1. Counter maintenance: Your necklace has just been bought, so you can check whether it is still under warranty. If so, you can go to the store where you bought it for maintenance. In this case, the store will not charge maintenance fees.
2. Self-welding: This method has low safety. If the welding is not good, it is likely to affect the beauty of the necklace, especially the gold necklace can be seen after welding. The welding place will turn black if it is not polished.
3. Find a third-party professional jewelry repair shop: If the necklace is worn for a long time, after the warranty period, you can only go to some professional jewelry repair centers at your own expense. Generally, large jewelry stores have such services. Or some well-known professional luxury goods maintenance institutions will have experienced jewelry maintenance technicians, who have rich experience and countless successful jewelry maintenance experiences and are quite trustworthy.
