Jade identification: 14 steps to choose good jade
The composition of jade is mainly silicate. The types of jade are jade, Hetian jade, Xiuyan jade, and Dushan jade. The prices of different jade are quite different. Xu Hongliang, a senior jade and jade identification expert, taught the identification method of simple identification of jade. 1, color Color is the most important factor affecting the value of jade. Color is one of the most important steps in the identification method of jade. The color of jade can be evaluated from four criteria: to be pure, to be light, to be clear, to be uniform. 2, transparency Transparency affects the refraction of light, which affects the overall beauty. 3, clarity Clarity refers to the flaws contained in jade, mainly white and black, which are caused by other minerals contained in jade. Relatively speaking, black enamel is more unsightly than white. 4, cut Generally, the requirements for raw materials are high. Except that there is no crack, the ratio of cutting, the thickness of the product and the symmetry are also very important, which is enough to affect the appearance of jade products. The evaluation jade mainly measures its beauty and the fineness of the carving. Usually the jadeite with cracks will be treated in a carved way to cover up the flaws. 5, crack Cracks will greatly reduce the value of jade. If there is a crack in the jade ornament, a slight collision may crack along the entire crack. Jade identification: 14 steps to choose good jade 6, look at the color Observe the color.
