There are 4 main diameters of the whole model. These diameters are
measured as usual using main pavilion facets for
determining the directions of measurement. Azimuths of each pair of
opposite main pavilion facets define the direction, in which the main
diameters are measured. The software does not calculate average,
minimum, maximum values for these 4 parameters.
Rounded Fancies (Marquise, Oval, Pear)
Only two main diameters of the whole model are measured for the
rounded fancies cuts: along minimum and maximum main diameters. These
diameters are measured as usual using main crown facets for
determining the directions of measurement. Azimuths of two pairs of
opposite main crown facets define the direction, in which the main
diameters are measured. The software does not calculate average, minimum, maximum values for these 2 parameters.
