ImaGem was created after 20 years of research done on human perception and ImageStatistics, a statistical tool developed by Dr. Lalit K.
[1] ImaGem’s Systems employ advanced optics, imaging technology and proprietary software programs to automate and integrate diamond grading.
In addition to evaluating the 4C’s of diamond grading, ImaGem also analyzes Light behavior information based on precise and repeatable measures; three complementary dimensions of brilliance, intensity and sparkle.
[2] By offering all this information, ImaGem has promoted decision-making and efficiency in the gem industry supply chain.
[10] Since a standardized lighting source has not yet been defined, and because of the subjective nature of the process, fluorescence grades in the past have not been repeatable.
Finally, once polished goods are manufactured they require an assessment of their quality based on presence or absence of inclusions.
Some images of rough, polished diamonds and composite ruby illustrate the use of this technology in the gem and jewelry industry.
In the gem and jewelry industry in particular, this technology is used for Kimberley Certification, valuation of an individual of a parcel of rough, identification and for clarity grading.
[17] Brilliance represents average grey scale value of pixels comprising the top view of a diamond.
Intensity (contrast) is a new concept introduced by ImaGem to capture the pattern of dark and bright areas in a diamond.
This particular characteristic is patented and represents an attribute of a diamond that takes into account figure ground segregation essential to human perception.
