Do ImaGem grading reports contain the same information as the major labs such as GIA and IGI?
Yes, ImaGem provides the universal measures of carat weight, color and clarity and extensive
gauging measures plus a visual image of the stone. However we have not adopted their
recently added models for deciding cut grade. Instead ImaGem provides three
direct measures of light behavior and an overall light behavior grade. ImaGem’s
grading reports provide additional information such as girdle, axial and table symmetry
and girdle perimeter.

In performing color and clarity grading how does ImaGem utilize a gemologist?
The measures and plots provided are always subject to the visual review of a trained gemologist.
Does ImaGem currently offer services to determine if stones are synthetic or treated? If so, please describe?
ImaGem has capability to integrate other systems in its grading process which are used to identify treatment. However currently we do not offer services to determine if stones are synthetic or treated. ImaGem also has proprietary technology to screen for certain treatments.
What does the light behavior image on the report indicate?
The pattern is a visual representation of how a diamond reacts with light and is
a powerful tool for selling a stone. The light behavior image is unique and distinctive to
each diamond and may be used to differentiate it from other diamonds which have a different pattern of light distribution.
What distinguishes this light behavior service from other companies that measure light performance?
ImaGem has developed a system to distinguish between appearances of diamonds based on direct
measurement of light behavior. The direct measurement of light behavior approach takes into account the
color, clarity and nuances in a diamond which cannot be done through a modeling approach.
ImaGem has also introduced intensity as an important measure of light behavior which distinguishes
ImaGem’s light behavior from others. Also ImaGem provides numerical values for brilliance, sparkle
and intensity and a grade based on these values.
ImaGem’s direct measurement of light behavior can evaluate diamonds of various shapes, sizes as well as branded cuts.
Scintillation and fire while historically have been considered in describing the quality of a diamond are difficult to measure
because of lack of operational definition. In ImaGem’s direct measurement of light behavior, aspects of scintillation and fire
are measured by the three measures of light behavior under repeatable conditions.
