Fu Miao jewelry, newly opened, is the cheapest and the largest in Tonglu. There are also customized loose diamonds, which are very good. I just bought loose diamonds and gold, and gold jewelry can be exchanged for free. They also have a special testing area to test the composition of jewelry. You just need to bring your jewelry here, and if there is no problem, you can trade in the old one for the new one, which is very cost-effective.
