Can't decide based on 4Cs alone, any GIA cert number to refer to?

GIA: 6211625016
HCA:
[attachmentid=8434876]

ANA:
[attachmentid=8434877]

Enchanted Cut Score:
[attachmentid=8434878]

GIA: 1172933516
HCA:
[attachmentid=8434879]

ANA:
[attachmentid=8434880]

Enchanted Cut Score:
[attachmentid=8434881]

If only 2 to choose from, then GIA 1172933516 (diamond 2) is a better choice. However, if it is up to me, I won't buy neither one because the HCA score is too low to my liking. Standard advice is to filter out anything that goes above the score of 2. I also won't go for SI2 diamonds, just personal preference.

For around RM 5700, you can get this:

AGS-104090534005
HCA:
[attachmentid=8434889]

ANA:
[attachmentid=8434890]

Enchanted Cut Score:
N/A (only available for GIA cert)

Minor complains I have for this diamond is probably the star length of 56%. The hearts and arrows look great to me, although I won't rate it really the best of the best.

Or maybe from BGD:

AGS-104090535018
HCA:
[attachmentid=8434908]

ANA:
[attachmentid=8434909]

Enchanted Cut Score:
N/A (only available for GIA cert)

Note: AGS is comparable to GIA, if not better.

One more advice: Always get the diamond images - Actual diamond image, ASET image, IdealScope image, Hearts & Arrows image.

Hope this helps and good luck!
