Helium Polish 5.2 beta
Previous version Helium Polish 5 (build 5.1.15) contains some critical errors, find their description below. We have fixed the errors urgently and offer to download and use new version Helium Polish 5.2 beta (build 22.214.171.124).
We apologize for inconvenience.
Please pay attention that this is a beta version of program. It is published to fix errors. Now we are working on new version of Helium Polish.
Helium Polish 5.2 beta (build 126.96.36.199) is an update of Helium Polish 5 (build 5.1.15).
Missing data in step cuts
Fourth values of Crown height, Pavilion height and Girdle thickness were missed for some step cuts. This bug is fixed.
Wrong Width value for Pear type cuttings
There was wrong calculation of Width value for Pears, and wrong calculation of values Girdle ratio, Total height % and others correspondent parameters in percents. This bug is fixed.
Changed names of some new pictures and parameters for girdle asymmetry
Please use new names and bookmarks:
Instead of old names:
Please see new names on the screenshot below:
The pictures show real Girdle Length-wise and Width-wise asymmetry, recommendation for Lenght-wise, Width-wise asymmetry and All round girdle asymmetry removal and Girdle asymmetry plot.
1) Pictures Girdle Length-wise asymmetry and Lenght-wise asymmetry removal
Picture Girdle Length-wise asymmetry show real asymmetry.
The blue and red half-round lines show what part of stone need to grind off to get symmetry diamond - you should grind off stone parts between blue and red half-round lines.
1) For example,
if blue half-round line is outer and red half-round line is inner you should grind off left side of stone, if you see from pavilion side*.
2) For example,
if red half-round line is outer and blue half-round line is inner you should grind off right side of stone, if you see from pavilion side.
The numerical values show that mass and area will be loss after grind off:
For left picture Girdle Length-wise asymmetry: if you grind off stone and make it symmetry you will loss 3,29 % area and 0,67 % mass.
After grid off stone by this way you will get symmetry stone by Length only, but the stone will not symmetry by Width. So we recommend to use method All-round girdle asymmetry removing. Read about All-round girdle asymmetry removing in the section below.
2) Pictures Girdle Width-wise asymmetry and Width-wise asymmetry removal
Picture Girdle Width-wise asymmetry shows real asymmetry.
Read description in the section above Girdle Length-wise asymmetry and Lenght-wise asymmetry removal.
3) Picture All round girdle asymmetry removal
Red enclosed line shows future ideal symmetry diamond, blue enclosed line shows real diamond.
4) Girdle asymmetry plot
There are also Girdle asymmetry plot with addition representation of real asymmetry and recommendations of its removing.
The solid green and blue lines show real asymmetry. The dashed green, blue and red lines show: asymmetry with new symmetry axes calculated by software and area should be grind off to make stone symmetry.
So, you can study all three recommendation of removing asymmetry:
and then decide that variant to select for removing asymmetry.
Illustrated report for marquise and oval
Please note, now we have special new Illustrated report for marquise and oval and universal Illustrated report for round fancies for pear, heart and all type of round fancies.
The special illustrated one page report for marquise and oval also contain pictures with real Girdle lenght-wise asymmetry, real Girdle width-wise asymmetry and recommendation for removing all round asymmetry.
All pictures contains numerical values of area loss and mass loss.
Example of new special Illustrated reports for marquise:
Illustrated report for rounded fancies
For cutting, like pear with one girdle axis, one picture Length-wise girdle asymmetry is available only. Also this picture can be used as recommendation for assymetry removing.
Example of Illustrated report for pear:
Illustrated report for cushion
For cuttings like cushion and radiants we suggest recommendation for all-round girdle asymmetry removal:
Example of Illustrated report for cushion:
New bookmarks for pictures:
Girdle length-wise asymmetry -> Actual Length axis asymmetry
Girdle width-wise asymmetry -> Actual Width axis asymmetry
Length-wise girdle asymmetry removal -> Length axis symmetry correction
Width-wise girdle asymmetry removal -> Width axis symmetry correction
All round girdle asymmetry removal -> Both axes symmetry correction
Changes in INI files:
To use option of changing line thikness in pictures you have to use new names of bookmarks in INI file.
