Thoughts on these options?

Any input on these 3 options, overall and in regards to light performance? I feel they all look decent in the video's and their HCA scores weren't bad either. Any advice would be much appreciated!

Option 1

Option 3

1.41 Carat D-SI1 Excellent Cut Round DiamondIMO, this would be the best out of the 3. Get an idealscope image from JA.

Yes...and thank you! Can I ask your reasoning? Is it because of the light performance map? I believe I was filtering out AGS diamonds on JA by accident so I never even saw this one.

Here's a little help for narrowing down well cut GIA excellent stones:

table: 54-58

depth: 60-62.3

crown angle: 34-35.0

pavilion angle: 40.6-41.0

Although the AGS stone posted is better than the ones in your original post, I would not recommend it. It is quite deep and I would also want an idealscope image to be sure there isn't leakage due to that crown angle. It just a 2.7 on the HCA, and it is best to have measurements that score at or below 2.0. Plus, in all areas it got a score of very good instead of excellent for the first three and very good for spread which we usually see on the better stones.
