To estimate the
diamond mass with DiamCalc, one should
choose a cut style and input the main
parameters (e.g. the diameter).The stone
mass is promptly displayed in the relevant
field. The other parameters should be
specified for more accurate weight estimation.
Let us see how
it is done. Start DiamCalc and look at
the panel with parameters. All parameters
have some values. Marquise cut is selected
initially (see "Shape and cut" drop-down
box). Initial diameter of the stone is
6.00 mm (assume this is what we need).
Now we can enter all parameters that we
know to describe the diamond as precisely
as possible. To change a parameter, select
a value in the corresponding box by the
mouse and type in a new value, pressing
Enter at the end.
For example, let
us set a different value for the total
height. Select a field right to "Total
height" caption. At this moment, the panel
with diamond parameters should look like
the following:
As one can see,
the current value of the diamond's total
height is 61.2% (of the diameter), and
the mass is 1.61 ct. Now when the total
height value is selected on the panel
above, type 62.1 on the keyboard to increase
the total height to 62.1% of the diameter.
Press Enter key. DiamCalc will recalculate
all parameters and the panel with parameters
will look like:
Note that the diameter
remains the same (6 mm), both crown and
pavilion heights have increased proportionally
to accommodate to a total height increase,
and the mass has been recalculated using
a new piece of information: 1.65 ct.
Other parameters can be changed the same
way: select the corresponding value, enter
a new one from the keyboard and press
Enter key.
