Many people will ask: "What jewelry jeopardism is the most on the market?" In China, and even the whole world, Xiao Bian has to say: "What is hot and what is fake." In recent years, amber has been popular because of its rarity, resulting in price. As the number of climbs rises, of course, fakes are endless, and the following is a brief introduction to the China Jewelry Merchants Network . Amber market fakes There are many ways to fake amber in the market. Take amber imitation as an example. There are two main imitations: 1. Amber is impregnated with Coba resin and hardened modern resin. It is usually used as amber with some old-fashioned Coba resin and some non-coniferous resins produced by coal mines. 2, using a variety of plastics to imitate amber, these plastic replicas are particularly common, and quite realistic. Many people believe that foreign things are more fidelity, but they are not. Buying high-end jewellery overseas should try to avoid informal tourist souvenir shops or markets. When buying jewelry, the merchant must be required to issue a formal invoice. The invoice must be marked with the name and level of the gem in Chinese, and whether it has been manually processed, and even the promise of the merchant can be written on the invoice. "Second-generation amber" There are many "second generation" ambers on the market. There are many ways to reconstitute amber. The common method is the smelting method, which adds some special chemicals and additives to the amber crumb, and then melts through high temperature and high pressure, and then solidifies into large pieces after cooling. In addition, there are two or a few larger ambers, which are processed into a larger piece of amber. The most important feature of this type of "second generation amber" is that its raw material is natural amber, so its physical and chemical properties are comparable to natural amber, even if it is placed in saturated brine, it will rise. Because of this, the brine method is not a reliable method for identifying amber. In the absence of instrumental conditions, it is up to the experience to distinguish by the naked eye. The bubbles contained in natural amber are generally round, but the bubbles in the regenerated amber usually become elongated. The texture of natural amber is relatively strong, and the texture of reconstituted amber is a typical syrup. In addition, the price is also an important factor in distinguishing between natural amber and reconstituted amber, which is 75% more expensive than reconstituted amber. 100 yuan of true amber, "second generation amber" as long as twenty or thirty yuan. Although it is not necessarily natural products above this line, below this line, it is basically fake. In the identification, it was found that such amber appeared at the jewelry exhibition, and it was found that the fake was not found again. Therefore, consumers are advised to buy at a large jewelry sales outlet. In addition, it is best to have a certificate from a large appraisal institution such as Peking University, “National Inspection†and “Guo Shouâ€. To purchase a collection of amber, you can use the following methods to identify the true and false of amber : 1, smell it Generally, natural amber has a rosin flavor when punched. Unfinished amber rough stone can be smelled with a special scent after being heated by hand. 2, fluorescence The amber is placed under the money detector and irradiated with ultraviolet light. The natural amber emits green, blue, white and other fluorescence, while the plastic fake amber does not change color. 3, soaked brine Prepare a 1 to 4 saturated saline solution, place the amber in saturated brine (except Coba resin), and the plastic product will sink. 4, hot needle exploration Heat the needle on an alcohol lamp and try it in the secret of amber. Amber is a pine scent and plastic is a spicy scent. 5, see the structure Look at the natural inclusions: plastic imitation beeswax will have a more obvious fluid structure. Although amber has a similar structure, it is different from plastic. Learn more about amber and pay attention to China Jewelry Merchants Network - Jewelry Culture.
