At present, there is no authoritative professional appraisal institution in Jiangxi Province. The nearest places to Jiangxi are Guangdong and Zhejiang, but Guangdong has not heard much about antiques. A professional appraisal company has just opened in Yiwu, Zhejiang Province, called Yiwu Wenbo Testing Technology Co., Ltd. It costs 200 yuan to see it. I heard that you can still check jewelry, precious stones and jadeite now.
