Increase humidity. The water in the jewelry cabinet can increase the air humidity by evaporation, so that the jewelry will not be too dry. This is beneficial to the maintenance of jewelry and prevents problems such as cracks in jewelry.

2. Prevent rust. High humidity environment can prevent the surface of jewelry from rusting, especially silver jewelry is more likely to rust in low humidity environment.

3. Purify the air. In the process of evaporation, water can adsorb dust and pollutants in the air, thus making the air in the cupboard cleaner and also conducive to the maintenance of jewelry.

4. Prevent charge accumulation. In the low humidity environment, the surface of jewelry is more likely to generate static electricity, and people are prone to get an electric shock when taking jewelry. Being close to water can absorb the charges in the air, thus preventing the accumulation of charges.

5. Beautiful and convenient. Putting a glass of water in the jewelry sideboard can not only achieve practical results, but also make the whole look more beautiful and generous. Moreover, it is more convenient to take water and can be replenished or replaced at any time.

Therefore, generally speaking, it is very necessary and beneficial to put a glass of water in the jewelry sideboard. It can moisten the air, prevent rust, purify the air and release charges. At the same time, it is beautiful and convenient, which has a good effect on protecting jewelry.
