diamond measurement question

[odeon790]

I purchased a round brilliant diamond that is .903 carats.

I was just wondering about the size - it says it is 6.18-6.19 x3.85mm. From what I read it seems this is on the small side for that carat weight. Is that true, and if so - what does that really mean?

It is an AGS Ideal cut
depth 62.4
table 53.7
crown 34.4
pavilion 40.8

Visualize looking at the end of a pencil.
Now cut the length of the pencil in half.
Even though it now weighs only half as much it still looks the same size when viewing the end of it.

It is the same with diamonds.
Their depth (side view) can vary without changing how big they look in the top view.
Your diamond is a tad on the deep side for its diameter (face up view) but it gets a 1.4 HCA score, which is very very fine.
