Analysis reveals high chromium and manganese in jadeite, suggesting these elements are key to its pigmentation.

Manganese and chromium concentrations significantly affect jadeite coloration, contributing to its value and uniqueness.
Cr2O3 levels range from 46.18% to 67.11%, while MnO concentrations are between 1.68% and 9.13%, indicating rich chromite presence.
The study utilized advanced methods including polarized microscopy, micro-XRF, and electron probe microanalysis to confirm elemental compositions.
Findings may influence the understanding of jadeite's formation and its market value, emphasizing the importance of manganese and chromium.

Zhang et al. (2025) studied this question.
