Turquoise is best traded on a third-party platform and can be returned. Turquoise is very valuable, you'd better make an appraisal. A string/kloc-0.08 million, only a few hundred dollars for an appraisal. If you don't trust the seller, you can receive the goods for identification. Every city has a jewelry inspection agency. This man is cheating, so he can call the police. This kind of person will strike hard and lose the face of our Shiyan turquoise dealer.
