Hetian jade seed grade
Do you know the grade of Hetian jade seed material? If you don't know, let's take a look! Introduction of Hetian jade seed material: The original deposit is denuded and transported to the jade in the riverbed. It is transported, abraded and washed for a long time. It is mostly oval, with a small block size, smooth surface and good quality. The seed material is distributed in the terraces on both sides of the riverbed or in the middle and lower reaches of the riverbed. Some of the seeds are partially colored on the oxidized surface. For example, the autumn pear color is called "autumn pear", the tiger skin color is called "tiger skin", and the jujube color is called "jujube skin". The bright color of the seed material is higher, but pay attention to the fake color on the seed. Hetian jade texture classification Special grade The texture is fine and uniform, the grease is strong, translucent or slightly transparent, and there is basically no cracking, impurities and flaws. First level Fine texture, strong grease, translucent or micro-transparent, less than 10% crack, impurities and enamel. Secondary The texture is fine, the grease is weak, the transparency is poor or too transparent, and the cracks, impurities and flaws are less than 30%. Third level Rough texture, waxy luster, poor transparency, splitting, impurities, ç‘•ç–µ more than 30%. Hetian jade color grading Special grade The color tone is positive, no color cast, no variegated color, uniform color, color color should be refreshing and bright, color saturation is suitable, and the color matching is reasonable. First level The color tone is positive, slightly color cast, no mottled color, the color is basically uniform, the color of the color should be refreshing and bright, the color saturation is suitable, and the pretty color is basically matched. Secondary The color is color cast, there is variegated color, the color is not uniform, the color color is dim, the color saturation is low, and the pretty color is basically reluctant. Third level The color is obviously color cast, the color is messy, uneven, the color color is dim, the color saturation is low, and the basic color matching is unreasonable. The color is the artistic creation of jade carving craft, which is based on the natural color and natural shape of jade. The creation of materials and the use of materials are created, and the creation is limited by factors such as material type and color change. The creation of a good-looking work is very difficult and its value is high. In the evaluation of the use of the color, you can analyze the three levels according to the clever, two, and three. When evaluating jade articles with uncoordinated colors and non-conformity, it is necessary to fully realize that it is not a pretty one, but it becomes a "deaf". Not only does it have no added value, but it will depreciate. . The grade of Hetian jade seed material can be divided into two aspects: one is texture classification; the other is color classification.
