1. Avoid contact between high temperature and acid-base solution and many gems embedded in jewelry, which are easy to fade when exposed to high temperature or sunlight for a long time; Some contact with acid-base solutions can also cause discoloration and even be eroded and dissolved.

2. Check regularly to prevent gems from falling off. Gems embedded in gold and silver jewelry are often fixed with a few gold and silver claws, which is not very reliable. Even if it is inlaid, always check its firmness and handle it in time when problems are found.

3. Take down the collection in time. When you don't need to wear jewelry, you should take it off in time and collect it properly. If you take part in productive labor (field or factory workshop), sports activities, bathing, washing your hair, housework (washing clothes, washing dishes and chopsticks, cleaning, etc. ), jewelry should be removed to avoid damage to precious stones and gold and silver jewelry (impact, abrasion, falling off of precious stones, or corrosion by chemicals in detergent).

4. Wash and save jewelry in time. When you don't wear it for the time being, you must clean it in time before saving it. Some people wear it for many years and never clean it, so that dust and oil stains accumulate in every corner of jewelry, which seriously affects its luster.
