1. Keep the environment moist: put the jade in a moist environment, such as using a humidifier or putting a basin of water next to the jade. This can increase the moisture in the air and keep the jadeite moist. But be careful not to let the jade stay in a humid environment for a long time, so as not to cause the jade to become moldy or discolored.

2. Replenish water regularly: every once in a while, gently wipe the jade surface with a soft cloth, and then soak it in clear water for a period of time to replenish the water inside the jade. This can keep the luster and bright color of jadeite. But be careful not to wash jadeite with hot water or strong acid and alkali solution, so as not to damage the surface of jadeite.

3. Avoid direct sunlight: Long-term direct sunlight will lead to dehydration and dryness of jadeite, so try to avoid exposing jadeite to sunlight. Emerald can be placed in the shade or protected by a parasol. In addition, jadeite can be coated with a thin layer of paraffin oil regularly to keep its luster and prevent water loss.
