Jade is the common name for two minerals used as gemstones: jadeite and nephrite. Fake jade also exists in the economic circuit. This is worth less than real jade. The two can be distinguished by the fact that real jade changes color over a long period of time when it has been in contact with human skin for years. Jade comes in many different colours: green, brown, black or cloud white, from very light to very dark. Jade, like soapstone and chalcedony, has been cut and worked by the Chinese for thousands of years. Jade was originally used as a tool, but came into use as jewelry during the Han dynasty. The only place where nephrite is found in China is in Sinkiang around the city of Khotan. In Chinese culture, only processed jade is considered valuable. A lump of raw jade is therefore of lesser value. In the Sanzijing it is mentioned as a comparison with education: "If one does not polish jade, it is not a precious thing. If a person does not learn, his life is meaningless, because he does not know the norms, values and respect of life and thus will never become talented" (玉不琢不成器人不學不知義). Jade is seen as a valuable stone that wards off evil forces. If you wear a piece of jade on your body for a long time, for example on a piece of red thread around your neck, you will see that the jade slowly changes color. During the 2008 Olympic Games in Beijing, the medals are decorated with jade.
