If it is the quality problem of the earrings themselves, you can take them to the counter where you bought them. During the warranty period, anyone who meets the replacement warranty conditions can go to the counter to replace or repair. General gold and silver shops can carry out welding maintenance, and you can also go to the place where you buy it. No warranty does not mean no repair. Of course, you can also try to weld by yourself, adjust the size of the torch flame, aim the torch flame at the place to be welded, and then polish the welding place with a file and sandpaper.
Generally, tremella nail pin can be welded with a welding gun when it is broken, but some platinum, gold or rose gold ear studs are broken, which requires higher temperature and more complicated operation. In the face of these situations, it is suggested that earrings must be sent to a professional luxury maintenance agency for professional jewelry repairmen to help you repair them.
