Everything is jade, like this, most of them are made of blue sea material and Russian material, and then covered with gold. Because these two materials can also issue Hetian jade certificates. Of course, the price is definitely not worth that much. It's just a way for shopping malls to raise the original price and provide discounts. A general safety buckle like this, without gold, is only a few hundred dollars. Calculate how much it is worth in gold. The price I said is the market price. Of course, going to the mall is not that cheap. After all, people spend a lot of money, and jade is worthless as long as you like priceless treasures.
