To identify the authenticity of a piece of jade, first of all, we must understand its characteristics. When evaluating grades, Huang Longyu usually focuses on its four physical properties: species, water, color and purity. In the identification of Huang Longyu, we can also start from these four aspects.
Huang Longyu's "species" not only expresses the texture of Huang Longyu, but also expresses people's feelings about jade. Huang Longyu is an aggregate of aphanitic minerals, and the finer the texture, the better. A good piece of genuine Huanglongyu seed material feels delicate and soft, and has the texture of baby skin. Generally, Huang Longyu is divided into gem species, ice species, oil species, frozen skin species, microcrystalline species and snowflake species. "Water" refers to the transparency of Huang Longyu, which is basically similar to the evaluation method of jadeite. "Color" refers not only to the hue of Huang Longyu's color, but also to its saturation. Huang Longyu is dominated by yellow tones, and at the same time, it has a variety of color systems, and each color system will have various saturation levels. "Net" refers to the purity of Huang Longyu, that is, the amount of impurities and cotton it contains. Generally divided into four levels, that is, pure, relatively pure, with impurities and many impurities.
