First, clean and preserve jewelry in time. When not in use for the time being, be sure to clean it up 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. Actually, it's not difficult to clean jewelry. Take a bowl of warm water, add a few drops of neutral detergent, and then gently wipe the jewelry with cotton (or a small brush, such as an old toothbrush). After the dirt is removed, the jewelry can be washed in another bowl of clear water, and then dried in a ventilated place, so that the jewelry can restore its bright color. Necklaces, earrings, pendants and other places with switches or spring devices should also be cleaned and lubricated in time to keep them clean and flexible. After the jewelry is processed, put it in a jewelry box for preservation. When placing, it is advisable to place the gem upward to avoid contact with other objects. If there is no jewelry box, you can wrap it in a clean soft cloth for preservation. Be careful not to put multiple pieces of jewelry together in the same box, and don't wrap multiple pieces of jewelry with soft cloth to avoid mutual wear.

Second, 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.

Third, clear 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. Avoid contact between high temperature and acid-base solution with many gems embedded in jewelry, which will easily fade if 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.
