More and more people are interested in the quartzite jade mainly due to its rich and varied material colors. However, very limited information is known, particularly on the coloration mechanism. This paper investigated various colored quartzite jades from Huoshan of Anhui Province and Longling of Yunnan Province. The distribution of colors, major elements and trace elements were analyzed by optical microscopic techniques, X-ray fluorescence spectrometer, and ICP-MS. It is found that the colored minerals exist mainly in the fractures and the grain boundaries of fine quartz crystals. The coloration was generated during the post-crystallization stage with the assistance of the iron oxides and hydroxides minerals.
