Is it a milky diamond? Worth investing?

Hi can anyone comment on this stone? The seller says its not milky (no BGM), but it looks less transparent when compared to other similar grade diamonds?

Spec: D/VVS2/3Ex/non, video here

can you post the GIA report (by the way if that is supposed to be a modern round brilliant cut stone the table is huge).

That's from their analysis, no idea why the GIA just show 59%, if I knew it's 63.2% would not have bought that in first place. How does the video of the diamond look?

I would go with GIA’s grading. Who is the other info from?

From the seller, they do internal reports for our reference. Now I am more considering whether I should return the ring as I am not sure whether that's a milky stone. Can anyone tell?
 
Why do you question the stone being “milky”? That term is often used when a stone is of top color (as your is) with too much fluorescence… but your stone has none.
Have you always thought the diamond has the appearance you are concerned about?
Have you had the diamond cleaned? I think you need to start there.
There are no inclusions that would create a problem as this diamond is of very high clarity.
What concerns me is why a seller would assess a diamond to be anything but what the grading report from the world’s foremost authority on diamonds says it is!
Are you certain the diamond you have matches the report?

not sure the terminology, whether that is called milky or hazy or the word that describe it does not have fluorescence but is not crystal clear when not affected by inclusions. I cleaned it with home use ultrasound machine. It could just be unclean but I cannot tell.

The GIA report matches, not sure theirs, and from the GIA report I cannot really tell why it looks less transparent, I know it would be less sparkling, thats why posting here want to gather some expert opinion of whether I should keep it or not.
 
The fact you are questioning it tells you your answer: return it.
Honestly, even if people here told you it’s fine you will always see what you are seeing and will forever question the choice to purchase it and be upset you didn’t return it.
I strongly recommend you return it as you are not happy. You shouldn’t be questioning it so this is not the diamond for you. We can tell you it’s great, as example, but bottom line is it isn’t an attractive diamond to you so you shouldn’t get that one.
With all this said, I’m assuming you can still return it???

Don't think it can be returned for free if the diamond has no problem. Unless the saleperson has misrepresentation - that's why want to check here if the stone actually got problems.
 
Well, its not a well-cut stone to start with and it does look a little odd in the videos but it may just be the photo setup. Do you have the
stone in person? Are you seeing that it looks odd with your own eyes or are you just going off the video? If you do not have it
and can stop it from being sent...I would stop it.

Look for a better-cut stone.
 
Those with more expertise please chime in, but I don't think that GIA report is for the diamond in the video. The report does not show the inclusions in the middle of the table, or the dark crystal in the center of the bezel.

Calling @Karl_K , @Kim N and @DejaWiz
 
It's an issue of light leakage due to the extremely steep pavilion angle causing a dull and boring center.

The video may be a mismatch, but the face-up scan image matches what I would expect visually.
The "predicted light performance" ratings are completely false and exaggerated, in my opinion.

Here are some examples of diamonds with the same pavilion/crown/table combo, and the "ring of death" leakage is highly apparent.

This isn't a well cut stone
 
The stone in the video definitely looks milky. But the stone on the GIA report has no major red flags that would suggest potential milkiness, other than the comment about surface graining. This could be a mismatch or the stone had some sort of film on it when the video was taken.

The table measurement in the vendor supplied report does not match the GIA report. The stone in the video has a table that more closely agrees with the GIA report. (look up "bowing method" of visually estimating table size.

I would be concerned until the diamond can be inspected by a qualified professional, verified against the GIA report, and determined not to be hazy.
 
No matter which set of numbers or images is right its not a well cut stone.
I would start over if at all possible.
 
Thanks all it’s really helpful. I can’t tell if that is the right report/ video. Did not realise the Crystal either on the center bezel. This is the video that I took with another D/VVS2/3EX/non in a jewellery store. I can just tell it is less transparent.

Afterall it’s is 3EX, not sure why it can still be that milky/hazy…

3X is pretty broad so it doesn't guarantee great optical performance...and it has nothing to do with the overall material quality that the diamond was cut and polished from.
There are plenty of grainy or cloudy 3X diamonds that would meet 3X, but have severely inhibited light return and optical performance.
Unfortunately, 3X being broad enough in regards to pavilion/crown/table combinations that aren't anywhere near ideal means that many of those combinations will lack the proper reflection of light resulting in noticeably reduced beauty.
About 70% of diamonds graded by GIA get assigned "3X", if that is any indication of just how broad and rather undiscerning it is.
 
This was the video that I was viewing before I bought it and the diamond was looking fine and non-milky, what is the reason?

The stone on the video is milky. Milkiness significantly reduce Brilliancy, crispy.
so Diamond Optical performance is worse than predicted by just 3D model
 
As Serg and others have mentioned the stone is milky.
Also as Bryan mentioned the BS report does not match the stone in the video and the GIA report.
GIA can give diamonds that are hazy as a result of internal graining even flawless status. Almost always when there is surface graining there is internal graining.

There is something wrong with GIA's methods that miss internal graining. It may be because they are more reliant on the IBM GIA AI clarity system, or simply the backlighting if anyone at GIA is still looks at diamonds with a microscope?

I stand corrected...I thought it was solely the poor cut proportions that was causing the issues with the optics and appearance.
 
Thanks all, the store has now referred a gemologist (which I shall assume have no conflict of interest...?) and we are planning to do a stone check. After all the comments, we are also suspecting that this diamond is not the same one on GIA cert - there should be no way to cheat? Will be checking the GIA inscription on the girdle and the stone condition.

All that is the sellers problem just move on and if you have paid anything demand a refund.
 
yup so the seller has referred a gemologist for us to check, and said if there is anything wrong with the diamond they can do a full refund. But the seller is so confident that there would be nothing wrong with the diamond.

From a cut precision and proportions standpoint alone, there is quite a bit wrong with the diamond. With this diamond, you're merely buying diamond material weight, not buying a high degree of diamond beauty.
 
There is a lot wrong. Please just get a refund and move on
 
Agree with others to get a refund and move on. Plenty of better options.
