Generally, there is not much water in the window of gold and silver jewelry, and the basic water is in the window of jade. The main reason is that when displaying goods in the window, in order to make the goods look more beautiful and stimulate customers to buy jade, small spotlights are installed at the corners, and the lights are refracted on the goods, which are very eye-catching and beautiful. But these spotlights will have temperature and will dry the air moisture in the closed space of the window. If it is too dry, jadeite is easy to crack, so in order to solve this problem, a glass of water will be put to avoid the above situation.
