You can go to a jewelry store like Chow Tai Fook for identification and pay some fees. To be an expert, if you have something to do with jade, you may be able to buy it for a small fee. If you have nothing to do with jade, you will spend a lot of money. If you buy it, it will only be a big blow. If I buy jade, I will go directly to the processing factory to pick it, or go directly to Tengchong, or not to buy it. Once bought, buy the most original and authentic jade, which is priceless.
