How to find out the unknown cut parameters?

The simplest way to estimate unknown parameters with DiamCalc is just to enter all known values. DiamCalc will produce a reasonable estimation of other parameters.

In practice, the process can be a bit longer due to the fact that the parameters can affect each other. For example, changing crown angle will lead to a change of either the table diameter or the crown height. Relationships between parameters can be quite complex. To neutralize this effect, it may be required to adjust parameter's value once more after it was automatically recalculated due to a change of another parameter. One more option of handling this problem is parameter fixing.

Another way to find parameters that cannot be measured directly is to examine the diamond image produced by DiamCalc, adjusting parameters until the computer image looks similar to the real stone. See section how to vary lighting and viewing condition for more information. Note that a computing-intensive Photoreal mode is the most suitable for the purpose, so that a powerful enough computer is required to quickly display the image when parameters are changing.
