Seeking advise on this diamond especially proportion (relatively larger table)

[minhon]

I bought this diamond on JA.com. The diamond look white and bright under light. But as I don't have a lot of samples, I am not able to compare it with many other diamond's cut.

What I worry is the proportion combination- the larger table which slightly bigger than depth, and the lower % of crown height. Other parameters is ok. I chose this diamond due to the relatively clean clarity in the VS range (no dark inclusions).

JA GIA gemologist said there is nothing to worry about....

I checked the HCA scores is 1.9 and is there any expert who could comment on the desirability of this diamond please?

Thank you!!!

People might advise you that the table is bigger than advised, as you know, but I think the angles are good and it's a lovely diamond. If you don't mind the size of the table visually, or the architecture of the crown, I think the patterning is very attractive, and it should have nice light return. It's similar to my diamond, though my table is a bit smaller at 58%.

nice 60/60 style diamond.

I much prefer the proportions of the superideal cuts which would usually have meaurements within the parameters below. I especially prefer smaller tables which allow one to see more of the crown. But of course, you may like the style above just fine.

Table: 54-57 or 58
Depth: 60-62.3
Crown angle: 34-35.0
Pav angle: 40.6-40.9

Its a pretty classic 60/60 with a slightly steep crown. It has a BIG spread at 6.55 mm vs comparable "ideal" that will be about 6.47 mm, you'd need to get to about 1.05 mm for the same spread. The trade-off is that it will return more white light than fire.

If you let us know the cost of this diamond , we can show you a few that are more the "ideal" style and you can compare them side-by-side in the videos and see if you prefer one over the other.

the cost Is 5900 USD. some online consultant said the crown height is too low And said i should never choose a diamond table bigger than depth...but JA expert said this cut it is not uncommon, they usually look at the crown angle rather than the height. And the idealscope shows light return Is good...

Thanks you guys

With a 34 degree crown and ignoring the gia rounding with a 61 table the crown height is 13.2%
With a 33.5 degree crown which is a common and accepted in a 60/60 style stone and a 60% table the crown height is 13.2%
With a 60% table it would be 13.5%
Gia rounding makes it impossible to tell exactly where yours falls but I would not worry about crown height if you like the 60/60 look.

I like the one you found for size/spread, but here are one within the above guidelines.
https://www.jamesallen.com/loose-di...g-color-vs2-clarity-excellent-cut-sku-3516959 (6.52 mm)

If budget allow, this is lovely and has as small table and chubby arrows. This will be more firey. You'll need to request an Idealscope Image (IS) from JA.
https://www.jamesallen.com/loose-di...h-color-vs1-clarity-excellent-cut-sku-3475223 (6.51 mm)

These proportions give you a smaller spread compared to the 60/60, but fire over white light. So, trade-offs.

Thnaks for your recommendation.

So you don't care the strong blue problem? Worth to switch from None to strong blue for better fire?

And do most PSers don't care the clarity problem given it is eye clean. Even dark inclusions?

Thanks!!

Take a ruler and measure the size of the diamond you see on your screen. Then, remember, the actual size is less than 7 mm. So, you are seeing this bigger and way more magnified. Scoll the magnificiation down halfway and it looks very different.

Many PS member like and seek out flourescence. Just ask the JA gemologist (not sales associated) to ensure it does not make the stone milky (which is rare and usually at "very strong"). Its a very cool. It can also make a lower color diamond look whiter when in natural light or other UV sources.

IT is a rare person with exceptional visiion who will be able to see the little dot on the VS2. It is really the size of a dust spec that is only visible under 10x magnification. So, that size dot at a VS2 or VS1 is not an issue for me. If clarity is at all a worry, stick with the VS1. PS member's range in clarity tolerance, some like VS2 and above --others will accept SI1/2 that are eye-clean to achieve greater size or color.

The VS2 you posted, has "additional clouds" that may be fine, but make sure to ask the JA Gemologist to review it before they send it to you (think of a cloud like a drop of milk in water). The VS2 I posted has twinning whisps and pinpoints, which are less problemmatic, but should be checked and we still want an IS on that diamond. The VS1 I posted has nothing to check relative to clarity adn the IS is good.
