Abstract
The color of serpentine jade is affected not only by the chemical composition, but also by some external factors. In this research, we quantitatively analyzed the color of serpentine jade and the influence of light sources, backgrounds, and thickness on its color. Thirty-six gem-quality serpentine jade samples from Tai’an, Shandong, China, were studied using eighteen Munsell neutral gray backgrounds, and three light sources (D65, F2, and A). It was found that the D65 light source appeared to be the most suitable for the display and sale of serpentine jade and the Munsell N9 background can make the color grading of serpentine jade more effective.
