Putting a piece of chalk in the jewelry box can keep the jewelry shiny, because all the ingredients in the chalk can absorb water and keep the jewelry shiny.

Jewelry needs nourishment. After all, jewelry depends on a certain amount of water to keep its luster. Just like human skin, it needs hydration in dry and hot weather. Because there will be a projector lamp above the jewelry counter, the temperature will be higher after a long time of light irradiation, and the air humidity will evaporate quickly, which will dry the air in the counter. The dry air will make the jewelry surface rough, dry and discolored, so putting a glass of water in the counter can keep the air humidity, thus protecting the jewelry.

Some jewels contain a certain amount of water. If the jewelry is left in a dry environment for a long time, the loss of water will darken the luster of the jewelry and even cause cracks. Moreover, when the water in the water cup meets the light of the projection lamp, it will produce reflected light, which will make the jewelry look more shiny and prevent the jewelry from oxidation. Therefore, the purpose of putting a glass of water is to keep water in jewelry and make jewelry look more shiny and beautiful.

In addition, it is not easy to get gray when the humidity is high, and now it means making money. Some jewels contain a certain amount of water.
