Hello
)
I would take one of these options over any of the others. CBI stones are amazing, and wink is an honest guy who will have stones pulled and inspected. Obviously WF is great too, but CBI would be my personal preference.
Are we sure it's not just overly bright backlighting? It seem likes 95% of the time it's not really leakage but overly bright backlighting.

Wide ranging pavilions and twisted lowers to get EX symmetry.
That's fascinating, thank you!!!! And ugh, thats really a shady practice!
Haha I also learned that trick from @Karl_K ! It's been very useful when trying to "read" these images.@Karl_K discussed a trick to determine overly bright back lighting in a different thread. It was simple -- look at the shades of the cutlet as a reference point and then compare to the rest of the image.
I circled that in yellow and then the more severe lighter pink spots I also circled in yellow. See how those are within the same range? To me, those are back lighting issues.
But the blue circled area with the white (not just light pink) is true leakage, and is more severe than any shade difference you see in the cutlet.
You would see the variation in the mains but the number for the lowers where the damage is done might not be that far off, its averaged for a single number and depending on the twist the average may not be glaringly off.
So I'm on my laptop now and did a little searching. For the same money, you have some super ideal options available that won't suffer from the performance issues of the current JA stone and will give you access to considerably better upgrade programs.

55.8 table, 61.7 depth, 34.4 crown, 40.8 pavilion & 77 LGF
Very similar in size and angle proportions to the JA stone, except this one has true H&A faceting so all the images look rather magnificent. Also, look at the video -- can you say sparkle bomb? Winnner winner, chicken dinner!
Love this stone. Added perk is it measures out slightly larger than the JA stone at 8.33 x 8.35, although in fairness that's more for bragging rights as the difference is so minor your eyes probably can't appreciate it.
My only concern is the SI1 clarity. In the magnified video you obviously see some inclusions, but the site says it's eye clean and since WF vets and stocks all these stones in-house then they can easily pull the stone and confirm it's eye clean or not. Assuming so, this is a great bang for the buck as you get are getting true H&A, killer upgrade program, color you want and slightly bigger size for a few hundred bucks difference.

55.7 table, 61.8 depth, 34.7 crown, 40.7 pavilion & 77 LGF
Lovely stone with small table and lots of fire! No leakage whatsoever, as this baby is firing on all cylinders and is a sparkle bomb! Upgrade program is simple -- spend $1 more and get full credit of the original purchase with no other restrictions!
I know weight is just under the 2 carat mark, but look at the dimensions -- 8.04 x 8.08. The JA stone measures 8.25 x 8.24, so we are talking about 0.20mm variance (or about 1/128th of an inch). This is just right at the point that in a SIDE BY SIDE comparison the human eye can detect a minor difference. If not side by side, you'd never know it was different.
You save $1,000 and avoid the 2 carat weight premium cost, plus you get a H&A stone and killer upgrade program. No brainer IMO if the size is acceptable.

56.5 table, 61.1 depth, 34.2 crown, 40.9 pavilion & 77 LGF
Love this stone. Table is slightly larger than the last and here you are getting a shallower crown coupled with a steeper pavilion. As you can see in the images and videos, this is still a magnificent stone performance wise.
However, because of the different angle combinations, you squeeze out a little more spread dimensionally than some of the higher carat weight stones. This one measures out at 8.12 x 8.14! That's only about 0.10mm variance from the larger JA stone, or about 1/256th inch. Some folks won't even be able to see a size difference when side by side.
Another perk here, you get the VS1 clarity. While probably overkill I love it honestly. Again, same upgrade program and a true H&A stone.
It's very hard to notice .1mm in real life. The typical thing we tell people is the .2mm is where the difference begins to be noticeable, but mostly if you have them side by side. Over 2mm it starts being pretty obvious. But I would 100% go with WF over this JA stone, especially if the difference is size is so small. I'd cancel this order if I were you.

Yep its tilted. The longer arrow shafts point in the direction of the tilt.

All are among the best. Everyone has their specific preferences, but overall you could pretty much blindly pick an ACA and be happy (obviously while still paying attention to size, color, etc)
