Abstract

This paper illustrated how to grade the color of emerald on the basis of CIE1976 L*a*b* uniform color space. In order to test the stability of Color i5 color photometer, sample average color variation was calculated by utilizing CIEL*a*b*color difference formula and the result revealed that it is reliable. Tone of emerald was classified through comparing GemDialogue colorimetric method and instrumental measurement; in addition, merits and demerits of GemDialogue colorimetric were also illustrated during this process. The result showed that GemDialogue colorimetric method has certain fuzziness and subjectivity in color grading and the corresponding suggestions are also supposed. The green tone of emerald was classified into 4 parts by combining sample tone measurements with the drifting of its UV visible spectrum peak (10nm) under uniform color space. Finally, the color of emerald was graded.
