Crown Angle too steep @ 36.4 with 40.9 pavilion angle?

[KC-BBQ]

Okay diamond experts. Considering this diamond. Please provide thoughts on if the crown angle is too steep given the other metrics provided below. What possible issues should I be aware of. I attached the HCA below also.

The answer to the topic question is yes.

Is it worth the 12k aking price?

Any issues with setting a steeper crown angle diamond in a cushion halo ring?

Pass on this stone.

The entire purpose of faceting a diamond is to reflect light.
How well or how poorly a diamond does this determines how beautiful it is.
How well a diamond performs is determined by the angles and cutting. This is why we say cut is king.
No other factor: not color, not clarity has as much of an impact on the appearance of a diamond as its cut. An ideal H will out white a poorly cut F. And GIA Ex is not enough.
So how to we ensure that we have the right angles and cutting to get the light performance we want?

Well one method is to start with a GIA Ex, and then apply the HCA to it. YOU DO NOT USE HCA for AGS0 stones.
https://www.pricescope.com/wiki/diamonds/holloway-cut-advisor
The HCA is a rejection tool. Not a selection tool. It uses 4 data points to make a rudimentary call on how the diamond may perform.
If the diamond passes then you know that you are in the right zone in terms of angles for light performance. Under 2 is a pass. Under 2.5-2.1 is a maybe. Over 2.5 is a no. No score under 2 is better than any other.
Is that enough? Not really.
So what you need is a way to check actual light performance of your actual stone.
That's what an idealscope image does. https://www.pricescope.com/wiki/diamonds/firescope-idealscope
It shows you how and wear your diamond is reflecting light, how well it is going at it, and where you are losing light return. That is why you won't see us recommending Blue Nile, as they do not provide idealscope images for their diamonds. James Allen and WF do.

The Idealscope is the 'selection tool'. Not the HCA.
So yes, with a GIA stone you need the idealscope images. Or you can buy an idealscope yourself and take it in to the jeweler you are working with to check the stones yourself. Or if you have a good return policy (full refund minimum 7 days) then you can buy the idealscope, buy the stone, and do it at home.

Did the lab report have an ASET on it? If you post the AGS number, or a link to the report, perhaps?

 

[MissGotRocks]

As you can see from your HCA attachment, this stone does not fall within the white outline which would indicate AGS candidates.

Are you sure it is an AGS graded stone?
