In fact, any brand of jewelry chain stores will provide necklace repair services. You can go to Chow Tai Fook, Leofoo and other local jewelry stores for consultation. Once I was repairing a necklace with a friend, and her necklace was accidentally torn by her-because the necklace was bought in Ireland and there was no warranty there. So we went to Chow Tai Fook to find someone to help weld. I remember spending time in 50 yuan ... usually starting in 50 yuan, this kind of service.
