can anyone tell anything about proportions from this cert

[hedarud]

I have a center stone that is 1.012 ct and its specs are 6.3 x 6.33 x 4.01, can anything about its proportions be determined by that alone, the original EGL cert is no longer avaiable from EGL USA in LA. Thanks in advance.

That's it I'm afraid hedarud, apart from saying it's deep and round.

Even if table size and girdle thickness were on the report, angles still couldn't meaningfully be calculated (if that's what you are after).

For example, your stone could vary in pavilion angle critically by over half a degree just by having a medium girdle that is borderline thin, to having a medium girdle that is borderline slightly-thick. Bring in asymmetry and non-standard brillianteering and the estimation of angles becomes even less accurate.
