With the shallow crown angle and the steep pavilion angle I would be worried about it's light performance. Can you get an Idealscope or ASET image for the stone? Personally I feel a 32.5 degree crown angle is just too shallow and a 41.6 degree pavilion angle is way too steep. You will also have a flat topped diamond. Here's a recent post about the rounding GIA does.

Here are some parameters that can help you vet stones:

Table: 55-58%
Depth: 60-62.3 degrees
Crown Angle: 34-35 degrees
Pavilion Angle: 40.6 to 41 degrees
 
Pass - it scores a 4.0 on the HCA (good only if price is your main criterion). Ideally you want a number under 2, then get an idealscope image. This one may have the carat weight you want, but it is not well cut, will not sparkle, will show more body color and not look as white, and will possibly look smaller than it should for it's weight because the cut is inferior. You can do much better.

Is this a GIA stone?
 
Yes, this is a GIA stone.
 
Do you have to buy through the jeweller? Or could you buy the stone somewhere else and they will set it? Is the setting done, or are they waiting for the final specs of the stone?
 
Nothing is finalized.
 
Whats your budget? If you are open to buying online, you can have the jeweller set the stone of your choice into the setting. If it was being custom made and had to fit into certain specs it would be more difficult, but still doable.
 
I'd rather not buy online.

Here's the catch, my future father in law (assuming she says yes) is best friends with the jeweler. They have a great reputation in my area.
 
See if he can pick some stones with the specs I gave you. Having a diamond with said specs will be much more likely to give you the sparkly, fiery, brilliant look you're after.
 
Yeah, if you have to buy from him, give him the cheat sheet and tell him to pick stones that fall into that critera.
 
Does he only deal with GIA stones? You could ask him to look for AGS 000 - that would narrow things significantly - they've already been proven to have ideal light performance via ASET - no guesswork as with GIA (whose "excellent" cut category is too broad, and a lot of duds slip through - like this one).
 
What is your budget for the stone? Maybe we can find some stones for your jeweler to call in.
 
Hey everyone!

So, I've drafted up an email to go to the ring designer and jeweler. I don't want to offend him or his team.

Do you think this would be appropriate to send off to them?

Hello,

I shared the GIA number with another jeweler for a second opinion. They had a few observations that honestly all sound Greek to me. I was hoping you or Frank could provide some additional feedback on their observations seen below. Please keep in mind, I'm simply trying to get the best diamond I can and learn about these factors at the same time.

- 32.5 crown angle is way too shallow and 41.6 pavilion is way too deep (worried about light performance)
- the ideal combination is far away from what this diamond has
- scores a 4.0 on the HCA. Ideally you want a number under 2

They recommended staying within these parameters:

Table: 55-58%
Depth: 60-62.3 degrees
Crown Angle: 34-35 degrees
Pavilion Angle: 40.6 to 41 degrees

Can you also please provide an idealscope or AGS scope?

Thank you very much!

Hi there! I think it's good to be sensitive to him and his team. Here's some feedback for you.

I may not say you went to another jeweler for a 2nd opinion b/c it sort of sounds like you don't trust his expertise. Which after coming on PS, maybe you don't :)), but you don't want to offend him and then have him not want to work with your wishes.

Asking for feedback on the parameters could be setting you up for them to tell you not to worry about those things. He may say, "Don't worry about the 32.5 degree CA, it's fine!"

Most jewelers don't know what the HCA is and if he doesn't, he probably won't put a lot of stock in it. Same goes with the Idealscope and ASET (not AGS scope btw).

So, maybe something like this:

"I really want to get the best diamond I can for "name of GF." Since the ring is such a big investment, I've been doing my due diligence and I've been learning a lot about the importance of the cut of the diamond and how the cut is what gives the stone the sparkle, brilliance and fire. I'd like to buy an Ideal cut diamond within the following parameters. Can you help me vet diamonds that fall into that category?"

"Also, I learned about a couple of tools to assess light performance. They are an Idealscope and an ASET. Wondering if an Idealscope or ASET image can be provided for diamonds I'm considering?"

Oh and you can ask him if he can get AGS stones. IF he can, then ask for AGS 000 diamonds and you'll be all set for the parameters and light performance. No need to get IS or ASET for an AGS 000 diamond!

I would just plug the new numbers into the HCA yourself when he provides you with diamonds that fall into the ideal parameters.

The above is a suggestion, so please tweak (or ignore) so you feel comfortable.

I was hoping you or Frank could provide some additional feedback on their observations seen below. Please keep in mind, I'm simply trying to get the best diamond I can and learn about these factors at the same time. I am not sure you want to mention another jeweler. Instead, I would say that you have been doing a bunch of research and have learned that there are more ideal cut combinations that could provide better light performance and ideally you would like to stick to the parameters noted below if possible.

- 32.5 crown angle is way too shallow and 41.6 pavilion is way too deep (worried about light performance)
- the ideal combination is far away from what this diamond has
- scores a 4.0 on the HCA. Ideally you want a number under 2 I am guessing your local jeweler has never heard of HCA, so you might want to stay away from this. I think the recommended parameters below should be helpful and you can always do the HCA on a stone before the jeweler brings it in.

They recommended staying within these parameters:

Table: 55-58%
Depth: 60-62.3 degrees
Crown Angle: 34-35 degrees
Pavilion Angle: 40.6 to 41 degrees

Can you also please provide an idealscope or AGS scope? I think you mean ASET not AGS. AGS is a like GIA (a cert) and your jeweler could get an AGS Ideal certed stone. That would be a safe route for you, because AGS Ideals have already been evaluated for light performance, so I would ask them if they have any AGS Ideal cut stones to show you.

Thank you very much!

It sounds like you are kind of stuck with this jeweler, so you obviously have to be careful to not offend them!! My thoughts are bolded above. I hope it goes well for you!
 
JDDN has given you some good advice/pointers. Her note sounds very "friendly".
 
Thank you everyone. I do trust this jeweler, and I think all of your points will serve me well.

Glad i posted before shooting off this email :)
Thank you!
 
Good luck and let us know how it goes!
