1. Hello, jadeite can be identified in many places in Guangzhou. I know that the nearest to Huangpu is Guangdong Jewelry and Precious Metals Testing Center, which is located in the comprehensive testing building at No.751Dongfeng East Road. The telephone number is 876215987694189-820.

2. In Guangzhou, there are really few places near Huangpu. There are many Hublot Plaza in changshou road, and the most authoritative one is the National Inspection of Panyu Shawan Jewelry Industrial Park Complex (NGTC). I hope it helps.

3. There is a jade appraisal institution in Guangzhou, which can really be appraised. So there is a jade appraisal institution in Guangzhou, which I think is more reliable.

Guangzhou is a city with active jade trading. There are 6 authoritative appraisal institutions with national qualification certification, one in general 10 yuan, and they issue appraisal certificates. The specific address and telephone number can actually be Baidu-Guangzhou Jewelry and Jade Appraisal Center, and there will be results.
