If you are in Changchun, I suggest you go to Qiyuan Jewelry. Her home is a factory direct store. It is said that she has been in Changchun 18. It was recommended by a friend at that time. Before that, I also learned about the brand of shopping malls. A brand of the same grade has a 50-point diamond ring of about 3-5w. You can come down when you know 1w in Qiyuan. It's a good style. If you want to choose a diamond ring, you can find out and search online.
