Support
for different cuts and parameters
|
|
DiamCalc
supports all main cut types and allows to
view/change a large set of parameters, including
advanced ones.
DiamCalc
Standard supports 10 main cut types. There
is a set of cut parameters (diameter, crown
height, ...) which are common for all cuts.
Also there are some advanced cut-specific
parameters, which allow to handle some rare
cuts (for example, old round cuts).
Note.
The free demo-version of DiamCalc supports
Marquise cut only. Although the demo-version
is fully functional, some cut-specific parameters
(e.g. advanced parameters of Brilliant diamonds
- see below) cannot be seen in the demo-version.
The following topics
are available in this section:
1. Working
with different cuts.
2. Working with cut parameters.
3. Advanced
parameters (old cuts, etc.).

1.
Working with different cuts
|
|
DiamCalc Standard
supports the following cut types: Brilliant,
Marquise, Pear, Emerald, Flanders, Happy-8,
Prince, Baguette, Oval, Heart.
The current shape
is shown in "Shape and cut"
drop-down box. Setting a desired cut type
is the first thing that should be done
when parameters of a new diamond are entered.
To change a cut type, click "Shape
and cut" box with a mouse. A list
of possible values appear. Clicking on
a cut type in this list will select this
cut. A diamond image in the left half
of Diamond Calculator window will change,
displaying a diamond of a newly selected
cut.

2.
Working
with cut parameters
|
DiamCalc displays
cut parameters in a parameter panel, which
is located in the right half of the application's
window:
A notebook-like
structure has two tabs: Proportions and
Advanced. Proportions tab holds most common
parameters, such as diamond diameter,
total height, etc. Most values can be
adjusted to describe the stone more precisely.
If only some proportions are known, DiamCalc
assigns reasonable estimates for parameters
that cannot be measured.
There are two different
methods of changing parameter's value.
First, a new value can be entered directly
from the keyboard. To do this, select
a chosen parameter value with the mouse,
type in a new value, and press Enter key
at the end. The other method is to use
buttons that are on the right of each
parameter which value can be changed.
Note that a slider named "Step"
allows to tune the amount by which those
buttons change the value. For example,
when the slider is average (default) positions,
buttons change the diameter by 0.1 mm;
when it is in the "Fine" position,
those same buttons change the diameter
by 0.01 mm.
See also "Selecting
measurement units and parameters to show"
section that describes how to change presentation
of some parameters: select one of available
measurement units, choose one of similar
parameters ("dual" parameters),
etc.

3.
Advanced parameters (old cuts, etc.)
|
The parameters
on Advanced page of parameter panel usually
depend on the current cut. Let us examine
parameters that are available for Brilliant
cut diamonds.
"Square deviation",
"Star facets" and "Lower
facets" parameters describe proportions
that rarely change in modern diamonds,
but can vary in unusual and especially
old cuts. This allows to apply DiamCalc
not only to standard Brilliant cut, but
also to older round cuts.
