1, color: There are many colors of jadeite, the most common ones are white, green, red, yellow, purple, gray, blue-brown, black and so on. Among them, green is the rarest, so it is the most precious and valuable. Bright and light green is the best green, strong, sunny, positive and uniform is the top grade, pure purple and beautiful red value. A piece of jade coexists with many colors at the same time, which is not only rich in meaning, but also more precious. For example, the coexistence of red and green is called "double happiness", and the coexistence of red, green and purple is called "Fu Lushou". Together with yellow, it has become the "four happy events". If there is a white background, it is precious, and it is called "Five Blessingg".
2. Texture: The background color of jadeite is called "ground" or "seed". The better the transparency, the higher the value. According to the different manifestations of texture structure, the names of "species" or "land" are different. Common seeds are glass seeds, ice seeds, glutinous rice seeds, flower seeds, oilseed seeds, bean seeds, Gan Qing seeds and porcelain seeds.
Glass type: white or other colors, transparent, bright and transparent as glass.
Ice species: the transparency is slightly worse than that of glass, but it is as clear as ice.
Glutinous rice seeds: second only to ice seeds, the color is like glutinous rice and the transparency is not as good as ice seeds.
Flower-green species: green is irregularly distributed in veins or spots, and it is a widely distributed jadeite.
Oil green species: good transparency, fine jade, oily surface, dark green with blue-gray tone.
Bean green land: opaque, yellow-green land. Generally, the grain is coarse and the texture is rough.
Gan Qing species: strong pure green, poor transparency, dry foundation, rough jade and short columnar mineral particles.
Porcelain grinding seeds: mineral particles are white and granular, with poor transparency and rough texture, belonging to low-grade products.
3. Carver: refers to the carving process of jadeite. The value of a piece of jade has a very important relationship with its fine carving technology and ingenious meaning. There is a saying at home called "one kind of two colors and three handiwork". Pure hand carving and different colors of jadeite make each finished product unique. The original stone is buried deep in the bottom, and if it can be combined into one after the crust changes, it is a beautiful jade that is hard to find in the world and is of great value.
