2. Even if it is dyed, it depends on the fake process. Nowadays, most of the counterfeiting processes are advanced and have strong color fastness. Boiled in water will not fade. If it is boiled, it will fade, which is a fake. In addition, the real jadeite should not be scalded with boiling water, which may cause damage and cracks.
3. After boiling in water, the texture will become turbid and faded. The banknote detector lamp, that is, the ultraviolet lamp illuminates the jadeite, and there will be no fluorescent reaction on the surface of the real jadeite, which is very natural. However, fluorescent agent is often added to the injected jadeite, so the fluorescent reaction will occur under the irradiation of the money detector. Scrape the jade surface with a knife or other sharp object.
Emerald will fade after a month of blisters. After a month, the jadeite will turn yellow after pickling and injecting glue.
5. Some pickled and glued jadeites will be added with colorants during processing to increase the color of jadeite, so jadeite will be soaked in hot water. When heated, the pickled and glued jadeite will fade, while the natural jadeite will not fade. Pickling and glue injection of jadeite can be distinguished by ultraviolet irradiation.
