Looking for second opinion on lab diamond

[johnsmith2212]

Calling for assistance from diamond experts here. I recently got hold of a lab diamond and the jeweller claimed that it's a Super Ideal cut. The HCA is 2.4 and symmetry seems a bit off for Super Ideal, so I wanted to double-check with the experts here.

I agree about the symmetry; I would not call this a super ideal cut. The ASET and Ideal-Scope have overly bright backlight, but it looks like it may have some leakage under the table.

This one has similar specs but significantly better symmetry.

Welcome to PriceScope, johnsmith2212!
Agreed...this diamond suggested by Kim N has much better proportions and angles.

 

[Karl_K]

Actually it doesn't, both pass the combo can work test and the first stone passes the IS and ASET test but there is no proof of h&a so its not super-ideal.
IS/ASET images trump numbers and there is no harmful leakage shown in either image.
The second diamond im not seeing an ASET or IS image but the proportions are good.

So just wanted to check the IS and ASET image for the diamond passes the Super Ideal requirements, just that there is a final H&A confirmation before it can be considered Super Ideal?

For the H&A, I should look out for symmetry in the H&A? If there is symmetry then it's considered Super Ideal?

Karl, I was using the center of the diamond as a basis, and the under-table areas looked lighter than the center. Is that not the way to evaluate overly bright backlit images?

I would recommend that you ask the jeweler for better ASET and Ideal-Scope images with proper backlighting. Or at least better ASET.

In terms of proper backlighting, you are referring to a whiter/pure black background?

The intensity of the backlighting...it's far too high in the images that you were provided.

This was my thoughts as well. ASET and IS images are great! According to David A., H & A is marketing tactic. I.e. they can charge a higher price. On the HCA grading scale site Garry states anything lower than a 2.4 can have H & A.

Garry says to use a white screen on your phone, but that is too bright. I put white paper over it but it did not help lower the brightness.

 

[ariel144]

Here is a screen shot of one of Jon's older videos of the IS image of one of their best performing MRB. I've looked at a lot of IS images of ideal performing diamonds including the pictures on Garry's website. Under the table it is similar.

 

[Karl_K]

Karl, I was using the center of the diamond as a basis, and the under-table areas looked lighter than the center. Is that not the way to evaluate overly bright backlit images?

The first evaluation is, is it red?
If its whiteish then you move on to the backlight test.
If you blow it up far enough you will see areas in the center that are the same color as the table or lighter.
The biggest issue with the image is it was not cropped and the focus and exposure are way off.
Its a camera issue.
The backlight is within a range that can work.
This is even more so with the IS image, the camera did not focus.

This one has a way over bright backlight.
In that case you would use the lightest area in the center circle as your reference for leakage.

For the H&A, I should look out for symmetry in the H&A? If there is symmetry then it's considered Super Ideal?

Super ideal is made up of several things which have to be documented and shown to you to properly get the label.
Known good proportion set or a border one that had passes IS/ASET tests. (this one is border, it depends on what is in the averages of the numbers and the minor facets).
Passing ASET/IS images.
Hearts and Arrow symmetry images that pass the test.
Properly taken IS/ASET images can be used for the arrow view.
H&A is mainly the hearts view as more things have to be right for it to show properly.
Without the hearts image it can not be called h&a.

Thanks, Karl. Do you mean that these areas (enclosed in blue) are not leakage even though they are lighter than the center?

They are nice and red so the lighter than test would not be applicable. There for there is not any harmful leakage shown.

 

[Karl_K]

Here is what is going on, as you can see there is very minor leakage just a few% that is in the normal range.
The table however is not showing the same.
Its just the way this combo presents.

Got it, much appreciated, Karl!
