Abstract:
A method of testing the color quality of a colored gemstone is disclosed, taking the gem color as an entirety visually composed of different color components, whose total amount of color components is constant, so as to calculate hue-purity, color-strength and relative chromaticity of the gem color to test the color quality. The method comprises the following steps: (1) determining blackness, chromaticness and hue of the gem color; (2) calculating the hue-purity, color-strength and relative chromaticity in accordance with the blackness, chromaticness and hue; (3) finding a matching color in a pre-established standard color library for this specific gemstone according to the hue-purity, color-strength and relative chromaticity calculated in step (2), and use the name of the matching color to indicate the gem color and color quality.

Claim (Index 9):
The method of establishing a standard color library for a colored gemstone according to  claim 3 , wherein said identifying, classifying, quantifying and defining in said step (4) also includes using natural color nomenclature or said hue to name specific colors represented by said colored gemstone samples.
