If you could at least get a photo or video it would be great... in person is the best. I would recommend selecting the one that is more sparkly to your eyes.
On paper. I am not liking the second one because all of those inclusions (hence the SI2). However, beware of the "I" color of the first one... some people may not like the warmth of an "I" but color of the diamond to me is not that important... the CUT is because that is what makes it sparkle! I have a "J" stone and it doesn't bother me.
I love the fact that they both have strong blue fluo tho!
