Jewelry bought at Lukfook Jewelry can be taken to any Lukfook Jewelry Store for the master to check first. If it can be repaired on the spot, you can ask the master to repair it. If it can't be repaired on site, I can help you take it back to the factory for repair. This may take some time. Liufu Jewelry belongs to the National Association, and every store has the obligation to help you solve the problem. You don't have to worry about replacement, because the jade pendant you bought has a certificate.
