Apparatus and method for grading, testing, and identifying gemstones

Image Number 7 for United States Patent #6239867.

A method and associated apparatus for the standardized grading of gemstones is provided. The system gauges the spectral response of a gemstone subject to a plurality of incident light sources within an imaging apparatus. The operation of the imaging apparatus is controlled by an instruction set of a local station control data processor. Light energy data is captured in the form of pixel data sets via a charge coupled device of the imaging apparatus of the local station. The control data processor of the local station is operable linked to an analysis station, the station includes an analysis data processor and mass storage memory device. The memory device provides storage space for the instruction set of the analysis data processor as well as database records. The analysis station employs a data processor and model database for assessing the aesthetic and/or monetary value of gemstones by way of the communicated pixel data sets. Gemstones qualities are analyzed by the plurality of light sources of the imaging apparatus and quantified relative to model pixel data sets of the database and recorded for future reference therein.
