Looks good.

Is it eye-clean?
 
Nice Diamond. I reviewed the cert, its a keeper. And I like the way it looks in the photo. This is a very good looking SI-2. The price is right. Are you going to get it?

Nice diamond''s picture!! It might be me, but I think there is a scratch at 6 o''clock in the table.
 
Good Eye!

Thats a feather, according to the plotting diagram it is inside of the diamond.
 
Will it cause any problems? I think the IS image looks good

and is the ones at 7 considered indented natural?
 
From the photo it looks like we are seeing the pavilion inclusion reflecting up to the crown.
 
Never say never. But from the diagram and the photo it looks like it will not cause any problems.
 
The vendor said it is eye -clean and has good light performance.
What should I ask them more?
I am considering the tiffany repleca setting

Which one would be better?
 
Hi, Norman,

What is a "cert", and what is a "keeper"?
 
Compare to this one, which one is better?

http://www.jamesallen.com/diamonds/F-SI2-Ideal-Cut-Round-Diamond-1213292.asp

A brilliant stone, F color, inclusion is noticable under loupe but not to naked eye, inclusion could have prong set over it, the cavity will not cause problems.

I think this one has a better IS picture, but smaller size. And this one is $300 less.
 
IS picture for the JA one:

the first picture.

Sorry, I can''t upload pictures here.
 
For the setting, I like the Novio inspired one

Hi, Norman,

What is a ''cert'', and what is a ''keeper''?

I believe Norman is referring to the grading report as the cert and a keeper means a diamond that he feels is worth consideration for purchase!
 
Hi Guys:

Thanks Lorelei for converting my text into English! So, what’s the decision on the diamond and the setting?
 
I am still thinking. Now I have 3 choices:

1) http://www.exceldiamonds.com/Loose_Round_Diamond-143/Loose_Round_1.04_Carat_H_Color_SI2_Clarity_diamond-274735.html

2) http://www.exceldiamonds.com/Loose_Round_Diamond-143/Loose_Round_1.03_Carat_H_Color_SI2_Clarity_diamond-353362.html

3) http://www.jamesallen.com/diamonds/F-SI2-Ideal-Cut-Round-Diamond-1213292.asp

Which one is the best?

Depends what you''re looking for in your diamond. #1 and even more #2 will have a slightly different personality from #3.

#1 & 2 have high LGFs... these black arrows are your contrast and your fire hotspots. You''ll be more likely to get a twinkling, sparkly effect than big flashes. #3 will give you those big bold flashes of fire, but it won''t twinkle like the first two.

How much you''ll notice the difference without having them side by side... that''s a different question entirely, but I''d wager that it would be visible to the naked non-expert eye.
 
Thanks, this is a very professional comment. I just want the most beautiful and valuable one in natural light. Forget to say: the 3rd one is about $350 less than the first one.
 
And the size difference between the first and the third is noticeable.
 
I did a little bit research and found this on Whiteflash website:

A very basic example of aesthetic difference would be the difference between an "ideally" proportioned diamond with lower girdle facet lengths under 75% (tuned to perform optimally in low-light conditions), one with lgf lengths greater than 80% (tuned to perform well in direct lighting), or one with balanced lgfs around 77-80%. Each of these diamonds may receive the top, "ideal" cut grade. Each of these diamonds may have a tight range of proven proportions. Each of these diamonds may have an excellent reflector footprint for overall light return but their appearances will be slightly different in different lighting conditions and in the eyes of the beholder.

So how can I know the LGF of a diamond?
 
LGF is lower half number, it is on the proportion profile diagram. What other numbers are there that is in the 75-85% range? :P

I see. Thank you.
According to the reference above, the first diamond is 80% and the third one is 75%. It seems the third will perform better in natural light. Am I right?
 
I think I am focusing on the first and the third one now.

First:

Pros: bigger, also the vendor offer tiffany replica setting in palladium (not too much maintenance as white gold and also less expensive than platinum)

Cons: the cut maybe not as good as the third one (AGS0, ideal polish and symmetry in third one), $350 more, the color is also lower ( H compare to F in the third one)

Now I know the size difference is noticeable and I want to get a 1Ct diamond.
My question is whether the cut and color difference between these two stones are visible to the naked, untrained eye in natural light?
 
Any suggestions?
 
I would say both are pretty similar from the IS image. You have to remember GIA rounds the LGF in 5% interval so the lower half can be much smaller, maybe in the 78% range, probably not higher. Both IS look good to me, so both are good. Color depends on you sensitivity, but mounted and view from top individually one probably should not be able to tell the difference between them. Face up difference is about 0.25mm.

Check that all of these are eyeclean if you haven't already done so - a couple of things that need to be addressed; both the first and last diamonds have cavity inclusions, you need to check with the respective vendors that these are not a potential durability issue. They are all well cut stones so if you can check out these particular points then go from there. Also with the LGF's any differences are going to be very subtle, not something that is an obvious difference between them especially with the untrained eye.
 
Thanks for all of your comments.It seems that No1 has a cut as good as No3, right?
I checked them with the respected vendors and both of these two stones are eye-clean.
I am going to check with exceldiomand to see whether the cavity in No1 would cause potencial problem.

Is the fluorescence in No 1 a potential problem as well?
