princess cut advice

[robadamati]

I''m considering the following stone:

Princess cut, GIA CERT
Square Modified Brilliant
6.98x 7.00x 5.10
2.02 ct
H, VS2
Polish and Symmetry both excellent
faint fluorescence
Table% 64%
Depth 72.9%
girdle slightly thick - thick
no culet

Also, can someone explain the significance of the table and depth percentages? Are they good for this stone? someone suggested to me that the table may be slightly small, and while I was in love with this stone originally now I am slightly self-conscious that perhaps the table is too small. Out of everything, this is the area (table and depth percentages) that I understand least.

Thanks!

It is hard to judge fancy shapes by numbers, they really need evaluating in person or with photos and other cut aids, so as you have seen it and love it that is the main thing! The diamond looks fine on paper, the table is not an issue and is in good range, what is important is whole picture of the diamond, how all the components and proportions work together. If you have compared this diamond with others and love it, then it is definitely worth consideration.

Here is a chart you can use to compare your proportions which you may find helpful, but use as a guide only if you look for others, numbers don't always tell the whole story.

Ditto Lorelei - she is spot on when she says that numbers alone cannot be used to judge cut quality for princess cut diamonds.

You may also like to consider AGS graded princess cut diamonds. AGS is the first and is still only lab to grade the cut quality of princess cut diamonds (based not on proportions but onl light performance).

Dear Lorelei:

Thank you for the advice, most helpful. I wish I had seen that chart before asking ... seems the table size on the stone I selected is actually ideal. Little did I know

! Thanks again!

This stone looks like it has potential. For a princess cut, I look for a stone that has a table less than its depth (in general less than 70ish), and a depth somewhere in the 75ish range. These are "ish" numbers because as everyone mentioned, you can''t judge fancy shapes by the numbers like you can for rounds. But in general, a table that''s too large is more of a problem than a table that''s too small. See if the vendor has an ASET scope and can give you a picture through that.
