Hello, there is a jewelry appraisal agency in Hangzhou. Hangzhou went to Zhejiang Jewelry Testing Center and the Ministry of Geology and Mineral Resources, referred to as Zhece. Zhejiang inspection is opposite the downtown Chinese medicine hospital. It used to be convenient. There is Wulinmen Station on Metro Line 2. Find Zhejiang jewelry when you arrive. You can ask the clerk. It's on the seventh floor behind them. Working hours are open on weekdays. For example, do not go on weekends and holidays. Man is the system. The price is not cheap either. The spoken language 100 yuan, one certificate for 200 yuan.
