OctBrill.txt file format
This document shows technical description of OctBrill.txt file format
OctBrill.txt file is located in System subfolder of the folder where DiamCalc is installed. It contains price list for Brilliant cut.
Use a description below as a guideline for understanding the format of OctBrill file. In short, there is a set of tables for different mass groups (i.e. ranges of diamond
mass). Each table defines prices per carat for each combination of diamond color and clarity. The software finds an appropriate
table for a given diamond mass, then gets price per carat for given values of color and clarity from that table.
Let us look at first several lines of the file
; Price list for brilliant diamonds from OctoNus Software.
This line is a comment, as it begins with ';' symbol (semicolon). You can delete it or add additional comments
anywhere in the file, putting them on a separate line and beginning it with ';'. Comments are ignored by the software.
The file consists of a set of tables, each one is for a certain range of diamond mass.
The line above asserts that there are 19 tables. The tables data follows. If you decide to edit the
file or create a similar file, e.g. to add a file for a specific cut type, please make sure that
the number of tables is specified correctly.
After previous line, all tables are listed one by one.
They have similar formats, so let us see only the first one
Format: clarity 8 5
The beginning of this line must be "Format: clarity". After that, table dimensions follow (8 columns by 5 rows).
Mass: 0.01 0.03
This table is for diamonds with mass from 0.01 to 0.03 carat.
This line should be usually left intact. It sets the magnifier coefficient, i.e. if a value other
than 1 will be specified, all prices will be multiplied by that value.
The table consists of the following elements: captions on the left correspond to diamond colors, captions
on the top are clarity values, and the table elements are prices per carat for that combination of
color and clarity. For example, the upper left number (765) is on the intersection of "D-F" line and "IF-VVS2" column.
It means that the price per carat of diamonds with color from D to F and clarity from IF to VVS2 is 765
(all prices are in US dollars).
The other tables are constructed similarly
