General appraisal center charges 200 yuan for each piece with an appraisal certificate, and 100 yuan for each piece without one. However, the company appraisal of the jewelry circle shows that 20 yuan ranges from 5 to 1 (including issuing certificates).

So you can say that you used to work in a jewelry company, and I hope the appraisal station can give you a cheaper price and negotiate with them. You can.
