1. Maintenance within the warranty period. If your gold necklace has not passed the warranty period, you can take it to the original store or chain store for repair.

2. Go to the gold shop for repair. If it takes a long time, you can choose to go to the gold shop for repair. Generally, large gold shops have after-sales service for repair or replacement. The specific cost depends on the location and degree of your necklace break. If it is a gold necklace, the repair cost is generally only tens of yuan. If it's the W button, if you want to add gold, it should be calculated together with the manual fee. Of course, there are still some that can't be repaired. It depends on the specific situation. You can also choose to go to a jewelry store, but the price there is more expensive.

3. Welding by yourself. If you don't mind the beauty, you can repair it yourself, or find a fitter and a handy person to pick it up, but the quality is hard to reach the kind repaired in the shop. But you can see the welded gold necklace, and the welded part will turn black if it is not polished.

4. Change a necklace of the same quality. If you care about beauty, I suggest you change it to the same weight, or you can change it directly from the place where you bought it, but you'd better observe how they do it and avoid reducing the weight of gold or adding other things to it.
