    • Abstract
  • Based on the optical observation and X-ray powder diffraction, the compositions of Qinghai nephrite jade are studied. The results show that Qinghai nephrite jade contains wollastonite commonly, which is different from Xinjiang nephrite jade. Wollastonite enhances the transparency of Qinghai nephrite jade and reduces its luster. The wollastonite may be one of the main reasons that influence the quality of Qinghai nephrite jade.
