Jewelry with bright colors, diverse styles, great aesthetic feeling and high value is deeply favored by modern people, especially women. Jewelry includes diamonds, precious stones, crystals, jadeite, jade and so on. Natural jewelry belongs to geological minerals, with pure color, no impurities and no defects as the top grade. However, if jewelry contains radioactive impurities, it may bring great harm to human body.

Scientific research shows that if jewelry contains radioactive substances that exceed the normal value, the amount of radiation received by the wearer in one year can exceed the radiation limit of a nuclear worker in one year, which will not only easily cause canceration of the skin and muscles at the wearing part, but also increase the incidence of lung cancer and breast cancer, especially some inferior jewelry that has not passed the safety inspection, and its radioactive substance content greatly exceeds the national safety standards, which is extremely harmful. Therefore, to buy jewelry, you should go to a reputable store, ask the salesperson for the quality certificate of jewelry, and keep the purchase invoice so as to provide a basis for future problems.
