This showed that the main peak position of the transmission light is between 530-540 nm, and the color saturation is about 80%. The dense green color of the uvarovite sample is caused by its higher color saturation. The theoretical analysis of the mechanism of the green coloring of uvarovite indicates that the transition of 3d-orbital electron in the Cr(superscript 3+) is responsible for the green color.
