There are many jade jewelry wholesale cities in Beijing to choose from.
The price is cheap, the quality is acceptable, and the color is guaranteed, which is available in all major jewelry cities. It's hard to say where it must be. You need to find it yourself, find your congenial boss and jade. Generally speaking, the shop opened by the boss is much easier to talk about, and the shop opened by the salesperson is often difficult to talk about. Even if people talk well, they may not give you much discount.
Xinjiekou South, Xinjiekou North, the first floor of Tianyi Shopping Mall, Panjiayuan, etc. You can shop around. I often go to Wante in the north of Xinjiekou, the Fifth Ring Road in the south of Xinjiekou, Tianyi and Panjiayuan. Among them, there are many low-end goods in Providence, and those within 1000 are ok; The high-end products in Xinjiekou are relatively better. Panjiayuan is the most controversial. It is true that there are too many fakes, but there are also many real goods. The booth fee is cheap. Every weekend, there are the most people and things. Generally, it is much more affordable to find a single item on Sunday afternoon.
For those who don't know jade, it's best to learn some common sense of jade online first, so as not to know the goods, and greedy people are the easiest to be fooled. Then, be sure to ask for proof, and you can re-examine it online. A certificate is more reliable than no certificate, which is very important for beginners, otherwise it is easy to make holes in high imitation products.
