The Guatemala purple jadeite jade (jadeitite) was studied by such means as thin section, cathode luminescence, LIBS and LA-ICP-MS. The results show that the common assemblage includes jadeite, albite, grossular, titanite and rutile, and the sequence of their crystallization is in order of titanite-white jadeite-bluish purple jadeite+grossular-albite, suggesting the evolution of fluids at decreasing temperature. The blue purple jadeite has higher Ti content. In appearance, the Guatemala purple jadeite shows that the pink purple mass is caused by grossular and the blue purple mass is caused by jadeite with higher Ti content and colorless transparent albite in association with these masses. These characteristics can distinguish Guatemala purple jadeite jade form Myanmar purple jadeite jade.
