Can i get feedback on this stone

Looks fine, provided you are OK with the look of a 60/60 stone (less fire, more white light return). It is a bit oddly shaped since it is wider than it is deep. VVS1 and E color are overkill IMO.
 
Even in 60/60 stones I am wary of ones that are wider than they are deep. Have you seen this style of stone in person? And is there a reason for the high color/clarity?
 
We want high color because it will be set on a platinum, halo settings. I understand clarity isn't as important on a brilliant cut, however, it's an Asian thing that VVS1 or VVS2 are desirable, if not required. At the end of the day, I want my finance to be happy with the diamond/ring. However, its tough because local jeweler dont' seem to have these stones in stock...
 
How important is it to you and your fiancee that the stone be well-cut i.e. shine, sparkle and scintillate? Seems like you are prioritizing color and clarity over cut and cut is usually the characteristic that you can see the most as it affects color and how large a diamond appears.

Many people can't tell the difference between colors unless they are several grades apart and usually at VS2 or VS1 you can't see any inclusions unless you are using a 30x loupe.
 
RE: color, unless your GF is extremely color sensitive, you'll be totally fine going down to F/G in color. Most melee for a halo is F/G, so you won't see any difference IMHO.

The 1st priority is cut, hence, the stone i'm looking at is graded triple excellent, what else besides that should I be looking for then?

I was asking about the 61% table and graining comments as I'm not familiar with those...

Not all GIA EX/EX/EX stones are well cut. These specs should get you close to an ideal cut grade:

54-57 table
60-62.4 depth
34-35 crown
40.6-40.9 pavilion
75-80 LGF
 
Table bigger than depth is not the best. Try using this criteria to filter selections:
  • Table 54-57
  • Crown 34-35
  • Pavilion 40.6-40.9
  • Depth 60-62.5
 
I see that the stone i was looking at has table of 61%, crown angle of 33 and Pavilion angle of 41.2. Which are outside of the ideal ranges.

However, a little more research and I found the GIA and AGSL round brilliant cuts proportion charts. Based on table of 61, crown angle of 33 and pavilion of 41.2, it's an excellent cut for GIA and Ideal cut for AGS, I'm using those charts correctly?

Hi Audis410,

You are using the charts correctly. Technically, a stone with these proportions falls into AGS Ideal or GIA XXX range.

GIA XXX range is quite wide. E.g., acceptable table % for an Excellent cut ranges from 52% to 62%. But a diamond with a 52% table will look very different from a diamond with a 62% table.

The closer you are to the middle of the range (not just for table %, I am only using it as an example), the more balanced look the diamond will have in terms of fire, brilliance and scintillation. A stone like the one above, where both table % and depth % are close to 60%, will show a lot of brightness but will lack in fire and contrast compared to a diamond with e.g. 56% table, 61% depth, 34.5 crown angle and 40.8 pavilion angle.

Most of people on this forum prefer a more balanced look with lots of fire, which is the reason for suggesting to stay within the above proportion ranges.

There are also many of those who like the 60/60 look, and especially in higher color grades a diamond like this will look icy white, which IMO can also be really beautiful. But it's the matter of personal taste.

You asked about the 61% table, and the answer is that you cannot look at only one parameter in isolation. It is the combination of proportions that determines a diamond's relationship with light. The proportions in the diamond in question don't work very well together. The performance would have been much better with e.g. a table of 60% and pavilion angle of 41.

You can use this simple tool to check if a diamond's angles are complimentary:

Graining is an indication of irregularities in the crystal structure. It usually appears as a straight or irregular line(s), transparent or white, that can either be inside (internal graining) or on the outside (surface graining) of the diamond. I have a SI1 diamond with surface graining that it nearly impossible to detect. At VVS1, you have absolutely nothing to worry about.

If you are happy with a GIA XXX certificate, I would still suggest you use the HCA tool as it will help you eliminate diamonds where the combination of proportions results in poorer light performance. If you want to dig a little deeper, this is an excellent read on the nuances of Cut:

Good luck!
 
Thanks for the explanation Katya! Basically were looking for a stone ~7.5mm, GIA XXX, G or better, VVS2 or better, max budget is 18k for the stone. How does this one from james allen look?

I ran the HCA tool and came back with a 1.4. Thanks in advance!
 
Or this stone ($1500 less than the above):
Color = G
Clarity = VVS1
Cut = GIA XXX
Measurements = 7.69 - 7.67 x 4.72
Fluorescence = Faint
Depth = 61.5%
Table = 56%
Crown Angle = 34.5°
Crown Height = 15.0%
Girdle = Medium to Slightly Thick
Pavilion Angle = 40.6°
Pavilion Depth = 42.5%
Culet = None
L/W Ratio = 1.0
 
If you have 18K for the stone by itself and don't need to go bigger than 7.5mm I would be looking at super-ideals. This one is gorgeous, and I am 98% sure that you won't notice tinting between a G and this H:

This one is another potential contender, but I'd personally want WF to confirm it's eye clean (and from how many inches away), and also maybe give you a comparison pic btw this one and the closest in size/cut G they have:

https://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-3408406.htm

EDIT. I went back and saw above that you strongly prefer VVS clarity, so both of these might be out. I would just strongly suggest considering them, especially since you don't want to pay extra for clarity you can't physically see (vs. ideal cuts that you can see), but that's IMHO of course.
 
We want high color because it will be set on a platinum, halo settings. I understand clarity isn't as important on a brilliant cut, however, it's an Asian thing that VVS1 or VVS2 are desirable, if not required. At the end of the day, I want my finance to be happy with the diamond/ring. However, its tough because local jeweler dont' seem to have these stones in stock...

I advise you to NOT go to a local jewelry store to look at examples. I made the mistake of wanting to view diamonds in a showroom with my GF. The poor quality she saw in person basically made it so that even VVS diamonds became at risk clarity because the diamonds she saw were so dirty and couldn't be cleaned in front of her.

You may want to just consider a Tiffany Soleste Halo. A ring coming from Tiffany should make up for them using a VS1 and lower carat weight. And their cuts will be good/great without you having to explain about Whiteflash, HPD, CBI, or BGD.

I disagree with this assessment. Are rings from Tiffany nice? Sure. But they aren't worth their insane markups, and you can get a much better quality diamond from WF, CBI, BGD.

OP says he’s buying for an Asian girl (VVS+ or bust) ... so yes, Tiffany is that nice.

It’d be like trying to explain why a Nissan GT-R (super-ideal online vendor) is as nice as a Porsche (Tiffany) since both go around the Nürburgring Ring at the same lap time and the Nissan is cheaper.

The explanation could hold water, but it may not be worth the hassle to have the explanation in the first place.

We have plenty of Asians here who don’t necessarily buy Tiffany... because their diamonds aren’t cut great. I’ve seen some on here that were awful and had to be returned because they were poorly cut. (I’m thinking in particular that emerald cut with the darkness of death in the middle),

You are buying a name.

Frankly, I prefer AGS 0 over GIA XXX

GIA xxx is entirely too large of a category and includes some real duds.


BTW, my sweet spot is an F color. I do like higher colors, I confess.

High Performance Diamonds has a see it in your city program, where they will send stones to a jeweler in your area so you can assess in person.
 
And IIRC, she had to exchange it 2 or 3 times before she or a nice one outside of the store lighting.


Do you have a link to this? I’d like to read what happened.

I bought from a non-Tiffany vendor myself... my gf is getting an amazing diamond/setting combo.

But I’m not 100% sure it was worth the hassle of explaining so much nuance instead of just resting on the Tiffany name. Guess I’ll find out soon enough.
 
@Audis410 ,

I may be a bit biased as I own a G/VS with very similar specs as the second G/VVS1 you posted above, and I love love love it. Its not perfectly perfect, but I do (love it). It also has a bigger spread (although it would be good to know the carat weight) and somewhat better symmetry (again, very subtle). Do you have the GIA report number for the second diamond - I am curious to see its LGF (lower girdle facet)? I do feel inclined towards it, though.

@holeydonut , you made me laugh! Porsche over Nissan, always. But, HPD/WF/BG over Tiffany, also always. Go figure :lol:

In a reread, she had to go back 2 or 3 times, but was able to find a good stone in the second ring she chose.

GIA for 2nd diamond is 6302186887, 1.71 carat, LGF = 80%
 
I have to say my asscher is a G and I sometimes see tint, but my High Performance diamond is a G and it’s very white to me. A non super ideal round G to me might be a little risky for tint. I think you are better off with F color vs1 or 2 just my Opinion.
