United States Patent 6,020,954
Issued February 1, 2000
Method and associated apparatus for the standardized grading of gemstones
Abstract: 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. 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 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.
