This
document show in details how DiamCalc
calculates diamonds prices
DiamCalc
can estimate a price of the diamond taking
into account the mass of the diamond,
its cut, color, clarity, quality of cut
and a user-defined discount.
The following
method is used:
-
Base price per carat is calculated with
price lists using mass group, cut, color
and clarity
- The
final price is calculated on the basis
of base price per carat, mass, discount
for quality of cut and user discount.
Price
lists are stored in text files. The main
file is Price.txt which is located
in the folder where DiamCalc is installed.
The shipped version of Price.txt
file does not contain price lists itself,
but rather has references to OctBrill.txt
file (it is located in the System
subfolder and lists prices for Brilliant
cut) and OctPear.txt file (it is
also in System subfolder and contains
prices for Pear cut).
Price.txt
file also specifies that the price for
diamonds of other shapes is a half of
the price of the Brilliant cut diamonds
with similar other parameters. For the
details of individual file formats, see
the links below. Note that there are three
price list files in the shipped version
of the software (Price.txt, System\OctBrill.txt
and System\OctPear.txt), but formats
of the last two are essentially the same.
