I am a student of Dada Jewelry College. Jewelry street is actually the street at the gate. Those jewelry stores are all concentrated at the underground gate. The quality is ok, it must be true, but the things there are not cheap. We've all met them. In fact, you can buy it in the online shop, because many seniors in our college buy it themselves, and it is very cheap to sell, and the synthetic crystal is only a few dozen pieces! Leave me a message if you have any questions!
