Leonid,
if there is no such formula, how come the DiamCalc program is able to calculate (or rather, approximate) the angles from the GIA dimensions? ..just asking.

One can play with crown and pavilion angles knowing carat weight, depth, table, measurements, girdle, and culet using DiamCalc. However, there might be more than one solution.
For instance, a report says 'thin to sl.thick' girdle. But this is just min and max. You don't know what the average thickness is.
Or measurements 6.50-6.56 mm. Again it is just min and max diameters. We don't know the average diameter or whether it is slightly oval or square.
Hope this make sense.
