Abstract
Systems and methods, for the evaluation, grading, and presentation of evaluation results, of the scintillation of gemstones, such as diamonds. Specifically, there are discussed systems and methods for determining when a scintillation event in a gemstone is likely to occur and for mapping such events to a presentation.
Claims22
A method to evaluate scintillation in gemstones, the method comprising:
- acquiring the angular spectrum of a gemstone by tracing rays to the gemstone from a point of observation in relation to the gemstone;
- propagating the rays in the stone till they exit the stone;
- determining a region of a hemisphere arranged about said gemstone that said rays intersect;
- and
- coding an image of a virtual facet propagating said ray according to said region that said rays intersect.
A method to evaluate scintillation in gemstones, the method comprising
- obtaining a diagram of the virtual facets of said gemstone;
- and
- coding each of said facets based on its size.
A system for evaluating scintillation in gemstones, the system comprising:
- a computer, said computer being provided with a virtual image of a gemstone;
- means in said computer for acquiring the angular spectrum of a gemstone by tracing rays to the gemstone from a point of observation in relation to the gemstone;
- means in said computer for determining a region of a virtual hemisphere arranged about said gemstone that said rays intersect;
- and
- means in said computer for coding an image of a virtual facet propagating each of said rays according to said region that said rays intersect.
A graphical display of a scintillation potential of a gemstone, the display comprising:
- A color-coded image, the color coded image being generated by:
- providing an image of a gemstone, said image showing virtual facets of said gemstone;
- acquiring the angular spectrum of a gemstone by tracing rays to the gemstone from a point of observation in relation to the gemstone;
- determining a region of a virtual hemisphere arranged about said gemstone that each of said rays intersect;
- and
- color coding said image of a virtual facet propagating said ray according to said region that said ray intersects.
A graphical display of a scintillation potential of a gemstone, the display comprising:
- a coded image, the coded image being generated by:
- acquiring the angular spectrum of a gemstone by tracing rays to the gemstone from a point of observation to said gemstone;
- determining a region of a virtual hemisphere arranged about said gemstone that each of said rays intersect;
- selecting a source on said virtual hemisphere;
- coding an image according to how many rays intersect that region,
- repeating said steps of selecting and coding for a plurality of sources.

- determining a region of a virtual hemisphere arranged about said gemstone that each of said rays intersect;
- selecting a source on said virtual hemisphere;
- determining how many rays intersect that source;
- repeating said steps of selecting and determining for a plurality of sources on said hemisphere;
- and
- evaluating the scintillation of said gemstone based on said repeating.
