Study on the chemical composition and mineral assemblage characteristics of different - colour jadeites indicates that the jadeite colour has relationship with its chemical composition and mineral assemblage. As jadeite colour changes from while to green, the contents of Cr and Mg elements in jadeite are getting higher, meanwhile the jadeite and omphacite are evolving into diopsidehedenbergite series.
