At present, the precious metal price promotion wars come one after another, some brand stores sell gold jewelry free of manual fees, platinum, inlaid jewelry 60% off and other low-cost concessions, some stores play, "20 yuan per gram straight down" and other people. What is the price of gold jewellery? Why is the price so big? It is understood that the difference in price is mainly in the gold content of the material. Precious metal jewellery gold, platinum, palladium, silver, etc. have a certain value preservation function, and all kinds of simulated jewellery include forging gold, gold and other inexpensive decorations, and the artificial jewellery sometimes fakes precious metal jewellery, in fact, the two are worth The aspects are quite different. In order to confuse consumers, some unscrupulous businesses deliberately help consumers identify the mark and label of precious metals. Simulation jewelry posing as precious metal jewelry The imprint of metal jewellery refers to the logo printed on the jewellery. According to the relevant national standards of precious metals, the imprint contains the manufacturer's code, purity, materials and the quality of the main diamond jewellery. At present, many consumers have a lack of understanding of precious metal jewelry, and the ability to distinguish false and false is weak, the gold and silver jewelry logo is particularly important. How to identify various imprints There are mainly the following types of precious metal stamps: Gold Jewelry Mark: The mark engraved on the gold jewellery should include three parts: the manufacturer, the place of origin and the gold. The jewellery mark is usually engraved on the inner ring of the jewellery, while the necklace is marked on the buckle. Since the state stipulates that all current gold jewellery will be stamped, for example: JY thousand gold, JY is the name of the manufacturer, and thousands of gold represents 99.9% purity. If it is a full gold, it is 99% or more of purity. When buying gold, you must pay attention to the seal. Platinum Jewelry Mark: The mark imprinted on platinum jewelry should include the manufacturer, origin and platinum content. For example, a thousand platinum Pt999, containing platinum 999 ‰, Pt990 means platinum is not less than 990 ‰, Pt900 means that the platinum content is not less than 900 ‰. K gold: The corresponding K number is indicated. The common K-gold jewelry marked "G18K, Au750" in China is 75% gold. K gold is divided into yellow K gold, red K gold, white K gold, color K gold, white K gold is easy to be confused with platinum in appearance, can be distinguished from the imprint. The red gold K-jewelry is made of gold and copper, with a small amount of silver alloy, and the color is reddish. The yellow series of K gold jewelry (referred to as K yellow) refers to the alloy of gold and silver and copper. The gold content can be made into K gold series jewelry with different K numbers, mainly 22K, 18K, 14K, 10K and 8K. . Asians love high-K-gold jewellery, such as 22K and 18K, Europeans and Americans like 14K gold and 10K gold jewelry. The color of the yellow K gold series jewelry is related to the content of gold in K gold and the ratio of silver to copper. The color of 18K gold is yellower than the gold jewelry of 14K and 10K, and the gold jewelry of the same K number is light if the silver is more yellow than copper. If the copper is more yellow than silver, it is deep. Palladium Jewelry Mark: The mark imprinted on palladium jewellery should include the manufacturer, origin and palladium content. For example, a thousand palladium Pd999, palladium content of 999 ‰, Pd990 means that palladium is not less than 990 ‰, Pd900 means that the palladium content is not less than 900 ‰. Palladium is much lighter than platinum and is less than half the price of platinum. The silver mark is marked as S925, which is 925 å« for silver, S990 is 990 足 for silver, and 999 å« for S999. So, what are the simulated jewellery? According to the introduction, the simulated jewellery is respectively gold-plated, that is, the gilt made of copper or silver is coated with a very thin gold GP or KP by electrolysis principle, and the gold-plated jewellery is marked as “GPâ€. Or "KP". In the case of gold, the gold foil is wrapped on the surface of metal materials such as silver and copper. The gold foil is required to have a color of not less than 10K and a weight of not less than 1/20 of the total weight of the material. Forging gold is a kind of gold-coated one. It is forging gold foil on the surface of other metal jewelry blanks under high temperature and high pressure conditions. The color requirement of gold foil is greater than 10K, and the total amount of forged K gold should not be less than 5% of the finished product. It is marked as “GF†or “KGFâ€. The forging gold surface has strong hardness and high wear resistance, and it is not easy to lose the golden texture. Yantai Belief Cap Co.,Ltd. , https://www.beliefcaps.com
