bump. any HELP?

After determining the HCA score is under 2, the next step is to get Idealsope pics.

The Crown and Pavilion angles you input into the HCA are each the average of 8 angles around the diamond.
If all 8 were identical it would be good.

But if some were high and some were low (even though they average out to a good average) that's bad.
An Idealscope pic would reveal this wonkiness.

I wouldnt be able to obtain any other images. They are from Blue Nile and they don't offer ASET's, unfortunately. Im sticking with them because I did get approved for credit.

Without ASET or Idealscope images, it is impossible to tell you which stone is better. Both score under 2 on the HCA, which warrant further investigation - but you have no more methods of investigation through BN. All you can do is buy one, have a look, and hope it is nice.

A completely separate issue is the idea of buying diamonds on credit. You'll find that no one here recommends that avenue.
