Hello. If you want to buy it in a jewelry store, the more expensive the quality, the better. There is no cost performance. The prices of jewelry stores are all in the market. So generally, the better ones will be very expensive, and the smaller ones will be tens of thousands. If it's online shopping, I hope you don't do it if there is no store you trust in particular. It is easy to buy things that are not worth bidding for. Now many WeChat friends sell them. As long as they have acquaintances, the goods will be cheaper than jewelry stores and will not suffer.
