In the jewelry industry, there is such a proverb: "Use a toothbrush, use toothpaste, brush jewelry, and it can be as bright as new jewelry." It is necessary to clean jewelry, but it is not ideal to use toothpaste, because the abrasive hardness of toothpaste containing fine particles is high, and these are very small but the hardness is as high as six or seven degrees (almost, so use toothpaste to wash crystals). The surface damage of jewelry is lower than that of crystal, especially the surface of gold, pearls and K gold. Pearls are absolutely avoided. The most correct cleaning solution should be diluted neutral surfactant. Jewelry can be worn to protect it. It seems simple, but it is not easy. Many people can't help but touch the surface of the gem when they see attractive jewelry. This will affect the luster and brightness of the gem. The human body is on the surface where sweat and oily skin are excreted from time to time, and the hand is the most accessible part of the body. Therefore, the quality of the curved surface is often that the skin, stone and oily hand of the hand can easily stay on the gem, which affects the luster and brightness of the gem. In particular, diamonds are lipophilic gems, and their surfaces are easily polluted by oil, which greatly affects their luster.

However, jadeite belongs to the collection structure, and frequent touching can make jadeite more moist and lovely. Some people want to clean and maintain pearls after wearing them, but they don't know how to use clean tap water, which has little effect on jewelry, but if it is not used to soak pearls. Because there is a fixed chlorine content (C 1) in tap water, it will destroy the luster of pearl surface. In fact, foam should be washed with mineral water. The other pearl will be worn before washing to ensure safety, so as to avoid the discoloration of the pearl caused by dirt accumulation for too long in the future. However, the relative humidity of cash and documents is low, and the storage conditions are not suitable for the tidal properties such as pearls and protein.
