I happen to be from Dalian, and I often do jewelry appraisal certificates.

There is only one national inspection agency in Dalian.

Dalian gold and silver jewelry supervision and inspection center

68-2 Wansui Street, Shahekou District, Dalian

If you pay, the merchant has a business license or the member has a size of 8- 15 yuan.

The cost of personal testing is between 100- 120.

The previous tests were all jadeite, and amber should have little difference.

The above is only the test conclusion and proof, and no appraisal is made for the value evaluation.

It can be tested on the spot, and people don't have to leave, or they can pick it up later.

If you have any questions, just ask.

I hope the answer can help you.
