Sorry....I should have compared something a bit more relevant in terms of price I''m looking at. AGS0 3.07ct 9.29 x 9.29 or the 3.57ct pear.

Thanks

a 13mm stone is going to look bigger than anything other than another 13mm stone.

So, a square stone which measure 7.7 from point to point will look bigger than anything which measures less than 7.7 in diameter, for instance a 6.5 mm round stone of 1Ct?

I have seen stones of each of these proportions and the 7.7x7.7 princess dwarfs the 6.5mm round.

Diagem... only if the diamond was mounted or viewd <> like a kite. A princess diamond viewed as a square as with an diagonal measurement of 7.7 will probably look smaller than a 6.5 round. I know that my asscher is about 6x 6 when viewed square... and when measured on the diagonal it is larger than 6 x 6 and mine doesn''t have corners like a princess. It looks much larger when compared to a round if it''s viewed as a kite.

Ok, now I thnk I see where you are. You mean the hypotenus of the right triangle formed by the corners of a square princess cut. Been a long time since high school math for me!

Anyhow, to get a 7.7 hypotenus ( diagonal center line measurement) you need side measurements of about 5.5mm. Yes, that would look smaller, I think, than a 6.5mm round.

Paul, what belle said was meant for the rounded shapes i believe which was the case of op question and she tried to make it simple within the matter.
Your princess will look larger than a trillion with smaller sides than "point-to point" it does not make belle wrong in this particular case.

I think Paul was having fun with geometry. A 7.70 mm square, tip to tip, appears smaller that a 6.50 round because it is, in fact, a smaller stone in terms of what you see on the grading report (5.50 mm is right Beacon
).

some time ago i made a pic for an asscher IRL- hand shot for one poster and never used it, so here you go. I believe the bigger asscher would give bigger visual difference.

Measurements are........?

Our example is using a 5.5mm square (resulting in a 7.7 hypotenus) compared to a 6.5 round. The round is bigger in carats and looks bigger in size.

In the OPs question, I think the pear looks longer and that could be seen as ''bigger''.

I believe original question was more about visual perception than actual measurements. Brain has it''s own ways interpreting optical information, let me dig out that picture with the rails.

Now for the opposite... a 5.50x550 mm. round will visually appear smaller than a 5.50x5.50mm square...
