Need advice on diamond proportions?

[arcangel]

I am looking at a Diamond and wanted to get some advice on the measurement and proportions:
Is the following good proportions?
Radiant

Weight: 1.57
7.01 x 6.50 x 4.20
Depth: 64%
Table: 66%
Girdle: Thick to Very Thick

Also, a thick to very thick girdle, is this not a good proportion?


Thank you,Teri
