Is this the most brilliant cut?

[lovediamonds4ever]

Can you please comment on the cut of this diamond? Is it the best cut? HCA score is 1.5 and AGA score is 1A. My concern is the crown angle and pavilion angle are at the border line of the heart and arrow cut specifications. The table of 58% is not as ideal? The price is $16912 if pay with wire transfer. Do you think it's a good buy?

Should be a beautiful stone. The table percentage in this case is not as important as the crown/pavilion numbers which do complement each other.

Can you get an idealscope image for the stone?

 

[lovediamonds4ever]

This is the only image they provided. Can you tell what the yellow areas are?

 

[Gypsy]

Diamonds reflect. An F will be blindingly white. Don't worry. I wear an F. Most people think it's a D.

I just received an ideal scope image. They said it's a little dark. Can you comment on its brilliance?

 

[Gypsy]

Idealscope image is what you need for rounds.

It's a strong ASET image, which corresponds with the given proportions.

John that ring of kind of bleached red around the center, what is that?

Nothing to worry about. The photographer is using a backlit ASET environment. This typically results in lighter hues under the table than more standard non-backlit ASET photos, which we see more commonly here. Personally, I'm a fan of backlit ASET. It's a bit harsher - especially with fancies - but that setup reveals windowing better than non-backlit.

OK. That ring is why I wanted the idealscope. THANKS!

No problem. You may find it interesting that Ideal-Scope photos are backlit as a compulsory, but since they are primarily red-black only (white backlight) the photo is far easier to execute. For reasons a pro photographer can explain better than I can; three hues is far more difficult than two.

In gemological terms the ASET view provides more information than Ideal-Scope - particularly when it comes to the half-facets and painting/digging - but when trying to capture a photo it's significantly more difficult to capture a representative ASET image.

I see more green in the areas that would have been red if it had been an ideal/heart to arrow cut. Is this stone just good or very good cut.

I'm not sure I agree. Can you provide examples of backlit ASET images with less green?

In a technical analysis there is slight painting of the upper halves at 1:00, 6:30, 10:00 and 11:30, but the backlit environment makes these more pronounced than non-backlit and their impact on brightness is debatable.

Sidebar: Pursuant to my dialogue with Gypsy, the areas I identified would not be detected in an Ideal-Scope image.

 

[lovediamonds4ever]

Can you confirm this stone looks like a heart to arrow / signature cut? For under 17K, is it a good buy?

You did not provide hearts and arrows images. You provided an ASET and a picture. If you want us to check the hearts and the arrows we need those images.

I meant to ask if you think this diamond has the most brilliance, fire, sparkle that you would buy for an ideal cut? Is it a good buy for the price or are there better cut stones for the same price? I am aiming for the best cut but triple excellent GIA doesn't really tell us that.

The ASET photo shows great brightness and contrast, and the cut-consistency appears strong. From the data given, and supported by that ASET, the diamond is a candidate for AGS 0 light performance as well as being on the high performing side of GIA 3EX.

There are different notions of what "best cut" implies. Some pros would say any diamond with a label of "Excellent" or "Ideal" falls into that category. The most pedantic specialists require far more data and in-person analysis or verification.

In the Pricescope mainstream this diamond satisfies the most popular community checks: A grading report from a top lab. Color and clarity choices that are reliably strong. Good basic numbers, an excellent HCA score and a supporting ASET image. Based on the information provided here the pricing appears very competitive.

Thank you very much John for the response. I wanted to buy a true ideal cut but GIA Excellent doesn't really tell us that and I didn't want to pay premium for signature, hearts and arrows, or AGS0 cut.

You're welcome.

When you say "true ideal" do know we can't be certain of that: AGS has stricter finish standards than EX, requiring good crystal and more time from the polisher (thus a premium) so it may not have Ideal polish & symmetry. In the same sense, achieving a top level of H&A commands extra time/skill, high quality tools and an expense of carat weight (thus a premium).

As for the interpretive: Whether a GIA EX also meets 0 light performance requirements calls for added vetting/analysis by someone educated in both metrics (thus a premium). With your seller providing clear Magnified and ASET images I've done that for you here. No premium from me. Isn't Pricescope cool?

Can you tell what the yellow areas are?

Likely a reflection of something, perhaps the photographer's yellow shirt that was visible to the diamond through a small hole in the light tent or dome.
BTW, the black areas (arrows) are reflections of the camera/lens.
The yellow and the black are not in the diamond any more than the zillions of colors that will appear in the diamond while worn.

Diamond behave like little boxes of mirrors and windows.
This is one thing that makes photographing them so challenging.

Kenny has given you a good answer and I would like to add that at times I get reflections of the light emitting diodes that surround the lens of my small close up video camera. Especially when it they are not turned on, which is most of the time. In your case, I suspect that Kenny is correct that it may be from a shirt or other yellowish item in the surroundings of the photographer.
