Hi everyone,

I've been doing a lot of research and have narrowed my search down to 4 diamonds. My main priority is light performance and second is carat size.

I'm not sure if I'm reading the ASET images correctly. Is it important that there be as much contrast as light in the diamond or does there only need to be some contrast?

Please let me know what you all think between the below. Thank you so much!!

Is there too much contrast here and not enough light?

I also cross-checked from both vendors and did not come up with any options that were better. ;)2

I'm not surprised; AGS0 Princess Cuts aren't easy to find...esp eye clean, without garbage inclusions against the table, or directly beneath the table. I think the above super-ideal is quite the find!!
 
Thank you so much for looking and sharing your opinions. I'm a girl that really appreciates understanding how someone came to their conclusions. Can you share why you like that one the best?? Is it much better than the others?

I'll tell you why I* like it best.

1. It's AGS0 certified as ACA Super-Ideal.
2. It's extremely eye clean for VS2 clarity.
3. Princess Cuts are not easy to find without a lot of crushed ice & mushiness.
4. Price is right & size is greatest.
 
That is spectacular!
 
For me, they are all similar looking at the IS and ASET.

1.390 I SI1 BGD (6x5.95 mm) and 1.314 I VS2 (5.82x5.8 mm) both had dark inclusion under the table, the 1.390 was more distinct that the VS2 which likely could be forgiven. If these were your only options (or the biggest or best cut for a price), maybe it would be worth considering. But, you had other options that lacked these inclusions.

1.283 ct I VS2 Expert Selection (5.85x5.82) was also really nice. But, compared to 1.51 I VS2 ACA (6.23x6.19 mm) it was a bit less crisp with a hint of less definition between the major cross. Again, given different requirements or budget, this would be worth considering. But, given that I know ACA is a tighter grading standard and it was the biggest with no inclusions...that was my choice...plus everying @Matthews1127 said.

Yes. ^-----this....plus, everything I said. :mrgreen2:
 
Wow, thank you everyone for your help!! I am beyond grateful for all your thoughtful consideration. I'm taking everything in but I also had one question that I hope you all could help me with.

I was initially leaning toward the 1.39 because of cost and light performance. However, I am looking at the Whiteflash 1.5 and trying to justify the $1k more. Yes, it's bigger in size, but what do you think about the light peformance/ASETs between the 2? I think if it was also a better light performer, it would justify the higher price tag to me.

I don't understand why in general the Brian Gavin diamonds I have been looking at have so much more symmetrical contrast than the Whiteflash diamonds. Whiteflash's ASET has more red which makes me think it would be better but it lacks much more symmetrical contrast, and I dont know how important that is. What do you all think between those 2 ASETs and the significance of that symmetrical contrast?

Symmetry is essential for a well cut stone (in your case, a super-ideal). If you're paying $1k more for better cut, and better clarity for a heavier stone, it very well may be worth it. Remember: size is different than weight. Focus on the diameter squared in mm across the stone (l x w ratio dimensions) to determine finger coverage. If you have an ACA, Super-Ideal AGS0 certified diamond, it just doesn't get any better than that for Cut. The clarity sealed the deal for me; Cut has nothing to do with clarity, and it's a whole separate category of concern. The VS2 clarity on the 1.5ct is magnificently eye clean!! If your spread in mm's across is the max you can get out of the above, it's well worth the $1k more!!

I thought whiteflash aca was on par with brian gavins signature...is that not true? ACA is superior?

Whiteflash's ACA and BG's signature are even, and on par. AGS0 Super-Ideal is superior to GIA XXX. AGS0 Super-Ideal is even superior to AGS0 Ideal. A Princess AGS0 Super-Ideal is even more difficult to find, especially one so consistently faceted across the top, and under the table. There is no mushiness between broad facets & smaller facets; everything is evenly distributed. The 1.5ct is an absolutely gorgeous diamond.
 
Thank you so much for your responses! The company was nice enough to provide me a video of the diamonds I was interested in in different lighting. I'm down to 2 choices. The first one is the 1.5 from above.
https://www.whiteflash.com/loose-diamonds/princess-cut-loose-diamond-3599778.htm

The second one is also about a 1.5 ct I color, but it is an SI1 which I don't mind if it's eye clean. It looked comparable in the videos, is supposedly a higher I color, has a larger face up size, and is $1k cheaper.

This second diamond is a surprise to me. It's an ACA but doesn't fit the description of a normal ideal diamond: smaller crown, larger table, table > depth. To me, the idealscope seems to have a fair amount of light leakage too. However, it does look comparable in the videos and it's cheaper, whiter, and face up bigger.

Would love to hear others thoughts! Thank you!!

I’m Team 1.51IVS2.
 
I'm with @Matthews1127 . I like the 1.51 I VS2.

In this case, the inclusions on the SI1 seems to break up the light return. You see the lower left arrow kinda wink out. In the stand-along video, it is the inclusions along the TopRight/LowerLeft axis. I think the diamond is rotated 90 degrees between the standalone and group videos.

Def 1/VS2. Those inclusions in the SI1 are just too much for me, and I'm a fan of SI1 diamonds in general (if eye-clean). The I/VS2 outsparkles the SI1 big time
