"Generally speaking, quality inspection institutions refer to the quality and technical supervision bureau and its qualification inspection agency or the jewelry jade testing station of the local mining bureau or the local mining bureau. Their identification is only targeted at mineral composition. For example, all the lightweight stones can be identified as Hetian jade, and Yunnan Huanglong jade can also be identified as gold silk jade because their mineral components are consistent. " Li Changbao, president of the association, told reporters that the A cargo appraisal certificate can only prove that this is a natural stone, not glass or something else, only proves the true and false, and does not identify good or bad.
For example, Hetian jade belongs to the "nephrite" in jade, but not all nephrite is Hetian jade. There are many places for emergency jade. Due to the different origin and the cause of nephrite, the quality and value of nephrite are also significantly different. Hetian jade is divided into Hetian jade (Xinjiang ingredients), Qinghai nephrite (Qinghai material), Russian nephrite (Russian), Korean nephrite (Korean material), etc. The appraisal agency can only identify some data, and the jade that meets the value of nephrite will have a "Hetian jade" certificate.
This therefore, Qinghai jade, Russian jade, South Korean jade, etc., will have the "Hetian jade certificate", but they are not in the real sense of Xinjiang Hetian jade, and the value is often different.
