No expert - but wouldn't you be concern with the inclusions on the table?
Pretty much catch the eye straight away

Not really. It's on the table yes, but that image is VERY zoomed in. IRL the entire dimond is like 9mm across. So you'd have to zoom out a lot to be at "real" size. I don't think it will be noticible with the naked eye from a normal viewing distance.

I don't like inclusions on a table. With the med fluor and internal graining... I'd have to see it in person.

Can they get an aset or IS image? I don't see anything super concerning (and I imagine the inclusions won't be noticible at 6-9 inches viewing distance). But just to make sure the graininf isn't an issue I might ask for more info.
I’m waiting for more information.

Rhino has a school of rock video on YouTube that shows effects of internal graining. It is fascinating, and I don’t really get it, but there can be unfortunate effects from IG, possibly even in a high clarity stone.
Yep, there's a fascinating article on graining as well:
https://www.gia.edu/doc/WN06A1.pdf

Of particular interest is Figure 13. As you can see, even in the stone were the graining resulted in a VVS grade, there's still a slight bit of haziness seen in a blackened lightbox. It's quite pronounced in the VS clarity grade based on graining.

Granted, in each of the above examples graining was the grade-setting inclusion. In cases where graining is not the grade-setting inclusion, it may be a non-issue, but it also might cause haziness. You can typically see haziness due to graining in online videos, but not always. As with the other inclusions that may reduce transparency (clouds and twinning wisps) graining needs to be evaluated in person to determine the impact that it's having on the diamond in question.

Great article Thank you so much!

The fact that the internal training is not marked on the diamond plot means it is of no significance.
You have chosen a magnificent diamond and the Med Blue will give it a better color look.
