3 thoughts on “Will there be fake gold in the gold shop”

  1. In general, there are no fake gold shops, but some gold shops have fake gold, which depends on the reputation of the gold shop. It is not 100%, but it is a specific content
    first, gold jewelry is easy to participate in counterfeiting, so it is best to choose famous brands when buying, because it is difficult to distinguish the purity. Generally speaking, big brands and supermarkets can meet the requirements
    the probability of counterfeit gold sold in some gold stores of major brands is very low. After all, these brands have been established for many years and have large and small branches all over the country. In case of counterfeiting, it will be exposed and closed. But not everything is absolute. There was a storm in a brand gold store. At the 315 party in 2013, CCTV officially exposed the news of gold counterfeiting of a certain brand. Because a buyer had a channel to test gold, he suddenly wanted to test it after buying gold, but found that the purity of gold purchased in the brand store was not 100%, only 997.7%, which was immediately exposed
    now, when you go to the gold store to buy gold, it is three nines or thousands of gold. It is difficult to reach 100%, especially after iridium doping, the purity of gold will be greatly reduced. Students who are familiar with the periodic table of chemical elements must know that iridium is very close to gold, and this element has many characteristics similar to gold, such as strong corrosion resistance, so it cannot be seen with the naked eye when mixed with gold. Iridium also has many uses in daily life, such as making pen tips. Iridium is certainly inferior to gold in terms of value
    in fact, gold shops can definitely identify gold. If a gold shop is opened by an individual, he must have this qualification and be able to identify the authenticity of gold. Because if the guest can't answer the relevant questions, the guest will doubt the authenticity of the gold jewelry in the gold shop, and the possibility of shopping in the gold shop is very small. If it is a gold shop opened by a jewelry enterprise, not to mention. General jewelry enterprises attach great importance to the staffing of stores, especially those selling gold and jewelry. The salesperson needs to be more professional. The store manager knows more about gold jewelry, and some gold stores of major brands have higher requirements in this regard. Such brand stores are generally chain stores
    four, there may be many chain stores of this brand in one region. In this case, the headquarters will set up a jewelry appraisal institution, equipped with professional testing instruments and personnel. Therefore, there is no doubt that gold shops can identify gold. After all, not to mention the establishment of gold stores, that is, the establishment of gold stores in other industries. We attach great importance to talent training. Only when service personnel have a certain understanding of their work and have corresponding skills can they give consumers the best experience and carry out their work better
    extended information:
    you can identify the authenticity of the gold necklace yourself. The identification method is as follows:
    I. the seal shall be inspected according to the national standard. The precious metal jewelry shall be marked with the place of origin, manufacturer, material, content and other marks. Those without marks are unqualified products. In case of quality problems, the quality inspection organization can detect and judge according to the identification. Consumers should buy gold jewelry of different brands and different gold contents according to their marks
    II. Sensory inspection method:
    1. Color: all gold is dark yellow, K gold has yellow, red, white and other colors, and imitation gold products are mostly copper alloys with lighter colors
    2. Weight: the gold ratio is 19.3g/cm3, which is much higher than the imitation gold products. For example, a complete gold ring is about 5 grams, while imitation gold products of the same size usually weigh less than 3 grams

  2. The gold in the gold shop is fake. It depends on the credibility of the shop. There is no 100% gold. All gold jewelry is easy to fake. Therefore, it is best to choose famous brands because it is difficult for us to distinguish the purity. Generally speaking, large brands and stores can meet the requirements
    specifically,
    fake gold is not sold in regular gold shops. According to the national standard, the precious metal jewelry must have relevant lettering. In the national standard, the purity of precious metals and the expression method of material imprint, in which gold jewelry is expressed in thousands, or in K number, and used together with alloy, Au or G, for example, gold can be expressed as au990, or it can be directly referred to as gold. 18K gold can represent gold 750, au750, g750, au18k, g18k, etc. The most direct way is to observe the lettering on gold jewelry
    the most direct and effective way to judge the purity of gold is fire assay. However, this method is destructive and can only be used when the gold is recovered. There is a saying that "real gold is not afraid of fire". This is mainly because when the purity of gold reaches a certain level, the color of gold will not change when it is burned. However, 18 karat gold or when burned with fire will appear black. Therefore, it is not recommended to use
    how to distinguish the authenticity of gold:
    1. Identification
    the jewelry mark should include the manufacturer's code, the name and content of precious metal materials
    2. Appearance quality
    mainly refers to the inspection of specific process quality such as the overall shape and processing quality of jewelry
    3. Jewelry weight
    the price of gold jewelry is calculated according to weight and processing cost. The weight of jewelry is one of the important indicators. According to the standard, the unit of measurement of jewelry weight is gram, and the tolerance of single piece of gold jewelry is 0.01g
    4. Gold content
    the gold content in jewelry is an important indicator of its quality. There are many test methods for gold content, which can be divided into chemical analysis method and instrumental analysis method. According to whether the jewelry is damaged in the process of testing, it can be divided into non-destructive testing method and destructive testing method. The daily inspection in the jewelry quality supervision department is generally based on non-destructive testing method, and the density method is combined with X-ray fluorescence spectrometry, electronic probe and other large instruments for analysis. The market supervision and spot check are mainly based on damage detection. Fire assay is the national detection method for determining the gold content in jewelry in China
    5. Look at the color
    according to the different luster and color of gold, you can roughly distinguish pure gold, K gold, real gold and fake gold. That is, the best gold is red yellow, and the fineness is above 95%; The fineness of positive yellow is about 80%; The fineness of cyan and yellow is about 70%; The yellow is slightly gray, and the fineness is about 50%. Therefore, there is a saying "seven green, eight yellow, nine five red, yellow and white with gray and half gold". For jewelry that has been stored for a long time, there is a saying that "copper turns green, silver turns black, and gold never changes color"
    6. Look at the density
    the density of gold is 19.32g/cm3, which is about twice the weight of silver, lead and tin in the same volume. Available formula: the mass (g) of a certain gold jewelry is equal to the volume (cubic centimeter) of a certain gold jewelry. Calculate the density of the measured gold jewelry. If the density is about 19.32g/cm3, it is pure gold or relatively pure gold. Otherwise, it is non pure gold or gold with color difference (this method is not destructive to jewelry)
    7. Bending hardness
    gold has the characteristics of low ductility and hardness, and can be pressed into thin sheets with a thickness of 12.7 microns. When the quality is high, marks can be left with pins or nails. For gold jewelry with more than 97% fineness, wrinkles appear at the bend after two or three times of bending, also known as fish scale lines; About 95% of the gold jewelry of good quality feels hard when it is bent, and the fish scale pattern is not obvious; About 90% of the gold jewelry of good quality is very hard when it is bent, and there is no fish scale pattern; Gold jewelry with more impurities can be broken after two or three times of bending; If it is made of raw gold, the bend is broken, and the section has obvious sand grain shape. When using this method, we should consider the width and thickness of jewelry. The thick and wide jewelry is harder, and the thin and narrow jewelry is softer
    8. Listen to the rhyme and see the elasticity
    when gold jewelry with high fineness is knocked or thrown on the hard ground, it will make a dull low sound of "pop, pop", without rhyme and elasticity. K gold has rhyme, sound and elasticity. The greater the elasticity and the sharper the rhyme, the longer the fineness
    v. use the touchstone to identify the fineness
    use the gold matching plate (the gold medal with the determined fineness) and the tested jewelry to grind on the touchstone, and determine the fineness of the gold jewelry by comparing the colors. This method should be carried out under natural light and fluorescent lamp, not under direct sunlight and incandescent lamp

    10. Grind the gold track of the identified jewelry and the matching brand on the touchstone with acid point
    and test nitric acid on the gold track with glass rod. Because the chemical property of gold element is stable and does not react with acid, the color is unchanged. If it is not gold or pure gold, the golden path will disappear or change. The change law is "three fast and three slow", that is, the low quality disappears quickly and the high quality disappears slowly; Mixed gold disappears quickly and clear gold disappears slowly; The big mixed gold disappears quickly, and the small mixed gold disappears slowly. Depending on the disappearance of the gold channel, the fineness of gold jewelry can be determined by comparing the cards.

  3. Whether there is fake gold in the gold shop depends mainly on the integrity of the merchants. It is not excluded that some unscrupulous businesses, such as the boss who sells fake gold for the sake of profit, or shoddy gold, gilded gold, etc. Generally, regular large-scale well-known gold stores have detailed descriptions and classifications of the composition of gold. Therefore, when buying gold, such precious goods should be purchased from some gold stores with good reputation and reputation. Don't be greedy for small and cheap goods and be careful not to suffer big losses.
