Thoughts on a 0.7 HCA Diamond with a shallow crown angle?

[harrybauls]

I'm strongly considering a diamond on Blue Nile (i.e. can't see it before buying) that has a sub-1 HCA score. I'm concerned that it won't perform as well as the HCA tool suggests given its sub-1 score and low crown angle.

Here are the details:

60.2% depth
57% table
32.5° crown angle
41° pavilion angle

Light Return: Excellent
Fire: Excellent
Scintillation: Excellent
Spread: Excellent
Total Visual Performance: 0.7 - Excellent (within TIC range)

I'm pretty new at this. My finance and I decided to upsize from a current (Blue Nile) engagement ring that was an HCA 1.3 so I need to make sure that this won't be 1 step forward and 2 back. They have a great return policy, but shipping (and insurance) isn't free and the fiance really wants to wear her ring.

Thoughts?

Cheers.

I really don't like a flat looking crown, so I always look for 34-35 for the crown angle. I personally would not buy that one. There are lots of others!

I agree with diamondseeker -- the crown angle is low, and with a larger table, the top of the diamond will look quite flat in profile and may lack fire. I believe those low-crown diamonds are more prone to chipping, too.
