In order to make more available methods for natural jadeite quality evaluation, this study applied rigorous coupled wave theory to calculate and simulate the reflection characteristics of various natural jadeites, and establish evaluation standard based on the relationship between refractive index and reflectivity and responses of reflection efficiency to refractive index, grating thickness and incident angles, etc. The results suggest that reflection efficiency varies significantly as a function of the natural jadeite quality, which can provide a new method to evaluate natural jadeite.
