Question 2: How to tell whether silver ornaments are real silver? Identification method:
1, chicken mark
According to national regulations, the silver content of silver jewelry must be accurately marked. When consumers buy jewelry, they should check whether there are purity marks S925 and Ag925 (fashionable ones are more common), or S990 and Ag990 (traditional bracelet child lock). If it is not marked, it can basically be concluded that it is ordinary metal.
2. Look at this color
Silver ornaments are mostly yellowish silvery white, which has a touch-up.
Step 3 look at the price
At present, the price of silver in Shanghai Gold Exchange is around one gram of 5 yuan, without adding purchase cost and processing cost. If the price is ridiculously low, it must be impure or fake.
Step 4 consider
The density of silver is slightly higher than that of ordinary metal, which is 10.53g/cm3. It can be preliminarily judged whether it is silver by weighing.
5, check the hardness
The hardness of silver is low, and the silver ornaments are easily bent and broken by hand, indicating that the color is high. Or use a pin to draw in an inconspicuous place, such as the needle slipping, it is difficult to leave traces on the surface, and it can be judged as a copper ornament; If the object has traces but is not obvious, it can be roughly judged as silver jewelry. This method has been widely used since ancient times. It is often seen in costume movies that people who love money like life bite their teeth when they receive silver dollars. Actually, they are testing the hardness.
Step 6 use acid
Silver will change color or even dissolve when it meets any acid. If a drop of concentrated hydrochloric acid is dropped on the inside of silver jewelry, white moss-like silver chloride precipitate will be formed immediately. Other precious metals do not have this phenomenon.
7. Listen to this poem:
The standard silver jewelry sounds dull and inelastic after landing. If it is made of copper, its sound is high and sharp, and its rhyme is short and short;
It is no problem to distinguish the authenticity of silver ornaments by using the above methods comprehensively. If the counterfeiter can achieve perfection, then his cost is much higher than the real sterling silver, and there will be no profit. If consumers want to know the exact content of silver jewelry, they can only go to the jewelry or precious metal testing center for testing, and the cost ranges from 30 to 100.
Precautions:
Pay special attention to whether the fasteners can be fastened securely when purchasing. When buying a silver chain, lay it flat and see if the links are kinked or bent.
Silver jewelry is generally divided into electroplating and electroless plating:
There is electroplating: that is, the inner layer of pure silver, surface electroplating, mostly platinum plating; Electroplating makes its surface brighter than pure silver, with good reflective effect and is not easy to be oxidized. This process is often used in fashion products.
Electroless plating: Although it retains the natural and simple luster of pure silver, it is easy to turn black or yellow due to vulcanization (sulfur dioxide in the air reacts with silver to form a layer of silver sulfide on the silver ornaments, which is the same as the apple will slowly turn black after being cut). It needs to be maintained with silver cloth to restore luster.
Question 3: How can we identify the authenticity of silver jewelry? The easiest way to choose silver jewelry in a silver shop:
1。 Look at the color: anyone who says 925 silver will not be too bright, and the reflection will be black (if he says silver is plated with platinum), then you should be careful. Because the silver content of most platinum plating is less than 92.5%
If it's 9999 silver (this kind of silver jewelry is not common, you have to go to a very professional silver shop, not counting pirate ships), then it's simple. The first color is yellow, and the reflection is very soft.
2. Look at the price: At present, most silver ornaments are 60% off, but this is not the point. At present, the purchase price of silver is about 5-8 yuan per gram (the silver content will be different at different prices), plus 20% of the process fee. If calculated by gram, the price is too low, which is definitely a problem.
3. chemical method: (but this trick should not be used by the store) bring a boiled egg and touch the silver ornaments with the clear or yellow of the egg anywhere. It only takes a few seconds to turn black!
4. Handmade: 9999 silver is the best, it can be folded in half and then bent back, with good ductility. 925 is prone to problems and can be corrected by hand, but it will be more severe, which may slightly affect the shape, and the fake one will be broken.
PS: What kind of Miao silver and Tibetan silver can be played with and sold only by craftsmanship, because the silver content of these two kinds of silver is extremely low, and they can't even be called "silver ornaments". If you are allergic, it is best to wear less, which is easy to induce allergies. (I am) At present, most of the silver ornaments on the market are 925 silver (S925), because this kind of silver is hard and does not like to be broken, which can meet the requirements of jewelry silver. Silver with too high purity is soft and easily deformed, so it is not commonly used.
Question 4: How to identify sterling silver jewelry? Silver ornaments can be divided into pure silver, broken silver and colored silver according to their fineness. According to the processing method, it can be divided into silver casting, silver making and silver fine products. The identification of silver ornaments can also adopt the methods of looking at the color, testing the hardness and elasticity, weighing, listening to the melody, testing the reagents and so on. The fineness of silver jewelry is above 97%, the skin is white and delicate, and the luster is soft and pleasing to the eye; The skin color of the weak is bluish white or gray, sometimes it is yellow, black and other variegated colors, and the color is dull. Silver jewelry itself has strong plasticity and changeable shape, and it is no longer the pure silver jewelry in our impression. It has many fashion elements in shape, variety and technology, and the sales of silver jewelry are also rising year by year. Besides sterling silver jewelry, there are black silver jewelry, Tibetan silver jewelry and colored silver jewelry. The attraction of silver jewelry is that it can be inlaid with gems or imitation gems and other materials, which is more diverse. Although the raw material of silver is very cheap, some manufacturers will mix cheaper metals such as cadmium, iron and copper into silver ornaments. Cadmium is harmful to human body and is not allowed to be mixed in jewelry according to regulations. Manufacturers do this mainly to reduce costs and obtain higher profits. Copper wires are mainly mixed in silver locks to make intermediate support frames. According to national regulations, the support frame in the silver lock should also be silver. Because the copper wire is hidden in the silver lock, consumers can't see it at all. Jewelry can only be destroyed after inspection, and its true colors can be seen. Only after a long time, the copper rust inside oozes out, and consumers can find it. Although silver jewelry is not expensive, it is difficult to distinguish between true and false. Although this phenomenon is not common, consumers should master some methods to identify silver jewelry. Consumers can test the physical properties of silver at the time of purchase. Common testing methods are: look at the color of jewelry: the higher the purity, the whiter the silver, and the jewelry surface looks even, shiny and polished. If it contains lead, the jewelry will appear bluish gray; If it contains copper, the surface of jewelry will be rough and the color will not be moist. Jewelry weight: the density of silver is slightly higher than that of ordinary metal. Generally speaking, "aluminum is light, silver is heavy, and copper is not light or heavy." Therefore, it can be preliminarily judged whether it is silver by weighing. If the jewelry is large and light, it can be preliminarily judged that the jewelry belongs to other metals. Hardness inspection: the hardness of silver is lower than that of copper, but higher than that of lead and tin. It can be detected by marking the jewelry in an inconspicuous place with a pin. If the needle slips, it is difficult to leave traces on the surface, which can be judged as copper jewelry; If it is made of lead and tin, the trace is obvious; If the object has traces but is not obvious, it can be preliminarily judged as silver jewelry. Listen to the rhyme: hitting the floor, a piece of sterling silver jewelry, no elasticity, the voice is "boo boo boo". The lower the color, the lower the sound, and the sharper and higher the rhyming sound; If it is made of copper, its sound is high and sharp, and its rhyme is short and short; If it is made of lead and tin, the sound of falling to the ground is dull, short and inelastic. It is not an ideal method to test silver ornaments only by their physical properties and experience. Only by destroying the silver ornaments can the authenticity of the silver ornaments be tested by chemical methods. However, this is beyond the power of consumers. When buying silver jewelry, consumers should not only master some basic inspection knowledge, but also pay attention to whether silver jewelry has relevant certificates, certificates and certificates. Only silver jewelry that has been tested by testing institutions can be purchased with confidence. In addition, the silver content of silver jewelry must be accurately marked, and consumers should check whether there is the word "925" on the jewelry when buying. "925" is a symbol of pure silver. As long as you have "925", you can guarantee that you are buying genuine sterling silver jewelry. Pay special attention to whether its fasteners can be fastened and secure when purchasing. When buying silver chain jewelry, put it flat and see if the links are kinked or bent. The price of silver ornaments is determined according to the content of precious metals, structural design and craftsman's skills, so the most important criterion for choosing silver ornaments is whether you like to add: 925 Silver Jewelry Identification Tips About 925 Silver Jewelry is an indispensable combination metal in K gold jewelry, but as a silver-based jewelry, it is mainly a kind of "standard silver" with high purity. The hardness of silver is 2.7. In order to improve its hardness and obtain the best molding effect, it is necessary to add 7.5% copper to silver when making jewelry. This alloy containing 92.5% silver and 7.5% copper is called standard silver internationally. Also known as the pound in Britain. In addition, there are enough silver ornaments with a silver content of 99% on the market. 925 silver is the international standard silver for making silver ornaments. It is different from 9.999 silver because ... >>
Question 5: How to identify silver jewelry ~ Generally speaking, the cost of silver jewelry is not high, so there will be no absolute fake silver jewelry, and the authenticity lies in the difference in purity. To identify the purity and quality of silver jewelry, you can refer to the following points: Look at the color: the higher the purity, the whiter the silver, and the surface of the jewelry looks even, shiny and polished. If it contains lead, the jewelry will appear bluish gray; If it contains copper, the surface of jewelry will be rough and the color will not be moist. Weighing: The density of silver is slightly higher than that of ordinary metal. Generally speaking, "aluminum is light, silver is heavy, and copper is not light or heavy." Therefore, it can be preliminarily judged whether it is silver by weighing. If the jewelry is large and light, it can be preliminarily judged that the jewelry belongs to other metals. Hardness inspection: the hardness of silver is lower than that of copper, but higher than that of lead and tin. It can be detected by marking the jewelry in an inconspicuous place with a pin. If the needle slips, it is difficult to leave traces on the surface, which can be judged as copper jewelry; If it is made of lead and tin, the trace is obvious; If the object has traces but is not obvious, it can be preliminarily judged as silver jewelry. Listen to the rhyme: hitting the floor, sterling silver ornaments, no elasticity, the voice is "boo boo boo". The lower the color, the lower the sound, and the sharper and higher the rhyming sound; If it is made of copper, its sound is high and sharp, and its rhyme is short and short; If it is made of lead and tin, the sound of falling to the ground is dull, short and inelastic.

Question 6: How to distinguish the authenticity of silver ornaments Many people use the method of throwing their bracelets on the ground to listen to the sound to distinguish the authenticity, which is a big misunderstanding. Generally, the imitations of silver are mainly copper and white copper. The color of white copper is easy to be confused with the real one, but it is too hard and there is a metallic sound when it falls. Copper is soft and sounds like silver when it falls. As long as it is wrapped in silver, it is more difficult to identify, so there are many imitations of copper. Please don't believe the sound of landing, you will be fooled.
If you buy silver jewelry, use the following method. If you buy silver ingots (raw silver), use my bottom to find a way online: ordinary precious metal jewelry will have a formal logo, so it will be very simple to identify silver jewelry: just look at the inconspicuous places of silver jewelry (such as the inside of the ring, the joint of the necklace, the bottom of the pendant, etc.) to see if there is a steel seal. ): Silver ornaments have the following steel seals.
1, pure silver, marked with "S925" or "Ag925" (the former is a little more), indicating that the silver content of this metal is 92.5%. This is the most common symbol, the most common jewelry silver on the market, and it is also generally sold (don't get me wrong! ) common signs.
2. All silver, marked with "S990" or "Au990" (the latter is a little more), indicating that this metal contains 99% silver (quite pure! )。 This sign is mostly used in silver ingots, silver ingots, silver ornaments and other large pieces of silver ornaments. What do you mean by s999 silver and Ag999 silver? Thousands of feet Yintong often has two signs; One logo is Ag999 with the same name, and the other is s999. 3, silver plating, silver plating, with "SL" or "FS" steel seal, indicating that this kind of jewelry is silver-plated, and its value need not be said by me!
4. If there is no steel seal, it is probably ordinary metal.
Knowledge 1:
Silver related knowledge
(1), check the hardness. The higher the fineness of the silver jewelry, the softer the texture and the whiter and smoother the surface. Take a silver bracelet of about 60 grams as an example. If you pull it by hand, it will open and have no elasticity, and the color is about 95%. If it is a little elastic, the color is about 80%-90%; If the elasticity is large, the fineness is below 70%. (2) Look at the stubble scissors or silver ornaments, and look at the color of the stubble. If the jewelry is soft, the stubble is thick and soft, slightly red, and the color is about 95%; If you bend hard by hand, the stubble is white gray or reddish, and the color is about 90%; If the hardness is large, the stubble is reddish, yellowish white or light gray, and the color is about 80%; If it is a hard bend, the stubble is reddish, yellowish, khaki and other colors, and the color is about 70%; If the stubble is red, medium and black or yellow, the color is below 60%.
(3), silver medicine wiping test
Grind the silver ornaments on the touchstone (the same as gold inspection) and coat them with silver medicine (silver medicine is a soft mixture of silver powder and mercury), so that the color of silver medicine will be high if it is hung more, and the color will be low if it is hung less. Those without silver medicine are fakes. (4) color identification method
Distinguish its color and authenticity with vision. High color, white, delicate, shiny, jewelry printed with manufacturers, store numbers and other signs; Low color, yellow color and rough workmanship; The fake silver jewelry is dark and not bright. (5) the bending method is held by fingers, which is soft and elastic with high color, easy to bend and not easy to break; The quality of the bend is hard, or barely moving, and some can't even move their fingers; The bending of silver plating or a few strokes with a hammer will crack; Fake ones can't stand bending and break easily. (6) Silver ornaments with high fineness by throwing method are heavier, so they can't jump high when thrown on the table, and there is a "poop" sound; Fake or poor quality is relatively light, and it bounces high when thrown on the table, making a crisp sound.
(7), nitric acid identification method
Drop nitric acid on the file mouth of silver jewelry with a glass rod, and the dark color is brown rice, dark green or light green; Light colors are dark green or even black. In addition, when buying silver jewelry, we should choose the quality from the following four aspects: (1) and welding. Some silver ornaments are welded, so it depends on whether the welding is clean and tidy, whether there is false welding or open welding.
(2) Looking at brightness, it is required that the plating color is pure and the brightness is strong.
(3) Look at the veneer, which should be firm and geometric.
(4) Look at the claws to see if there are burrs on the claws, if there are any cuts on the clothes, and if it is convenient to wear. Knowledge 2: Buy some.
1. First of all, the silverware you want to buy must have a font size, not a nameless one. Then you can see if the silverware you bought has the name of their shop. If not, ask him to do it. If he doesn't do it for various reasons, please don't buy it. This must be a shop.
Question 7: How to quickly distinguish the authenticity of silver ornaments? When buying silver ornaments, just look at whether there are steel seals in inconspicuous places of silver ornaments (such as the inside of rings, the joints of necklaces, the bottom of pendants, etc.). ). Hint: 1) stamp. Silver ornaments are generally stamped with the English abbreviation of silver ("S" or "Sterling"). The mark of standard silver is S925. The imprint of foot silver is S990. But there are also many countries that don't print paper money on silver ornaments. 2) color. Silver ornaments are mostly yellowish silvery white with a soft metallic luster. Due to easy oxidation, the color will turn dark yellow and white after a long time. 3) Weighing. The density of silver is10.53g/cm3. Smaller than platinum and gold, it won't fall off by hand. Steel needles can be marked or bent. In this way, it can be distinguished from platinum jewelry, K gold jewelry or imitation silver jewelry. 4) Acidity test. Silver will change color or even dissolve when it meets any acid. If a drop of concentrated hydrochloric acid is dropped on the inside of silver jewelry, white moss-like silver chloride precipitate will be formed immediately. Other precious metals do not have this phenomenon. 5) Phonology. Standard silver jewelry has a dull sound after landing, and does not bounce or roll. After you determine that your favorite silver jewelry is made of real 925 material, how can you tell its quality? There are two other ways for you to choose: 1, color discrimination method: the silver jewelry with high color is white, shiny and fine in workmanship, and the store number is printed on the jewelry; Most silver ornaments with poor color and dull color are of poor quality. 2, bending method: gently fold the silver jewelry by hand, easy to bend and not easy to break, high color; Stiff, barely folded colors are lower; Silver-plated jewelry will crack if it is bent or knocked a few times with a hammer; Those that can't stand a light discount and are easy to break are fakes.
Question 8: How to distinguish between true and false silver jewelry Although it is much cheaper than other precious metals, there are still some silver jewelry with uneven quality everywhere in the market, which makes it difficult to distinguish between true and false. ? Here, I provide some simple ways for consumers to distinguish between true and false silver ornaments. 1. First of all, the silverware you want to buy must have a font size, not a nameless one. This kind of shop is suitable for creating its own brand on the online shop. For example, various brand products of Shun An Deyu have their own unique signs. Many online stores make silver ornaments by molding, so they don't name the manufacturers. Shops that hand-build their own brands on Taobao generally have store logos, while ordinary molded shops have no store logos. Brand silverware in physical stores is also marked, but most stores have no store logo, mostly a logo with silver content. Moreover, in shopping malls, merchants will not ask for store names without processing conditions, so many online stores created for you have no processing conditions, so the requirements for store names are rarely met. Please ask the store to burn the silverware you want to buy red on the spot. If it is pure white, it may be true. Why can't you promise? Because many fake silverware are covered with other metals, if the thickness of the bag is relatively thick, it will be invisible at once. Large shopping malls will not provide this service. After all, if you don't buy a burnt bracelet, who will you sell it to? Besides, we can't go shopping with a torch on our backs, can we? As for the limitations of online stores, even if the owner posted a burnt bracelet picture, it can't prove that what you bought must be silver. 3. If you are still not sure whether it is burnt, especially if it is silvered, you can file the bottom edge with a file. It doesn't usually get in your way. Just file it with sandpaper, then burn it again, clean it and polish it. It won't make any difference. This is only suitable after you have bought it. If you haven't bought it yet, will the people in the mall let you move? The same is true for online stores. Even if the store is on the map, it can't prove that you bought silver. This article 2.3 is only applicable to small workshops. There are many gold and silver processing shops in Yunnan, but one thing is that the silver ornaments in these small workshops are impure, that is, 92.5% silver and 90% silver are melted into silver water. Can you tell? What's more, it can't be turned into silver water, and it can only be simply burned. Can only simply judge whether it is silver-plated silver jewelry. 4. Misunderstanding of distinguishing between true and false silverware: Many people use the method of throwing bracelets on the ground to listen to the sound to distinguish between true and false silverware, which is a big misunderstanding. Generally, the imitations of silver are mainly copper and white copper. The color of white copper is easy to be confused with the real one, but it is too hard and there is a metallic sound when it falls. Copper is soft and sounds like silver when it falls. As long as it is wrapped in silver, it is more difficult to identify, so there are many imitations of copper. Please don't believe the sound of landing, you will be fooled! It's true. After all, the human ear is not a noise meter, and different people feel different about the same sound. It's like saying that 70-degree water is a little hot for me, and so is others. Therefore, it is suggested that the way of placing silverware out of order, such as weighing, looking at colors and licking with your tongue, is not reliable. Look at the color. Most silverware is coated now. The color you see is actually the color of the coating. Can you tell if it is silver by looking at the color of the coating? Secondly, the gloss of 99 silver and 925 silver without electroplating is the same when they leave the factory. The naked eye cannot judge the tiny 6.5% metallic color. Personal wearing experience, my ring is plated with 925 silver, and the bracelet is not plated with 99 silver. After I wore it for 2 years, the coating of the ring was completely the same color as 99 silver, but the difference was that 99 silver was softer and 925 silver was harder.
Question 9: How to identify silver ornaments in a simple way? Generally speaking, the cost of silver jewelry is not high, so there will be no absolute fake silver jewelry, and the authenticity lies in the difference in purity. To identify the purity and quality of silver jewelry, you can refer to the following points: Look at the color: the higher the purity, the whiter the silver, and the surface of the jewelry looks even, shiny and polished. If it contains lead, the jewelry will appear bluish gray; If it contains copper, the surface of jewelry will be rough and the color will not be moist. Weighing: The density of silver is slightly higher than that of ordinary metal. Generally speaking, "aluminum is light, silver is heavy, and copper is not light or heavy." Therefore, it can be preliminarily judged whether it is silver by weighing. If the jewelry is large and light, it can be preliminarily judged that the jewelry belongs to other metals. Hardness inspection: the hardness of silver is lower than that of copper, but higher than that of lead and tin. It can be detected by marking the jewelry in an inconspicuous place with a pin. If the needle slips, it is difficult to leave traces on the surface, which can be judged as copper jewelry; If it is made of lead and tin, the trace is obvious; If the object has traces but is not obvious, it can be preliminarily judged as silver jewelry. Listen to the rhyme: hitting the floor, sterling silver ornaments, no elasticity, the voice is "boo boo boo". The lower the color, the lower the sound, and the sharper and higher the rhyming sound; If it is made of copper, its sound is high and sharp, and its rhyme is short and short; If it is made of lead and tin, the sound of falling to the ground is dull, short and inelastic.
Question 10: How to identify sterling silver jewelry? Silver is an indispensable combination metal in K-gold jewelry, but as a jewelry dominated by silver, it is mainly a kind of "standard silver" with high purity. The hardness of silver is 2.7. In order to improve its hardness and obtain the best molding effect, it is necessary to add 7.5% copper to silver when making jewelry. This alloy containing 92.5% silver and 7.5% copper is called standard silver internationally. Also known as the pound in Britain. In addition, there are enough silver ornaments with a silver content of 99% on the market. 925 silver is the international standard silver for making silver ornaments. It is different from 9.999 silver, because 9.999 silver has a high purity and is very soft, so it is difficult to make complicated and diverse ornaments, while 925 silver can. In fact, the silver content of 925 silver jewelry is not 100%, because 7.5% alloy is added to pure silver, which improves the luster, brightness and hardness of silver. Only use our colorful silver jewelry today * _ * silver identification 1) to mark. Silver ornaments are generally stamped with the English abbreviation of silver ("S" or "Sterling"). The mark of standard silver is S925. The imprint of foot silver is S990. But there are also many countries that don't print paper money on silver ornaments. 2) color.
