Can anyone help me take a look at this please?

Gia7151582337 round brilliance 2.5 F si2. I am very interested in this stone. Is it a good one?

Thank you so much.

A grading report communicates some information, but there are always unknowns:

Knowns
> High color
> Nice spread for weight.
> Primary measurements are good for brightness (GIA EX, predicted AGS 1)
> While potentially very bright, fire will be limited

Unknowns
> Can't tell if the SI2 is eye-clean, if it matters to you.
> Once in a while GIA SI1-2 with abundant clouds have reduced optics (probably ok, but verify)
> The feathers set the SI2 grade, are there implications? (probably ok, but verify)
> Many data points average 8-16 measurements apc, then round them, so we cannot know the level of cut-consistency.
> 3D optical precision also influences performance particulars, if it matters to you.
> VG symmetry grade may (or may not) be an indication of lesser consistency/precision (need to see)
> Personally I'd want to see the crown-natural too, but that's being picky

An Ideal-Scope or ASET image would allow further conclusions about performance potential. As it relates to clarity - in terms of durability, eye-visibility and influence on optics - only someone with the diamond in-hand can come to meaningful conclusions.

Nice to see you around John!

Great post as always but I was wondering if you could elaborate further on the VG symmetry. I have read and believed that the differences in EX and VG (when graded by GIA or AGS) symmetry would be extremely difficult for the natural eye to discern. Evidently this may not be the case and it would be interesting to hear more.

Hi Christina, and thanks.

You're right: The human eye cannot distinguish between EX-VG Symmetry, which largely has to do with meet points and alignment.

As an 'unknown' I am noting that a VG grade in SYM could imply an assembly-line process where less attention was given to the fine-details of top make. Cutters who focus on high consistency and optical precision often achieve the top SYM grade as a by-product of the process. In the same way, one might expect the finest steakhouses to get the highest marks in health-code compliance.

Maybe no issue at all. But a note I'd include on my own checklist to investigate.

Ah! Yes, that makes complete sense. Thank you!

Thanks for providing this explanation, John! I have often wondered about this very thing... and it totally makes sense.

Thank you all for your valuable response.

I have attached three pictures of the diamond and hope it will give more info to all those experts here.

I believe the feather can be covered partly with a prong and I am planning to set it in a cushio halo. I have looked at the diamond in person and it looks pretty nice. The only concern is the feather near the edge.

I am almost pulling the trigger for this diamond, but before doing that I sincerely ask for your valuable comments!

Millions thanks

Dear all,

I was told that the above si2 is a good si2 quality coz the major inclusion is the feather near the girdle which can be covered partly by the prong. However I did some research on the Internet on feather and durability of the stone, I start to wonder if such inclusion is really a good one or a potential threat? My husband is a little skeptical about si2 clarity and he prefers si1. But this stone presents to me to be a pretty good si2.

Please help me decide!

 

[Poshjo]

Please please help me decide! I don't have any reliable person to give unbiased opinion, different dealers that I have have conflict of interests.

Thank you so much

In general, feathers are not an issue. And if/when they are; it's the reason you have an insurance policy. Even a flawless diamond can take a knock the wrong way and chip. Just be sure to insure your jewelry properly, whether as a rider to your homeowner's policy, or with a jewelry-specific insurer.

I suspect the reason no one has replied is because the images you posted don't communicate anything about light-return quality. The H&A viewer image (top) with the blue filament paper indicates that the optical precision is somewhat average to above-average in the crown. There is some predictable darkness under the table in these images due to table-reflection, but that's a normal dynamic for the depth of the pavilion and table size. Not a deal-breaker, but something to be aware-of.

Table reflection is most perceivable when the diamond is under diffused light or illuminated from the side. That could be light from a table lamp, reflected from the walls or coming from the horizon, for instance.



Quite frankly, you are in the best position to determine whether the diamond speaks to you in terms of attractiveness and appeal, and is a match for your expectations and your budget.

Dear John, thanks so much for your replies. I went to see the diamond again today and I like it a lot and so I finally bought it.

Thank you again for your help!
