Fine Tuning with
the Ideal-Scope
|

Figure
9.
The old cut on the top left has big bold fire, but is not as brilliant overall as the ideal cut on the right. The 3 ideal cuts have their lower girdle or half lengths increased from left to right. Stones with shorter LG’s have more fire but less brightness. Plan the best lower girdle length for different table sizes with Ideal-Scope. |

Figure
10. Fine
tuning star width with lower girdle
length & table size results in
improved performance, with very little
weight change. The green line represents
the best range. The red line indicates
stars that are too thin or too thick.

After
polishing, OctoNus and Sarin scanners
can build a 3D model which can be converted
to realistic and Ideal-Scope images
with DiamCalc. These image files are quite small and can be web hosted or emailed and viewed by customers or consumers using a free GemReader download program. Available From (Free Trial Version) www.gemology.ru/octonus/english/gemreader/ This shows Ideal-Scope, DiamCalc, light return etc. With it customers can make movies to compare various diamonds. |
