Calculate Crown Height %?

[MikeyG]

I do not have my Crown Height % for my diamond and would like to check the specs via gemappraisers.com. Is there a way to extrapuate the figure from the known measurements? Or can anyone give an educated guess? Here is what I know:

.90 Princess
5.27x5.11x3.75
Depth 73.4%
Table 70%
slightly thick to thick girdle.

Also, EGL calls Princess cuts Princess cuts but GIA calls them Square Modified Brilliant or is a SMB something different? I assume they are the same but just curious.

Any help would be appreciated.

Princess and square/rectangular modified brilliant are the same thing. Nobody can calculate the crown height, though. If you have an EGL report you should be able to get it, though. Try to call the lab that issued your report.
