Now there is a solution: complain to Kunming local 123 15 and explain the situation. Then I called the local tourism and shopping association to complain; If you buy jade in Yunnan, you can defend your rights and refund the goods in the following ways: collect complete purchase vouchers, such as small tickets, invoices, receipts, etc.
Learn to disguise: First of all, if you buy jade, don't deliberately show off your wealth, try to dress low-key, or you will be easily "slaughtered". Secondly, you should learn more jadeite jargon before choosing jadeite, so that you can pretend to be an expert when necessary.
I can only say that you are either rich or big-hearted. Old gamblers who buy jadeite stones on the spot will be fooled, not to mention you. I guess no one responded to you. In addition, the appraiser should be professional, even if he gives money, others will be willing. In short, one word is difficult.
Let them communicate with each other, and they will take care of it. Generally, you can go shopping at tourist attractions and return it within 30 days. I am a jade jeweler in Kunming, Yunnan. Many customers come to Yunnan tourist attractions to buy jade quilts, most of which are returned successfully.
