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.

Extended data:

Necklace is a chain jewelry made of gold, silver and jewelry. It is one of the ornaments of human body and the earliest jewelry. Some necklaces not only have decorative functions, but also have special display functions, such as prayer beads of Buddhist disciples and Catholic cross chains.

Necklaces also need maintenance, and the following aspects should be paid attention to in normal maintenance:

1, jewelry can't be put in the same jewelry box, because they will scratch each other when put together, so they should be put in different places separately. It is best to wrap them in cloth to prevent the ash layer from entering.

2, wash your face and take a bath, remember to take it off, do not touch acid and alkali substances and cosmetics.

Just as we need to make a mask every week, jewelry should be cleaned. Warm water should be added to household neutral detergent, and the necklace should be lightly brushed with a brush. Then dry it with a cloth.

4. If it is a gem necklace, pay attention to see if there are any signs of looseness.

Be sure to take it off when sleeping, so as not to crush the necklace and make it deformed and broken.

6. Pay attention to the spring buckle when wearing it, because it is the easiest place to break, so be careful.
