Will greatly appreciate input from all the experts and advanced amateurs on the forum on the two diamonds listed below. I am considering them for a pair of Pt studs.
I have the Ideal scope and hearts images. Vendor didn’t have ASET scope images for the diamonds. There is a small difference in sizes between the two diamonds, will that be a problem? Will these have good light performance? Anything else I should think about?

A
1.51ct G VS2
Measurements 7.31 x 7.37 x 4.55
Depth 61.9%
Table 56%
Crown Angle 35.2°
Crown Height 15.5%
Pavilion Angle 40.7°
Pavilion Depth 43%
Girdle Thickness 3.4%
Cutlet Pointed
Fluorescence None
Cut Ideal
Polish Excellent
Symmetry Excellent


B
1.44ct F VS2
Measurements 7.24 x 7.29 x 4.45
Depth 61.4%
Table 57%
Crown Angle 34.7°
Crown Height 14.5%
Pavilion Angle 40.8°
Pavilion Depth 43%
Girdle Thickness 3.9%
Cutlet Pointed
Fluorescence None
Cut Ideal
Polish Excellent
Symmetry Excellent

Proportion wise both are promising. The idealscope of stone A has leakage. That is the whitish/light pink ring you see. It’s not horrible by any stretch but if I’m just being honest I’d want none if paying a premium for a TH.

Have you looked at WF yet? They have H&A stones and normally competitive with the TH collection, sometimes less money. And IMO, the cut quality is tighter.

In regards to size, the proportions can make a stone tall & skinny or fat & wide. Here the differences aren’t major but rather than judge carat weight, look at the spread instead. In this case, about 0.007mm difference. Not detectable to the naked eye.
 
I would go with B because I see leakage in A
 
I would go with options C and D:



These are a part of the flagship ACA lineup at WF, the company that @sledge mentioned

I don't disagree, but there is a difference between F/G and I color, so just worth considering.

Thanks Deja for taking the time to find ACA diamonds for me. Really Appreciate your help.

Thanks Sledge! I will look at WF and am sure they will have something that will exceed my expectations for studs. What is TH collection?

sorry, my reading comprehension is terrible today. As this is for studs, I woulnd't worry about I color at all. And TH collection = James Allen "True Hearts" line.

Yes, true. Figured they'd face up with as much white light as possible since they are going in platinum studs.
Without knowing a budget, I took a shot in the dark...
 
@sbc86 I forgot to add this to my previous reply...

Here are the platinum studs that WF offers, in case you do go with ACA diamonds and want them to make you the whole package (if they have a style/set that you like):

Thanks Deja! You are extremely helpful.
 
Thanks @lovedogs. Yes, TH = True Hearts, which is JA's version of a H&A stone.

@sbc86 I'm assuming you have these two stones on-hold @ JA? I searched but couldn't find them. Standard GIA 3X stone are running $12-15k. Assume the TH's are at the top end of that price range for each. That said, here are a couple of ACA's that I think would work lovely for you, keep you in the same money and not make you sacrifice size, color or clarity.


Look at the proportions, nearly identical. Despite some carat weight difference, the spread dimensions are nearly the same as well. Total cost for both is $26,696 wire. My only concern is the F-SI1 has a CLEAR crystal on the table. Pretty sure it's a non-issue as WF states it's eye clean, but I would have them pull the stone and confirm.

@DejaWiz both the ACA and TH stones will have good edge to edge light performance. Granted stone A above has some minor issues. But my point is that well cut stones reflect light properly extending edge to edge and making them look more bright (white) and sometimes even larger (as dark edges "shrink" a poorly cut stone -- see video below, one of my faves to illustrate this point). While there may be minor differences between the ACA and TH stones, I wouldn't expect enough to think an ACA I color would outperform a TH F/G in this regards.

Now if @sbc86 wants to save a few bucks and go with a lower color, I'm all for that. It just depends on their sensitivity and tolerance for tint.

 
@DejaWiz and @sledge you were both very astute in selecting the sizes of the diamonds for the studs. Sledge your top range estimate is very close. I would prefer to be able to get the diamonds within $35k. My current studs are 6.5mm. I read that to see any difference in size you have to go up by 20-30%, so I arrived at 7.12mm - 7.27mm range for the new studs. You gave me good ideas and I am certainly going to look at Whiteflash ACA and see what works for me. Diamond A is no more in the running.

Reason for looking at FG/VS diamonds is that my engagement ring is E/IF and it is set in Pt. I know it is an overkill but that is what my husband selected with the help of his parents. I want to take the time to find the best diamonds. I do not anticipate getting another pair of studs after this one.

How do these look to you?

 
Thanks Deja! They look amazing.

You're very welcome!
They tend to go quick, especially after being posted here at PS, so put a hold on them ASAP if they are your frontrunners.
