For the novice jadeite, the simplest and most effective way is to go to the local jadeite quality inspection center for inspection, and take the appraisal certificate and jadeite to the inspection center for inspection. If it is early, the results can be produced on the same day and the structure can be produced three days later. Regular jade testing institutions are recognized by national authorities, and the accuracy of appraisal results is particularly guaranteed. If there is a problem with the authenticity of jade, the test results can also be used as evidence to sue bad businesses.
2. Look at the color.
A Huoyu is a kind of natural jade with colored roots, which is natural but unevenly distributed. The color root does not mean that the color of jadeite has roots. Simply speaking, it refers to the dark green "living spot" inside jade, which is the flaw of jade. It can also be said that the color root of jadeite is the phenomenon that the colors in jadeite gather together. The older one is called "Moss". Dyeing jadeite is to immerse the dye into jadeite seeds for dyeing, so the color of dyed jadeite will be scattered in a net shape, and more colors will float on the surface.
3. The internal transformation of jadeite is obvious.
Natural jadeite is not perfect, but more like patchwork, so there will be obvious boundaries between too many colors and transparency of jadeite. There is no denying that there is indeed a kind of best jade transition jade that is natural and even, but the price is also very expensive. Jade B is chemically cleaned, and the internal defects are cleaned before dye is injected, so the excessive color is extremely natural and harmonious. The common jadeite boundaries in the market are obvious, so be very careful if you encounter jadeite with natural transition and low price.
4. Look at transparency.
A jadeite is a product of nature and has certain spirituality. We see that ice jadeite has a glass texture every day, but it is very aura when it is foggy inside. Emerald B is a kind of jadeite with poor water quality. After cleaning, resin is injected to improve the transparency. Therefore, Jade B looks dull and muddy inside, and it has a very uncoordinated feeling.
5. It depends.
It is normal for natural jadeite to have internal defects, including cotton, cracks, particles and impurities. Emerald cotton refers to tiny transparent white minerals with patches, filaments and ripples inside jadeite. The crack of jadeite refers to the crack formed by the collision of jadeite due to rock movement. Tattoos are "scars" formed after cracks heal. Impurities are particularly ugly colors or black spots in jadeite, such as black spots, dark spots, khaki, grayish black and so on. , commonly known as dirty color. Normal jadeite is not flawless. If a piece of jade is flawless and transparent and green like glass, it is either sky-high or fake.
6. Flying wing.
"Flying wing" means that the jade surface is bright white and reflective under the irradiation of light, like flying wing. This is because the internal crystals of jadeite often appear as long strips or irregular sheets, which are caused by the reflection of cleavage plane. If jadeite appears, it can be judged that jadeite is real, but its texture is rough.
7, illuminate purple light.
B jadeite is soaked with chemicals, and a large amount of dyes are injected into jadeite. When a large amount of dye remains in jadeite, fluorescence will appear under the irradiation of purple light. In this case, natural jadeite is absolutely impossible.
