The Shuowen Jiezi [說文解字; Explaining Graphs and Analyzing Characters], compiled by Xu Shen during the Eastern Han dynasty and presented to the imperial court in 121 CE, is the earliest surviving systematic dictionary of Chinese characters and a fundamental source for the historical study of Chinese writing. The work analyzes approximately 9,350 characters, with more than 1,100 variant forms, arranging them under 540 graphic radicals and explaining their forms, meanings, and, where appropriate, pronunciations. Xu Shen classified characters according to traditional principles of character formation and frequently drew upon ancient scripts and early textual usage. Of particular interest to gemologists is the extensive treatment of characters associated with jade, minerals, stones, metals, colors, and other natural substances, particularly those grouped under the jade radical 玉. These definitions provide important evidence for the terminology, classification, and perceived properties of jade and related materials in early China and are invaluable for interpreting mineralogical and gemological terms occurring in ancient Chinese texts.
