Is this certificate appraised by Zhongwei Jewelry and Jade Quality Inspection Center true? Is it true?/You don't say. How much is it worth?
Zhongwei's appraisal certificate is still credible and should be true, but it depends on what it is. If it's an ornament with gold, jade or 925 silver, it's true, but it's worthless. The normal market price is around 100-200 yuan.
