When it comes to the jadeite market, counterfeiting is common. In addition to the most well-known counterfeiting of goods B and C, bad businesses have invented various methods of counterfeiting jadeite in order to make huge profits. How can we identify the genuine jadeite? Today, let's talk about the strength of experts, sharing appraisal skills.
Identification method of jadeite colored with polishing powder:
This method is much more secret than C goods dyeing jadeite, so it has become a favorite trick for bad businesses to cheat consumers. Because polishing powder is needed for polishing jadeite, and some polishing powder will be left on the surface of jadeite after polishing. If it is purple polishing powder, it will make jadeite look purple. If it is green polishing powder, it will make jadeite green, or the original green part will become darker.
The biggest disadvantage of this method is that the polishing powder does not enter the interior of jadeite, but only stays on the surface of jadeite to deepen its color. Therefore, after wearing for a period of time, the polishing powder will fall off, and the color of jadeite is not as bright as when buying. Therefore, for the identification of this kind of jadeite, one is to magnify and observe the cracks and particle gaps on the surface of jadeite. If you can see the phenomenon of dye dense division, it is the jadeite dyed by polishing powder. Another method is to use a cotton swab dipped in alcohol to wipe the jadeite. If the color falls off, it is the jadeite dyed with polishing powder.
The identification method of 'dressing' jadeite is as follows
The so-called 'dressing' refers to the coating on the surface of jadeite, so it is also called coated jadeite. This method is often used to deal with light color or colorless jadeite, and a green film is plated on the outside of it, which is used to impersonate high-grade green jadeite. This kind of jadeite is not like C or B goods, it will have obvious processing characteristics, so the deception is also very high.
The simplest way to identify "dressed" jadeite is to rub it with your fingers to feel sticky, while natural jadeite still has a smooth texture.
