Abstract

Methods for upgrading gemstones, apparatus for upgrading gemstones, and system that utilize such methods and apparatus, specifically methods which trace rays (32,33) through a computer representation of a gemstone (20) wherein the rays (32, 33) enter the gemstone through the gemstone crown and allow a grade to be assigned to the gemstone represented based on the ray paths through the representation.
