The essence of its own essence is inseparable from two aspects: physical nature, chemical properties, macro perspective and micro perspective. . What are the characteristics of sterling silver and fake sterling silver? The sterling silver characteristics: The higher the purity, the more white the silver, the bright, the fine, the surface is smooth and elegant, the color is moisturizing, the ductility is good, it will not rust, but it can be oxidized and degenerated by the sulfide in the air. Ifged sterling silver characteristics: Forgery of silver is generally made of red copper, brass, white copper, lead, tin, aluminum, etc., each characteristic: red copper: purple and red, black red, green embroidery, green embroidery raw green embroidery Copper: yellow appearance, stubble beans green, raw green embroidery white copper: gray -white, stubble brick gray, raw green embroidery lead quality: gray blue, soft, use quality, use Nails can be drawn trace tin type: silver white, soft, can be used to draw traces with nails aluminum: white gray, soft and light constitution .

(According to the characteristics of the sterling silver and fake sterling silver above, one or two can be distinguished.) 2, the weight of The silver density is slightly larger than the general common metal, about 10.5g/cm³. The aluminum is light, the silver is heavy, and the copper is not light and not heavy, so the weight can make a preliminary judgment on whether it is silver. If the jewelry is large and the weight is light, it can be preliminarily determined that the jewelry is other metals. 3, check hardness The silver hardness is lower than that of copper, and it is larger than that of lead and tin.

locate wholesale fashion jewelry in new york Use a small magnetic block to distinguish the authenticity of the silver. It -made fake molecules usually use relatively low -cost metal nickels to counter gold and silver jewelry through electroplating. Poor quality gold and silver jewelry contains harmful elements such as nickel. Long -term contact with the human body will cause harm to the human body. The surface of fake gold and silver products is nickel -plated, like nickel and magnet, and is a magnetic metal. Cofuing gold and silver products, no matter what materials are made, as long as the surface is nickel-plated, it can be quickly identified by small magnetic blocks (钕 iron boron magnetic steel, commonly known as strong magnetic king, 1-8 mm diameter 1-8 mm). The tip of the gold and silver jewelry is close to the small magnetic block for testing. If the small magnetic block can be sucked, it is prompted that the surface of the gold and silver products is plated with nickel. Pucting data Silver jewelry can be divided into four categories: 925 sterling silver jewelry, Thai silver jewelry, Tibetan silver jewelry, and national silver jewelry. 925 silver jewelry is a silver jewelry made of 92.5%of silver, adding 7.5%copper and zinc alloy. Because the degree of silver with 92.5%of the silver content is most suitable for making silver jewelry, 925 silver is also a recognized silver standard for jewelry for international standards. The price of imported silver is generally 5%-10%more expensive than domestic silver, so the price of foreign brands is higher than domestic silver accessories. It can be imagined that only dozens of yuan of silver jewelry sold in shopping websites or small silver jewelry stores must use the worst silver materials.

Take the silver bracelet of about 60 grams as an example. If you open it with your hand, there is no elasticity, and its color is about 95%; if it is a bit elastic, the color is about 80%~ 90%; %the following. (2) Look at the stubble port This cutting or folding the silver jewelry to see the color of the stubble mouth. If the jewelry is soft, the stubble mouth is thick and soft, with a slight redness, the color is about 95%; if the hands are bent hard, the stubble mouth is white and gray, or slightly reddish, the color is about 90%; Larger, the stubble mouth is light red, yellow and white, or gray, with a color of about 80%; if the bend is hard, the stubble mouth is red, yellow, yellow, etc., and the color is about 70%; Or yellow in the yellow, the color is 60%. rn（3）银药抹试rn将银饰品在试金石上磨出银道（与试黄金相同），用银药（银药是用银粉与水银混合成软体状）在银Apply the road, the color of the silver medicine is high, and the color of the silver medicine is low. (4) Color discrimination The eye force to identify its color and true and false. High color, it looks white, delicate, shiny, and printed on the jewelry with manufacturers, shop numbers and other marks; low color, slightly yellow color, rough workmanship; fake silver jewelry is dark and unclean. (5) Bending method M pinch with your fingers, soft and flexible, easy to be bent and not easy to break; Can't move with your fingers; Baoyin's bending or knocking with a hammer will crack; if you fake it, you can't stand the bend and easily break. (6) Throwing method The high -colored silver jewelry is heavy, and it is not high on the tablet, there is a sound of "click"; The upper bounce was very high, and the sound made is relatively crisp. (7) Nitric acid identification method This dripping nitric acid at the mouth of the silver jewelery with a glass rod, which is high in color with a high color, hidden green or slightly green; the low color is dark green, and even black. In addition, when purchasing silver jewelry, you must select the quality from the following four aspects: (1) Look at welding. Some silver jewelry is welded, so it depends on whether the welding is clean, whether there are fake welding or opening welding. (2) Look at the brightness. It is required to be pure and bright. (3) Look at the plane. Be firm and Zhou Zheng. (4) Look at the hook claws. It depends on whether the hook claws are burrs, whether they are tie, scrape their clothes, and wear it convenient.
The silver jewelry is based on it, and it can be divided into sterling silver, pattern silver and color silver from high to low. According to the processing method, it can be divided into cast silver, creating silver and silver fine work products. The identification of silver jewelry can also adopt methods such as seeing color, test hardness and elasticity, weight, listening rhyme, reagent test and other methods. The silver jewelry has a color of more than 97 %, the epidermis is white and delicate, and the luster is soft and pleasant. The lower color of the skin is blue or gray, and sometimes it is yellow and black.
The silver jewelry itself is very plastic and has a variety of shapes. It is no longer a simple sterling silver jewelry in our impression. It has a lot of fashion elements in styling, variety, and craftsmanship, and the sales of silver jewelry are also increasing year by year.
In addition to sterling silver jewelry, there are also black silver jewelry, Tibetan silver jewelry and color silver jewelry. The temptation of silver jewelry is that it can inlaid gems or imitation gems and other materials, which is more diverse.
The raw materials for silver are cheap, but some manufacturers will add cheaper metals such as cadmium, iron, copper and other cheap metals in silver. Cadmium is harmful to the human body, and it is not allowed to be mixed in jewelry according to regulations. Manufacturers do this mainly to reduce costs and get higher profits. The copper wire is mainly mixed with the middle support frame in the silver lock. The supporting frame in the silver lock according to the national regulations should also be silver. Because the copper silk is hidden in the silver lock, consumers can't see it at all. Only when the jewelry detection is performed, it can see the true face of Lushan. Only when it is waiting for a long time, the copper rust inside is exuded can consumers find it.
The silver jewelry is not valuable, but there are true or false. Although this phenomenon is not common, consumers should master some methods to identify silver jewelry. Consumers can be tested through the physical properties of the silver when they buy. The usually inspection methods are:
In the color of the jewelry: the higher the purity, the white the silver, the surface of the jewelry, the surface of the jewelry looks uniform, there is any polish. If it contains lead, the jewelry will show blue and gray; such as copper, the surface of the jewelry will appear rough, and the color is not moisturized.

Therefore, weight can be used for it. Whether to make a preliminary judgment for silver. If the jewelry is large and the weight is lighter, it can be preliminarily determined that the jewelry is other metals.
The hardness of the hardness is lower than the copper, and the large and tin is large, which can be tested with the inconspicuous places where the jewelry is scratched by large head needles. If the needle is slipped, it is difficult to leave traces on the surface. Copper jewelry jewelry; if it is a lead and tin texture, the traces are obvious and prominent; if there are traces of the physical objects, but not obvious, it can be initially determined as silver jewelry jewelry.
The sound rhyme: Silver jewelry jewelry throwing the ground, no elasticity, the sound is "卟 卟 卟". The lower the color, the lower the sound, and the higher the sound, the higher the rhyme; if it is copper, the sound is higher and sharp, and the rhyme sounds are short and short; , No elasticity.

The formal logo, then the identification of silver jewelry becomes simple: as long as there are no conspicuous places to see the silver jewelry (such as the inside of the ring, the necklace connection, the bottom surface of the pendant, etc.): silver jewelry There are several steel prints 1: Silver: There are signs of "S925" or "AG925" (a little more in the former), which means that the metal silver content is 92.5%. This is the most common symbol, the most common jewelry silver on the market, and it is also a commonly used sign for general silver (don't think about it!). 2: Foot Silver: There are logos of "S990" or "AU990" (the latter a little more), which means that the metal silver content is 99%(quite pure!). This logo is mostly used on large silver jewelry such as silver ingots, silver ingot, and silver setting. 3: Silver, silver -plated: There is a steel print with "SL" or "FS", which shows that this jewelry is silver -plated. 4: There is no steel print: that is likely to be ordinary metals.

free catalogs jewelry making supplies wholesale 925 The difference between Silver Silver Silver Silver Silver (everyone looks at it carefully, which is very helpful for you to buy silver accessories)
925 Silver: refers to the silver containing 92.5%of the silver For sterling silver standards. 100%silver is soft, it cannot be formed during production, it is inconvenient to make silver jewelry, and it is easier to "oxidize". It is commonly known as "color change"
Silver silver: 925 silver -plated external plating (in the industry in the industry (in the industry in the industry (in the industry Called platinum), it can maximize the characteristics of yellowing and turning yellow and black under oxidation or vulcanization. 925 silver with no white gold plated in the industry is "Su Yin", and Su Yin is more likely to oxidize in the air. The best jewelry made by the city 925 silver now found that some silver jewelry used 925 silver, while others used 990 silver. Which is the symbol of pure silver jewelry? Wang Chunsheng, a senior engineer of the National Jewelry Quality Supervision and Inspection Center, explained to reporters that national standards stipulate that 990 silver, 925 silver, and 800 silver can be used for silver jewelry. The silver jewelry now is generally 925 silver. The 925 silver jewelry is a sterling silver with a content of 92.5%, adding 7.5%of the alloy. The addition of the alloy is to improve the luster, brightness and hardness of the silver. And since Tiffini launched the first silver jewelry with a silver content of 92.5%in 1851, 925 silver has become popular, so 925 is currently used as the standard for identification whether it is the standard of sterling silver. After polishing, the 925 silver jewelry shows a very beautiful metallic luster, and it also has a certain hardness. It can inlay gems and make mid -to -high -end jewelry.
990 foot silver, which is 99%of the sterling silver and 1%alloy. Because of its insufficient hardness, it is easy to deform after being made into jewelry. Therefore 990 silver is widely used in industry.
800 silver is 80%of the pure silver with a 20%alloy. Because the lower the purity of the silver, the easier it is to oxidize, so the manufacturer rarely use it to make jewelry.
The silver jewelry that is tested is reassuring
The raw materials of silver are very cheap, only 2 yuan / gram, but some manufacturers will mix cadmium and iron in the silver jewelry , Copper and other cheaper metals. Cadmium is harmful to the human body, and it is not allowed to be mixed in jewelry according to regulations. Wang Gong told this reporter that the manufacturer did this mainly to reduce costs and achieve higher profits. The copper wire is mainly mixed with the middle support frame in the silver lock. The supporting frame in the silver lock according to the national regulations should also be silver. Because the copper silk is hidden in the silver lock, consumers can't see it at all. Only when it is tested, it can see the true face of Lushan. Only when it is waiting for a long time, the copper rust inside is exuded can consumers find it.
The silver jewelry is not valuable, but there are true or false. Although this phenomenon is not common, consumers should master some methods to identify silver jewelry. Wang Gong told reporters that consumers can be tested through the physical properties of the silver when buying. The usually inspection methods are:
In the color: the higher the purity, the white the silver, the surface of the jewelry, the surface of the jewelry looks like the surface of the jewelry looks like Uniform and bright, with color. If it contains lead, the jewelry will show blue and gray; such as copper, the surface of the jewelry will appear rough, and the color is not moisturized.
掂 Weight: Silver density is slightly larger than the general common metal. Generally speaking: "Aluminum light, silver weight, copper is not light and not heavy." Therefore, the weight of the weight can be for it. Preliminary judgments for silver. If the jewelry is large and the weight is lighter, it can be preliminarily determined that the jewelry is other metals.
The hardness of the hardness is lower than the copper, and the large and tin is large, which can be tested with the inconspicuous places where the jewelry is scratched by large head needles. If the needle is slipped, it is difficult to leave traces on the surface. Copper jewelry; if it is a lead and tin texture, the traces are obvious and prominent; if there are traces of the physical objects and not obvious, it can be initially determined as silver accessories.
This sound rhyme: Silver jewelry throwing the ground, no elasticity, the sound is "卟 卟 卟". The lower the color, the lower the sound, and the higher the sound, the higher the rhyme; if it is copper, the sound is higher and sharp, and the rhyme sounds are short and short; , No elasticity.
The Wang Gong also told reporters that it is not ideal to test silver jewelry by the physical properties and experience of silver alone. Only by destroying silver jewelry can use chemical methods can the true and false and disadvantages of the true and false of silver jewelry. However, this is not reached by consumers. In addition to mastering some basic inspection knowledge when buying silver jewelry, consumers should also pay attention to whether the silver jewelry has relevant certificates, certificates, and certificates. Only the silver jewelry detected by the testing agency can buy it with confidence. In addition, the silver content of silver jewelry must be accurately indicated that consumers should check whether there are "S925" on the jewelry when purchasing. "S" is the first letter of Yin's English words, and "925" is a symbol of sterling silver. As long as there is "S925", you can ensure that what you buy is a real sterling silver jewelry. When buying, pay special attention to whether its deduction can be deducted and reliable. When buying the silver chain, you should flatten it to see if the chain ring is knotted or bent. The price of silver jewelry is determined by the content of precious metals, structural design and craftsmanship, so the most important criterion for choosing silver jewelry is to depend on whether you like it. When buying silver jewelry, Secretary -General Sun of the China Baoyu Association also told reporters that at the end of last year, we conducted a test of the jewelry of major shopping malls at the end of last year. The pass rate of silver jewelry basically reached 98%. Therefore, consumers need to go to large shopping malls when buying silver jewelry, even if there is a problem with the jewelry you buy, it can be solved well. Consumers should pay special attention to buy silver jewelry at tourist attractions, because the testing department cannot detect and the industrial and commercial department cannot find it. If you buy bad quality or fake silver jewelry at tourist attractions, the first consumer cannot return to the tourist attraction to return; the second is that most of the jewelry purchased at tourist attractions has no vouchers, so it is not easy to solve the problem Essence Secretary -General Sun finally emphasized that it is best to buy silver jewelry to buy a brand. Some sellers claim that their silver jewelry is ethnic minority, but the inspection is not a sterling silver jewelry. The 925 silver sold on the surface has a large proportion of products to reduce the cost of the bottom.
Thai silver: Thai specialty, the standard is also 925 silver content. The appearance lacks light, pursuing a "ancient" "ancient silver" effect. Compared with the 925 silver -plated silver jewelry, because the popular foundation is not extensive enough, the price is the bottom.
Tibetan silver: Generally does not contain silver components, it is the elegant name of white copper (copper nickel alloys). Traditionally, Tibetan silver is 30%silver plus 70%of copper, but even so traditional craftsmanship The "Tibetan Silver" is not available in the market now, and most of them are replaced by completely white copper.
Pymatic and false silver with false and false silver: Made with other metals to make only one layer of silver to deceive customers. When identifying the jewelry department, because the test is only part of the surface layer, it is easily identified as a thin layer of silver or 925 silver with a thin layer of 999 silver or 925 silver. It is recommended to cut the silver jewelry from the middle to the most reasonable method when the silver jewelry is inspected to detect the innermost part of the middle.
The maintenance of silver jewelry
Stch away from some chemicals, such as substances or perfumes with strong acidity and alkali. If the color change condition, gently wipe with a soft cloth with a toothpaste to be as bright as new. can also use silver cloth, one rubbing like new, anytime, anywhere, convenient and fast, and protective layers, making the silver jewelry do not need to turn dark and darker. Can't dip the water,

free catalogs jewelry making supplies wholesale 925 The difference between Silver Silver Silver Silver Silver (everyone looks at it carefully, which is very helpful for you to buy silver accessories)
925 Silver: refers to the silver containing 92.5%of the silver For sterling silver standards. 100%silver is soft, it cannot be formed during production, it is inconvenient to make silver jewelry, and it is easier to "oxidize". It is commonly known as "color change"
Silver silver: 925 silver -plated external plating (in the industry in the industry (in the industry in the industry (in the industry Called platinum), it can maximize the characteristics of yellowing and turning yellow and black under oxidation or vulcanization. 925 silver with no white gold plated in the industry is "Su Yin", and Su Yin is more likely to oxidize in the air. The best jewelry made by the city 925 silver now found that some silver jewelry used 925 silver, while others used 990 silver. Which is the symbol of pure silver jewelry? Wang Chunsheng, a senior engineer of the National Jewelry Quality Supervision and Inspection Center, explained to reporters that national standards stipulate that 990 silver, 925 silver, and 800 silver can be used for silver jewelry. The silver jewelry now is generally 925 silver. The 925 silver jewelry is a sterling silver with a content of 92.5%, adding 7.5%of the alloy. The addition of the alloy is to improve the luster, brightness and hardness of the silver. And since Tiffini launched the first silver jewelry with a silver content of 92.5%in 1851, 925 silver has become popular, so 925 is currently used as the standard for identification whether it is the standard of sterling silver. After polishing, the 925 silver jewelry shows a very beautiful metallic luster, and it also has a certain hardness. It can inlay gems and make mid -to -high -end jewelry.
990 foot silver, which is 99%of the sterling silver and 1%alloy. Because of its insufficient hardness, it is easy to deform after being made into jewelry. Therefore 990 silver is widely used in industry.
800 silver is 80%of the pure silver with a 20%alloy. Because the lower the purity of the silver, the easier it is to oxidize, so the manufacturer rarely use it to make jewelry.
The silver jewelry that is tested is reassuring
The raw materials of silver are very cheap, only 2 yuan / gram, but some manufacturers will mix cadmium and iron in the silver jewelry , Copper and other cheaper metals. Cadmium is harmful to the human body, and it is not allowed to be mixed in jewelry according to regulations. Wang Gong told this reporter that the manufacturer did this mainly to reduce costs and achieve higher profits. The copper wire is mainly mixed with the middle support frame in the silver lock. The supporting frame in the silver lock according to the national regulations should also be silver. Because the copper silk is hidden in the silver lock, consumers can't see it at all. Only when it is tested, it can see the true face of Lushan. Only when it is waiting for a long time, the copper rust inside is exuded can consumers find it.
The silver jewelry is not valuable, but there are true or false. Although this phenomenon is not common, consumers should master some methods to identify silver jewelry. Wang Gong told reporters that consumers can be tested through the physical properties of the silver when buying. The usually inspection methods are:
In the color: the higher the purity, the white the silver, the surface of the jewelry, the surface of the jewelry looks like the surface of the jewelry looks like Uniform and bright, with color. If it contains lead, the jewelry will show blue and gray; such as copper, the surface of the jewelry will appear rough, and the color is not moisturized.
掂 Weight: Silver density is slightly larger than the general common metal. Generally speaking: "Aluminum light, silver weight, copper is not light and not heavy." Therefore, the weight of the weight can be for it. Preliminary judgments for silver. If the jewelry is large and the weight is lighter, it can be preliminarily determined that the jewelry is other metals.
The hardness of the hardness is lower than the copper, and the large and tin is large, which can be tested with the inconspicuous places where the jewelry is scratched by large head needles. If the needle is slipped, it is difficult to leave traces on the surface. Copper jewelry; if it is a lead and tin texture, the traces are obvious and prominent; if there are traces of the physical objects and not obvious, it can be initially determined as silver accessories.
This sound rhyme: Silver jewelry throwing the ground, no elasticity, the sound is "卟 卟 卟". The lower the color, the lower the sound, and the higher the sound, the higher the rhyme; if it is copper, the sound is higher and sharp, and the rhyme sounds are short and short; , No elasticity.
The Wang Gong also told reporters that it is not ideal to test silver jewelry by the physical properties and experience of silver alone. Only by destroying silver jewelry can use chemical methods can the true and false and disadvantages of the true and false of silver jewelry. However, this is not reached by consumers. In addition to mastering some basic inspection knowledge when buying silver jewelry, consumers should also pay attention to whether the silver jewelry has relevant certificates, certificates, and certificates. Only the silver jewelry detected by the testing agency can buy it with confidence. In addition, the silver content of silver jewelry must be accurately indicated that consumers should check whether there are "S925" on the jewelry when purchasing. "S" is the first letter of Yin's English words, and "925" is a symbol of sterling silver. As long as there is "S925", you can ensure that what you buy is a real sterling silver jewelry. When buying, pay special attention to whether its deduction can be deducted and reliable. When buying the silver chain, you should flatten it to see if the chain ring is knotted or bent. The price of silver jewelry is determined by the content of precious metals, structural design and craftsmanship, so the most important criterion for choosing silver jewelry is to depend on whether you like it. When buying silver jewelry, Secretary -General Sun of the China Baoyu Association also told reporters that at the end of last year, we conducted a test of the jewelry of major shopping malls at the end of last year. The pass rate of silver jewelry basically reached 98%. Therefore, consumers need to go to large shopping malls when buying silver jewelry, even if there is a problem with the jewelry you buy, it can be solved well. Consumers should pay special attention to buy silver jewelry at tourist attractions, because the testing department cannot detect and the industrial and commercial department cannot find it. If you buy bad quality or fake silver jewelry at tourist attractions, the first consumer cannot return to the tourist attraction to return; the second is that most of the jewelry purchased at tourist attractions has no vouchers, so it is not easy to solve the problem Essence Secretary -General Sun finally emphasized that it is best to buy silver jewelry to buy a brand. Some sellers claim that their silver jewelry is ethnic minority, but the inspection is not a sterling silver jewelry. The 925 silver sold on the surface has a large proportion of products to reduce the cost of the bottom.
Thai silver: Thai specialty, the standard is also 925 silver content. The appearance lacks light, pursuing a "ancient" "ancient silver" effect. Compared with the 925 silver -plated silver jewelry, because the popular foundation is not extensive enough, the price is the bottom.
Tibetan silver: Generally does not contain silver components, it is the elegant name of white copper (copper nickel alloys). Traditionally, Tibetan silver is 30%silver plus 70%of copper, but even so traditional craftsmanship The "Tibetan Silver" is not available in the market now, and most of them are replaced by completely white copper.
Pymatic and false silver with false and false silver: Made with other metals to make only one layer of silver to deceive customers. When identifying the jewelry department, because the test is only part of the surface layer, it is easily identified as a thin layer of silver or 925 silver with a thin layer of 999 silver or 925 silver. It is recommended to cut the silver jewelry from the middle to the most reasonable method when the silver jewelry is inspected to detect the innermost part of the middle.
The maintenance of silver jewelry
Stch away from some chemicals, such as substances or perfumes with strong acidity and alkali.
If the color change condition, gently wipe with a soft cloth with a toothpaste to be as bright as new.
can also use silver cloth, one rubbing like new, anytime, anywhere, convenient and fast, and protective layers, making the silver jewelry do not need to turn dark and darker. Can't dip the water,
