Need Help Comparing 2 Diamonds - Thanks!!!

[kylejohnson]

Thanks for any insight you can provide. I'm leaning towards the "D", which has a 0.6 HCA score, but I'm concerned about the "Medium Blue" fluorescence and the "Clarity Characteristics". These are both from Blue Nile, so unfortunately I don't have any photos.

Oh, and is a lower table % better than a higher table %? I've read conflicting reports. Thanks again.

 

[kylejohnson]

Any thoughts or opinions?

What lab graded them? Both look nice; smaller table sometimes associated with more fire (colored light return). No need to be leery of med blue fluor (personally I love it - the stronger the better!)

Thanks for your help! They are both graded by the GIA. That's good to know about the fluorescence, I think I was mostly concerned about that.
