If you want to do jade appraisal, you can go to Zhejiang Jewelry National Jade Appraisal Center, but it is more difficult to do it, because the appraisal center does not give appraisal, and the merchants will not. Unless you go to Wu Shan Square, the merchants there will only evaluate it when they receive it, but it is generally low.

There is another way that might help you. After identification, if it is jade, you can find a piece of the same kind of jade in a big jade shop according to the specific variety, and then multiply its retail price by 0.3-0.4 and then divide it by the weight (gram) to calculate the price per gram, and then multiply it by the weight of jade in your hand, which basically equals the value of this jade, but because each jade may have new and old pits, impurities, cracks, water color and carvers.
