Need opinions on this princess cut diamond please

[starsandmoon]

I also posted this yesterday on the RockyTalky section but didn''''t get a reply, so I thought maybe someone here could help me.

DF and I are interested in the following princess cut diamond but wanted to make sure it was a "good" diamond.

GIA certified
5.82x 5.53x 3.95 mm
1.06 carats
Depth: 71.4%
Table: 73%
Girdle: Slightly think to thick
Cutlet: None
Polish: VG
Symmetry: Good
VS2, F
No Fluorescence

Are these specs good? Would you consider this diamond a "buy" or no? If not, what would you consider wrong with it?

Thank you so much

Carrie

The one thing I gleaned from all my research into Princess cuts is that you never want to see a table % bigger than the depth %. I''d pass on this one.....

*NOT* true pg ... so keep researching!

Hehehehe. Just being bratty.
Actually, having a table less than depth does not guarantee good crown height. You'd be surprised to see that some stones with tables the same or even a little larger than depth have better crown angles that some with tables less than depth.
That said, when looking at all the stones on the internet, looking for table less than depth is at least SOMETHING to go by and is better than nothing. And you'll probably notice that most of the good stones have a table close to or smaller than the depth...but certainly not all....
You can't tell squat from depth and table alone....
So if you've seen it and like it, maybe get a sarin test to get the crown and pavillion angles. If you've seen it and love it, then there you go! If you haven't seen too many princess stones, I'd pick out a good vendor and work with him. A good vendor is the key to finding a great princess stone! (unless of course, you'd prefer to go insane trying to buy a princess stone by the numbers alone)

p.s. I kind of like very good symmetry in a princess

I stand corrected, and I appreciate the info! My statement came from two sources: one, I read somewhere on this forum or in a tutorial that for a Princess cut the depth % should always be at least equal to or greater than the table %. And two, every Princess I saw on GOG and WF met that criteria! But I''m definitely no expert so it''s good to see someone with some real knowledge weigh in!

have you seen this diamond? princess cuts are a little tricky to buy "blind"

pg- let''s not get carried away LOL (someone with real knowledge- that''s certainly not me)....actually, almost all the princess stones on GOG have tables less than depths, same with superbcerts and I"m sure for brilliantfire princess stone...but when someone only says ''here is the depth and table'' and it''s not half bad, I say give it a try...so it''s no reason to reject a stone that you''ve seen and liked or was recom''d by a trusted vendor! WOuld it be the *first* stone I call in if I was buying blind on the net- probably not!

Hi Stars and moon
I did not see your original thread, but Utah22 asked for advice on a princess cut today and did not get much response, so this is what I posted:

I am only a novice and most of the research I have done has been on the cut of round brilliant diamonds, but my nephew is planning to propose later this year and his GF would like a princess cut diamond, so I have been doing some reading. This is what I have found.

1.  David Atlas has attempted to classify the cut of fancy Diamonds. See:
http://www.gemappraisers.com/
select AGA cut grade charts then scroll to Princess cuts.

2.  As you have already found out, most tutorials recommend going for a table % that is less than the depth. This, however, does not guarantee a good stone, nor does the lack of it guarantee a bad one.

3.  Predicting the exact performance of princess cuts is essentially impossible from the numbers alone, even when you do have a Sarin report. How the numbers combine is critical and there is probably a host of other factors. The numbers are really only useful for weeding out many of the bad performers.

4.  An Idealscope image will give you a good idea of the light return. I would consider this essential before I considered buying a princess cut.

5.  If possible try and compare any possibilities side by side. Our eyes are very good at picking up small differences when we see thing next to each other.

6.  Make your final decision based on how the diamond looks under different lighting conditions and lighting levels. The halogen downlights at jewellers’ stores can make even the worst performers look good.

7.  On a different topic, have you read any of the threads about the fragility of princess cuts? There was one a couple of months ago titled something like “ Princess cuts – the black sheep of diamonds”. Apparently the corners may chip fairly easily and this would be heartbreaking in an engagement ring. Some people have suggested going for a square radiant instead, as with a 4 prong setting the appearance is very similar, without the high risk.

This is only my understanding, but I hope it helps.
