope pic, aka IS.
I'd don't know whether that vendor provides them but i'd ask.

Compare the IS image to this chart.



Frankly with Excellent Symmetry I doubt the 8 crown and Pavilions could vary much, so in this case I'd be comfortable buying it without the IS pic.
(The two angles on the GIA report are an average of the 8 angles around the diamond.)

here are the pics I immediately notice that the arrows are a little off.. but how much will this affect performance?

The stone looks really good. The photos you posted are from a hearts and arrows viewer, they aren't an idealscope image that Kenny mentioned. Physical symmetry and optical symmetry are different, this stone isn't a HA ( which isn't important to many people), but it looks like a nice diamond that will perform very well.

I think Stone is Excellent and I am sure all would recommend you, I think you should go for it.

this stone is inscribed h&a on the girdle.. but from what I see it obviously isn't a true h&a.. but my goal is to get a very nice stone with great performance (not necessarily a true h&a) for a good price. these are alternatives that im looking at from a different vendor with a much nicer IMO setup and display of jewels.. but I would have to exchange size for cut.. I think they are all really good stones, just looking for more educated opinions.. I would prefer the bigger stone if performance would otherwise be pretty much the same.

here are the other ones I was looking at

Hmm, can you get an IS from B2C? If not I still think that I would take a chance for the additional size and see what what your eyes think of it in person.

I agree it looks like it could have possibilities. The reason is gets the EX in spread is probably because it's a 60/60 type stone (table and depth are both around or at 60). I think they tend to be bright stones, trading some of the spectral light return for brightness, but please someone correct me if I am wrong. The 60/60 stones I think are probably "spreadier" for their weight as well, which is your other upside on it.

Christina can you explain how physical symmetry and optical symmetry are different? Sorry for the minor thread jack but trying to learn

Sure! Symmetry as graded by GIA refers to the facet meet points, off center table or culet, out of round girdle and such, this is physical symmetry. In order to have perfect optical symmetry all 57 facets are cut to specific measurements and angles and combined with perfectly shaped and aligned facets to create the hearts and arrows phenomena. Many well cut stones display hearts and arrows when viewed through a HA viewer, but in order to be considered a 'true' HA stone the arrows must align perfectly with no breaks, and the hearts must be all the same size with little or no clefts (there is a formula to determine how much cleft is acceptable but I can't remember it at the moment). This perfect optical symmetry is important to some people and less so to others. According to this tutorial https://www.pricescope.com/wiki/diamonds/hearts-and-arrows-diamonds there is no proof that the absence of a HA pattern implies inferior performance, it really comes down to a particular stones proportions and how well they all work together. I'm sure I'm leaving out lots of important info, but I just woke up , so forgive me, but that's basically the differences.

Maybe you could request B2C to provide you Ideal Scope Images or ASET Image, they might be able to provide you, it will help you decide.
