H&A vs Ideal and which diamond is better?

[jpgas]

I'm trying to decide on a diamond for an engagement ring. I know both diamonds have good proportions and we're just splitting hair.

But will the H&A diamond on the right be any different than the one on the left with a better Stonealgo cut score? Which do you think will have more sparkle?

I do like the idea of having a diamond with H&A on the cert but does it really matter compared to another ideal diamond?

The stone on the right looks more precisely cut. StoneAlgo and HCA are just cut quality estimators used as rejection tools, not selection tools.

Can you put these on hold and share the video links?

Really the right one, the H&A, is looks more precisely cut? Problem is I can't see the black arrows the black arrows from the top aren't as noticeable and I know the crown is a bit steeper for ideal

Yes, the right one looks better.

Are these CVD or HPHT diamonds?

CVD, why? would that make a difference?

Sorry I'm still new to diamonds, but why is the right one more precisely cut? Is it a problem that I can barely see the black arrows on the H&A diamond? compared to the one on the left

The right one looks slightly grey, but it has a more evenly cut pavilion. You can see this from the black triangles between the base of the arrows in the left one. So I'd say the left one has better material but the right one is slightly better cut.

I don't think it's a problem that the arrows aren't black on the right one. That's mainly due to photography set-up.

I prefer the fatter arrows in the right one, leads to blockier chunkier light play.

Arrows are black because of obstruction by a black object. Arrows are grey because of reflecting a grey object. In real life they will be whatever color is in front of them!

Thanks, also you don't think the 35.4 crown is a problem? I know it's less ideal but i'm hoping it means more fire. I've been getting conflicting responses from here and Reddit, they like the left more because 34.7 seems like safer proportions

Despite the indicators of very slight pavilion twist, I think the left one looks better...the right one has a dull looking center in the video, which may be due to some excessive digging.
Can we help you find some better options to pick from,based on your carat range and budget cap?

There are plenty of diamonds out there, no need to limit yourself to these two.

Thanks. I have other options but I want to pick this exact carat weight because it’s the same numbers as our anniversary. So it’s just a small detail I’d rather have over other slightly better options

My concern is if the steep crown angle will affect the sparkle enough to not be worth it even though it’s a H&A. But if they don’t have a noticeable difference and have good brilliance and fire I’d rather have the H&A just to say I have one. But if the H&A’s angles aren’t complimentary and will affect the sparkle then I’d rather go with the safer choice

Can you buy both and return the worse performer?

Gosh, I always thought we wanted a crown angle 34-35. @Kim N and @Dreamer_D , are you both fans of the steeper angle on the right stone? Does pavilion twist outweigh a steep crown angle? I admit that I'm confused now, too.

Also, I'm sure experts here can find other 1.83ct stones in your budget. Can I ask how much the stones are?

The H&A is about $1600 the other is about $1200.

Yeah I could. I’m tempted to just get both and try ick the better one. The left looks like the safer pick but I’m always going to be curious about the H&A if I never see it for myself

I honestly think jpgas could do better than either of these stones. The left stone's proportions are safer, and the material is better. The right stone has less pavilion twist. If an ASET image for the left stone could be provided, we could see if the pavilion twist has any effect on the light return.

Can you request ASET images for both stones?

You want a crown angle/table size/uppers that work with the pavilion and lowers.
When you get over 35 the pavilion needs to get shallower.
40.6ish actual in the case of 35.4ish
They are also less tolerant of deviations within the averages.
Pavilion wonk or painting digging quickly hurt the performance.

Karl, what do you think of the cut quality on the diamond on the right?

Thanks that's my main concern the steep crown and the pavilion not being shallow enough to compensate. I want a steep crown for more fire. The H&A seems too steep and the other seems like a safer steep with a more complimentary pavilion angle

Sorry, not at my computer tonight to look at images close enough to comment on specifics.

You said other possible picks. Want the PS experts to look at those for pavilion twist and such?

jpgas let me know when you're online...I found the perfect 1.83 for you, but you'll need to move fast once I post it.

I saw this one earlier and was curious about the optics of it, mainly the paddling. Do you think it might be a tad dark in real life viewing?

 

[Kim N]

Two more with potential.

Environmental reflection during photography is my vote, Kim.

Thanks, I'm going through Rarecarat because I'm getting the setting through them. I found this one on their site https://www.brilliance.com/lab-grow...ake-vvs2-clarity-igi-certified-SKU-LG22940594

but is there a reason you like these more than the ones I picked? It seems like you pick smaller 56% tables, but why?
