Natural jade refers to true jade, which refers to the untreated chemical jadeite extracted from the Myanmar mining area. Only this jadeite can talk about the collection and investment value of jade. The coated jadeite is a kind of fake jade in the jade, and the coated jade is also called "dressing jade" or "set color jade". The jadeite after the coating is especially similar to the natural jade. The color and water are also very good. Like the high-end jade jewelry, the camouflage and deception are relatively large, so consumers are buying high-end jade ring. When you face and jadeite, you must pay attention to it and recognize it carefully. The method of making coated jade: choose a transparent, but colorless emerald ring, and apply a thin green film (colloid) on the surface of the jade. The identification methods of coated jade and natural jade are as follows: 1. You can observe its color with a magnifying glass or microscope. If you see that the green of the jade is only on the surface of the jade piece, it is a fake, the true jade color will be combined with the jade. 2. The interior of natural jade is colored and green. Most of the coated jadeite is not available, and very few coatings may be green, but they are especially rare. 3. The hardness of the film is relatively low. Therefore, very thin rubbing scars are often seen on the film, and natural jadeite does not have such a phenomenon. 4. If the surface film of the jade or the jade piece is sprayed with a water spray paint. The refractive index of this film is different from the refractive index of natural jadeite, and it can be tested to conclude. 5. Touch by hand. The surface of the natural jade is smooth when touched by hand, and some of the coated jade has a sense of sorrow when touched by hand. 6. Scrape with a knife. The hardness of jadeite is 6.5-7, which is higher than the hardness of the blade, so if it is natural jade, it will not be scratched with a blade. If the coated jade color film is scraped with a blade, the piece will fall off. 7, wipe. Wipe with a cotton ball containing alcohol or xylene. If there is dye on the cotton ball, it will be coated with emerald. Natural jade will not fade. 8, fire. Burning the surface of a jade with a match or other fire, if the film will change color, it is a fake. Usually, natural jade is nothing to react and change. 9, hot water. It is good to soak the jade with boiling water for a while. If it is coated with jade, the film on the surface will wrinkle or wrinkle due to thermal expansion. Among the eight methods, the method of knife scraping, fire burning and hot water can not be easily used. After all, these things will cause certain damage to the surface of the jade, and this method can be used only after the permission of the merchant or the owner.
