I am now engaged in this jade industry, carving, grinding and polishing. Don't worry, there will be no fakes in the shopping mall, but the quality and price of jade are directly proportional. If you know it, you can see how much it is worth and how much it sells in the market. It's expensive. You can buy it at 1 0,000 in the market, and it may be 1 0,500 to 2000 in the supermarket. This is not fake.
