US Patent:

Filed:

Nov 28, 2006

Appl. No.:

11/564048

Inventors:

Jose Sasian - Tuscon AZ, US
Jason Quick - Las Vegas NV, US
Jason Flatt - Las Vegas NV, US

Assignee:

American Gem Society - Las Vegas NV

International Classification:

G01N 21/00

US Classification:

356 30, 703 2

Abstract:

Systems and methods for evaluating an optical property of a gemstone operate to trace selected and ordered model light rays through a model of the gemstone. The rays may be selected such that, when ordered into a sequence, the points of contact of successive rays with the gemstone surface generate a pattern defined by a path created by the linking of successive contact points with line segments. Further, the rays may be propagated through the gemstone in a manner that utilizes an ordered set of facet identifiers corresponding to facets impinged upon by a ray previously propagated through the gemstone. Moreover, these strategies can be combined by propagating an ordered sequence of rays corresponding to an ordered set of contact points generating a pattern defined by a path, and using for such propagation an ordered set of facet identifiers corresponding to facets impinged upon by a ray previously propagated through the gemstone.

Peter Yantzer - Las Vegas NV, US

Assignee:

American Gem Society - Las Vegas NV

International Classification:

G01N 21/00

US Classification:

356 30

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.

International Classification:

G01N 21/00

US Classification:

356030000

Abstract:

Systems and methods for evaluating and displaying a diamond's dispersion or fire potential. These systems and methods can be used to determine the dispersion of a diamond relative to an observation point, which can then be used to provide for a map or other indicator of a diamond's fire potential when it is observed from that point.
