1, Hello, I've been to the Mineral Jewelry Appraisal Center on the 9th floor of the Galilee Express Hotel in Anwenyi Road, Xi (not entering the city gate). This is from Shaanxi Provincial Quality Supervision Bureau (national level). General pendant 30 yuan, bracelet 40 yuan. The certificate needs to be added with 10 yuan. Yes, I recommend you to go.

2. The 9th floor of Galilee Expressway is north of Wen Yi Road. You can see that this is a national secondary. There is no problem in the detection of Xi 'an Geology Mine outside Heping Gate, but this is the first private detection fee at the provincial level. The second one in 30 yuan seems to be 100. I can't figure it out. National inspection 30 provincial inspection 100. .

3. Accept and implement the supervision and inspection tasks of precious metal products of jewelry and jade issued by superiors, accept the entrusted inspection of jewelry and jade ornaments by consumers and jewelry-related enterprises, and issue inspection reports or appraisal certificates. The main tasks are: 1. To undertake the quality supervision and spot check tasks assigned by superiors.

4. Hello, judging from the current pictures, I don't think it is necessary to find a testing agency. Visually, the luster is dim, the structure is unclear, and the scattered color is obvious. Visual inspection can basically be judged as unnatural (not a). If you must go to the organization, you can use the map search: Xi 'an Jewelry Inspection to pick one near you.
