There are basically 49 common colors of jadeite. The reason for these colors is that jadeite contains different chemical elements. At present, the research results show that jadeite contains about 58% silica, about 23% alumina, about 13% sodium oxide, about 1% calcium oxide, a small amount of magnesium oxide and iron oxide, and trace elements such as chromium, nickel, zinc and manganese.

When jade is worn on the body for a long time, it will rub against the human body, and trace elements will enter the human body, balancing the level of trace elements in the human body. Zinc in hair can activate insulin, regulate energy metabolism, maintain human immune function, promote children's intellectual development, and have anti-cancer, anti-deformity and anti-aging effects. Manganese can resist the damage caused by free radicals, participate in the synthesis of protein and vitamins, promote blood circulation, accelerate metabolism, resist aging, and prevent Alzheimer's disease, osteoporosis and atherosclerosis. This is the health care function of trace elements in jadeite to human body. You can go to www.bzlgl.com website to learn about jade. I hope the landlord will adopt it.
