Seal Base:皇后之印

Applying partly Dr. Daphne Lange Rosenzweig’s appraisal factors, I am establishing 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.
