do you know? Some of the amber is re-melted with debris (Figure)
Natural gemstones such as amber are very popular among people, but industry veterans say that many of the chips on the market are re-melted after processing, and the dispute between the real and the fake is very controversial.
In a shop selling amber in a gold gem trading center on the edge of the Purple Mountain Scenic Area, the price of amber varies from a few thousand to tens of thousands. "Is this reprocessed, or natural? Natural, natural amber, we all have certificates. Secondary processing on the market, secondary synthesis, more. Now amber prices are high, there are many people who fake." Fushun Amber is as famous as Burmese jade, and Fan Yong, the director of Fushun Amber Research Institute, recently visited Nanjing. The reporter asked him to consult him. He is a master of Liaoning amber appreciation and himself collects. He said that amber is a natural organic gemstone, and some materials of some lawless elements are copied, and it is a kind of counterfeiting. "The main thing is to use plastic, glass, for example, celluloid, some natural resin, imitating the amber color. This kind of thing is not with the amber, there is no amber gem feature." Fan Yong said, in addition to fake amber, There is a re-creation, and there is now a lot of controversy in the market. “Reconstituted amber is made of pure natural amber particles or powder, which is melted by high temperature and re-bonded under pressure. It is characterized by pure amber, but it is not amber. It is called amber, or synthetic amber. Its value is much worse than natural amber, but it is still amber. For example, I have poor economic conditions, or I like amber, and can not afford natural, it is also very beautiful to play. It also has the characteristics of amber gemstones." Fan Yong said that some fake fake amber and "sub-amber" Coba can be used to make it appear in a few ways. First, prepare one to four brines for density comparison. The sinking is definitely not natural amber, but in addition to natural amber, there is also the same family of Coba, which is also buried in the underground resin, but the geological time is not enough. If the cultivation is not at home, it can only be called "Asian Amber", and there are also benzene compounds. "Using ultraviolet fluorescent lamps, the money detector can also be irradiated. The surface of natural amber has a blue-white, blue-violet or yellow-fluorescent color, while plastic and benzene composites do not, but coba resin also has fluorescence. How to identify amber and coba resin, the surface of the amber is relatively smooth, Coba resin you rub it with your hand, it is sticky, sticky."
