Table/Depth ?

[LAD]

I know that it is better for the table % to be smalled than the depth%. But what is there is only 1 or 2 percentage points between them? The one in question is a princess with 73.3% depth and the table is 72.0% Is there a certain differeance that is more desireable? Thanks

Hi LAD,

As you have mentioned it is preferable for the table to be smaller than the depth generally in Princess but there can be grey areas so I would say if you have a diamond where the measurements are close, get ASET and or Idealscope images, plus detailed photos of the Princess in question to see how that combo works for that particular diamond.

There is usually the desire to have a smaller table than depth because the crown height has the greater possibility of being higher (but this isn't always true) and there will be less table glare. For fancy shapes like the princess, going by the numbers alone is difficult to determine how well cut it is. It is more helpful to provide an ASET picture or a close up picture of the stone. However, if the stone is an AGS-0 stone, then there is no worry that the princess is a frog.

But still get images anyway in order to evaluate an AGS0 Princess not only for light return but for taste preferences if you are looking at these diamonds.

I am afraid that it is not possible to analyse princess cut diamonds in the same way as round brilliant diamonds on table or depth numbers
Paul Slegers has written a useful article on how analysing depth in princess cut is misleading - see
