Applying partly Dr. Daphne Lange Rosenzweig’s appraisal factors, I have established scales for each factor, including rareness, historical and cultural significance, quality of jade, workmanship, size in the range index of 1 to 10 to reach weighted average (It should be noted that the indexes of historical and cultural significance and rareness should overwrite the other indexes). To assign each index a monetary value, we may reach an appraisal value (in addition to the market approach). From the beginning, the index only assigned by myself. In the future, I will try to contact outside experts to have their opinions to practice a Delphi Method approach for the Chinese antique jades appraisal.
<易經>是故形而上者謂之道, 形而下者謂之器, 化而裁之謂之變, 推而行之謂之通, 舉而措之天下之民, 謂之事業. <The Text of Yi King>Hence that which is antecedent to the material form exists, as an ideal method, and that which is subsequent to the material form exists, as a definite thing.
