Dear all, this is my first time posting on PS.

I am looking for an engagement ring and after reading through pages and pages of thread, I have narrowed my selection to these 2 diamonds from Whiteflash.

Both are ACA diamonds from Whiteflash. However, I do not really understand why the .0812 carat diamond with similar specifications is significantly cheaper than the 0.801 diamond.

My guess is the light performance as I can see a greater area of bluish tinge in the middle when looking at the aset scopes.
It is more obvious on the diamond certificates than on WF website.

I must admit that I am newbie in diamonds. This is my first diamond and any advice would be much appreciated.

Thank you!
 
The seconomy diamond is VS2 F Versus VS1 E of the first diamond that's why it's cheaper.

b/c the .80ct is one color and one clarity grade higher. ;))
 
Thanks guys! How about the light performance of both stones! And which one will you guys go for!??
 
Actually, both of these stones are not my favorite, and I wouldn't consider either to be "SuperIdeal." The E/VS1 has a painted crown, and the F/VS2 is borderline steep/deep and exhibits some green under the table in the ASET image. Don't get me wrong, both are still very nice diamonds. But if I were paying a premium for a SuperIdeal, I would continue looking for a better stone.

However, if you twisted my arm and forced me to choose between these two, I would choose the 0.801 E/VS1. Slight crown painting (around 3-4 degrees) usually doesn't affect a diamond that much. It will give the diamond a bit more brilliance at the expense of scintillation. In fact, some people actually prefer the painted crown look.
 
@TreeScientist sorry, what is the meaning of a painted crown look? How did you determine that?

@rockysalamander will the SI rating be eye clean? I am quite concerned about the inclusions.
 
If you aren’t sure about an eye clean SI1, you can probably get them to send you the stone first for inspection, and then you can send it back for mounting in the setting.

I have a super ideal SI2 and I can’t see the inclusion. The stone is so brilliant and throws off so much fire and the inclusions are transparent anyway, that I can’t find it.

I do like the idea of gaining size by going for an eye clean SI1
 
Inclusions at SI are very often seen only with a loupe. I have an SI1 stone and clarity-wise it is indistinguishable from my VS2 and VVS1 stones. In many cases clarity is a mind game rather than an actual impediment to light performance - at least in my opinion, and I have good eyes. If you can get over the knowledge that your stone is an SI1, you can have a larger stone that is still superideal. Which do you suppose is more apparent to the casual observer - size or clarity?

As for this diamond,
https://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-4027058.htm I can see the inclusion but I may be able to hide it under a prong?

Anyways, I am from Singapore so I probably can't ask them to send it to me as I will incur overseas charges if I send it back.

Ok gotcha. You can definitely call them or email and ask pointed and specific details about the stone, get them to make a video of it in a holder and on a hand etc.

Also, btw, I do prefer DEF stones (I’m trying to like down to a K, but in my mind, I keep wanting it to be whiter.... I just love the pop of a super bright white stone). My superideal is a G color and it is completely white, no tint.

Have you considered visiting Jan Paul as you are in SGP? Not sure how their price compared with online vendors.

Yes I have visited them and I am also considering some of their diamonds. I think the diamonds are probably just a tad bit more expensive at Jann Paul, but it might be worth it to have a look at the actual diamond before buying.

I'm sure it is a beautiful stone, it did make the ACA brand. For my super ideal mind clean preference there is too much green under the table on the ASET image.

I noticed that too was wondering if any experts here would like to shed some light on the issue. :lol:
 
If it made the ACA grade, I would trust it to be a top performer. If it's in your budget and the specs you want (which it seems to be), I would put it on hold asap while you decide. I wouldn't worry about nitpicking the images too much--WF is really careful about what gets the ACA grade-- but if you are concerned you could ask WF to take a pic of both stones that you are considering together (e.g. on someone's hand) so you can see both and made the most informed choice.
 
For those interested in the topic of 'painting and digging' we have recently posted a new article that hopefully will lend a bit more intuitive understanding of the subject. We are currently working on a video for this page that should be of additional value in helping folks to wrap their heads around this concept.

Also, on the issue/non-issue of green in ASET under the table, you can check out this page dealing with this common question:

Bryan, thanks for responding to this thread. Great articles and I'm looking forward to seeing the video once it is completed.

I understand the center of the ASET can be green, red, or mixed depending on the pavilion angles. I want to make my initial post more clear in that I was referring to the green lower light intensity zones between the arrows most notably at the 1:00 and 3:00 positions. Are these zones attributed to the variations in the pavilion angle?

Was wondering the same thing (:

OK, I see what you are referring to. These appear to be secondary reflections of the pavilion mains.
I notice that crown and pavilion angles are both pushing up against our proportion guidelines (34-35 and 40.6-40.9 respectively). This could possibly result in any variances in pavilion angles right at the red/green boundary to be revealed in these secondary reflections.
The ASET is within our very tight tolerances for A CUT ABOVE and the ray tracing from AGSL did not have even minor deductions in any of the light performance metrics. I will run a VPA on the stone later today to look at the variances in angles and azimuths.
Thanks for the question @crbl999 . It is an interesting observation. :read:
 
VPA does show a bit more variability in the pavilion angles than most ACA's. Enough to make a subtle difference in ASET but not enough to result in a deduction in the AGS ray tracer, nor enough to disqualify for A CUT ABOVE. Certainly not be enough to result in any real life performance deficits.

When looking at VPA reports, it is important to recognize that some variance in angles and/or azimuth is almost always present, even in the top superideal brands. Another caveat is this report is generated from a 3D scan we did at Whiteflash, not the official scan done at the lab.

As interesting as this may be from an academic standpoint, in shopping for a diamond (even a super ideal cuts), differences in the other C's are more meaningful than technical differences at this level of cut precision.

Thanks everyone for your kind inputs! I have decided to move ahead and purchase this stone! (: have a great weekend ahead guys:D
 
@Texas Leaguer Thanks for running that scan and posting the results. I certainly enjoyed learning more about diamonds and love to 'geek out' on the technical aspects.

@ZacharyLee Glad you got the answers you needed to pull the trigger on this beautiful stone.
