width or length?

[teppy]

How does the length vs the width get measured? I don''t understand on a princess cut diamond how to distinquish the two. Is the length always the largest diameter and the width always the smaller diameter? Or is it vise versa? On my appraisal, it has the width at 6.55mm and the length at 6.25mm. The depth is 4.55mm. If I calculate the ratio using this, it comes out to 95.41. This is using the L divided by W formula that I found on Bluenile. The strange thing is that the appraiser used the smaller diameter of 6.25(the length) to get my depth percentage. Either he marked the length and width measurements in the wrong place on the appraisal and put the length measurement where the width went and marked the width measurement where the length was supposed to go, OR my depth % and table percentages are not correct.

I''m confused about why it matters which dimension is which. It''s all a matter of how you hold it, isn''t it?

It matters because to determine the table %, you use whichever number is specified as being the width.

should I rephrase this question? Is the width usually always the smallest diameter and the length usually always the largest diameter on a princess cut stone?

It appears the longest measurement is always listed first as the width, even in cuts like pears and emeralds where you aren''t typically going to set it like that. I assume it''s an industry standard.

In any fancy-shape, length is longer than width, thus your appraiser mis-stated that.

All percentage-calculations are based upon the smallest diameter, the width.

That is also the reason, why such percentages cannot be compared to those of rounds, where the percentage is calculated from the average diameter.

Hope this helps,
