How to identify the authenticity of a silver bracelet

Question 1: How to tell the authenticity of a silver bracelet? I think (I have been engaged in the processing and manufacturing of silver jewelry for many years 10) that the higher the purity of silver jewelry, the better its flexibility and easy to be oxidized. The oxidation process turns yellow first, and then gradually turns black. At present, 92.5% of the internationally accepted silver content is pure silver. Now there are 925 and 990 silver ornaments on the market, both of which are pure silver. Only the purity of the latter is higher! Note: 1, the color must be white and bright. 2. The sterling silver bracelet must be very soft. 3, weight (generally bracelets are about 20 grams). 4, the safest way is: let the seller cut a small corner or cut a little money to melt. There is no green light during melting, and the color is as white as snow after cooling (hence the name Xueyin). The reasons for blackening may be: 1. It was widely used as a poison testing tool in ancient times. Seeing a lot of ancient costume films, the emperor would insert a silver hairpin in the dish before eating every time, and in ancient times, he would also use a silver needle to test drugs when solving crimes. These are all verified. Then because the human body is constantly metabolizing and eliminating toxins, if the toxins in the body are eliminated and silver is encountered, then silver will turn black. This also reflects that you may not be in good health recently, so you should pay attention to your own examination. 2. I usually do a lot of housework and often come into contact with some strong acids and alkalis. Then, these Ding Dong are easily oxidized with silver ornaments, and their colors will change. Pay special attention to, can't contact with gas, preserved eggs, a contact will change color. Solution: 1 Wash with toothpaste and toothbrush. 2. Wipe the surface with pure cotton cloth. (such as jeans) 3. Go straight to the jewelry store to clean it. If you have any questions, please feel free to communicate!

Question 2: How to identify the authenticity of a silver bracelet?

Teach you to distinguish the authenticity of silver ornaments.

1. If you like, you can draw a silver chain with white wall or white paper to show that most of it is pure silver.

2. Throw the silver one on the table. It sounds boring. It's pure silver, not metal.

3. Generally, regular goods are engraved on jewelry. If it is pure silver, it should be "ag925" or "925". High purity silver jewelry, with yellow in white.

4. Silver forged with copper, brass, white copper, lead, tin, aluminum, etc. Features: copper: purple in appearance, black in stubble and embroidered green. Brass: yellow in appearance, stubble green and embroidered green. White copper: appearance gray, stubble brick gray, green embroidery. Lead: grayish blue, soft, with nail marks. Tin: silvery white, soft, and can be scraped with nails. Aluminum: white gray, soft and light.

If it is allergic skin, you will know whether it is true or not after wearing it for a while.

Look at the color:

The higher the purity, the whiter the silver, and the surface of 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 metals. 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.

Check hardness:

The hardness of silver is lower than that of copper, but higher than that of lead and tin, so it can be tested by marking 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 this poem:

Hit the ground, sterling silver jewelry, no elasticity, the sound is "bam bam". 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.

I hope I can help you. Hope to adopt

Question 3: How to tell the true and false silver bracelets 1) The specific gravity of silver is 10.5, which is much larger than other silver metals or alloys. For example, the specific gravity of lead is only 2.7. 2) The sound judges that silver is soft, and the sound made by throwing it on a hard object is weak, while the sound made by other metals is clear. 3) color judgment The white of other metals is different from silvery white after all, especially after combustion and cooling. After barbecue with fire, if it is real silver, the silver will remain unchanged; If it is fake silver, or a product with poor quality, it will turn black after barbecue. Another method is to drop nitric acid on the surface of silver jewelry. After wiping off the nitric acid, the surface of the jewelry is still silvery white, indicating that the silver content is relatively high, and if the silver content is low, it will be grayish black. 4) Bending method uses both hands to bend, which is high in color, easy to bend and not easy to break. When bending with inferior quality, it feels hard, or can barely bend, and some can't even bend with their fingers. Bend it or knock it with a hammer a few times, and the silver bag will crack. The fake one can't stand bending and is easy to break. The quality of silver jewelry can also be selected from four aspects: ① Look at the welding process of making gold and silver jewelry, whether the welding is clean and tidy, and whether there are cracks in the welding. (2) Brightness requires pure plating color and strong brightness. (3) The electroplating surface should be firm and round. (4) Look at the hook claw. It is required for ornaments not to prick hands, not to scratch clothes, and it is convenient to wear. Six methods for authenticity and color identification of silver ornaments 1) The specific gravity of silver is 10.5, which is much larger than other silver metals or alloys. For example, the specific gravity of lead is only 2.7. 2) The sound judges that silver is soft, and the sound made by throwing it on a hard object is weak, while the sound made by other metals is clear. 3) color judgment The white of other metals is different from silvery white after all, especially after combustion and cooling. After barbecue with fire, if it is real silver, the silver will remain unchanged; If it is fake silver, or a product with poor quality, it will turn black after barbecue. Another method is to drop nitric acid on the surface of silver jewelry. After removing nitric acid, the jewelry surface is still silvery white, indicating that the silver content is quite high. If it is jewelry with low silver content, it will be grayish black. 4) Bending method uses both hands to bend, which is high in color, easy to bend and not easy to break. When bending with inferior quality, it feels hard, or can barely bend, and some can't even bend with their fingers. Bend or knock with a hammer a few times, the silver bag will crack, and the fake one can't stand bending and is easy to break. 5) Look at the stubble test, cut the jewelry in half and fold it in half to see the color. If it is white cotton, the color is about 98%; If the mouth is soft and reddish, the color is about 95%; If the mouth is white gray or reddish, the color is about 95% and the hardness is about 80%; If the mouth is reddish and yellow is gray, the color is about 80%. If lipstick is black and yellow is black, the color is about 60%. 6) Silver medicine (also known as eating silver tiger) After wiping the silver ornaments, grind them into silver grooves on the touchstone and smear them on the silver grooves with silver medicine (silver medicine is a soft object made by mixing silver powder with mercury with purity above 95%). If there is more silver medicine, the fineness will be high, and if there is less silver medicine, it will be low, and the fake one will not hang silver medicine. In addition, the quality of silver jewelry can also be selected from four aspects: ① Look at the welding process of making gold and silver jewelry, whether the welding is clean and tidy, and whether there are cracks in the welding. (2) Brightness requires pure plating color and strong brightness. (3) The electroplating surface should be firm and round. (4) Look at the hook claw. It is required for ornaments not to prick hands, not to scratch clothes, and it is convenient to wear.

Question 4: How to tell the authenticity of a silver bracelet? At least bring a small magnet. It's convenient. You can try it quietly. I once went to buy a silver bracelet, saying that a bracelet made of pure silver can actually attract magnets. Of course, I happened to have something magnetic with me that time. If you buy silver jewelry, use the following method. If you are buying silver ingots, use my bottom to find a way online. Generally, 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. ). The silver jewelry has the following 1 sterling silver seal. 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 Foot silver has the symbol of s990 "or au990" (the latter is a little more), indicating that the silver content of this metal is 99% (quite pure! )。 This sign is mostly used for silver ingots, silver ingots, silver ornaments and other large pieces of silver ornaments. 3 Silver plating, with sl "or fs" steel seal on it, shows that this kind of jewelry is silver plated, and its value need not be said by me! If there is no steel seal, it is probably ordinary metal. The following is the information on the Internet (1). The higher the fineness of 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 smearing test: silver jewelry is ground into a silver tank on the touchstone (the same as gold testing) and smeared on the silver tank with silver medicine (silver medicine is a soft mixture of silver powder and mercury). Silver medicine has a high color, but silver medicine has a low color. Those who don't hang silver medicine are fakes. (4) color discrimination uses eyesight to identify its color and authenticity. 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 bed board, and there is a "poop" sound; Fake or poor quality are light.

Question 5: How to identify the authenticity of the silver bracelet you bought? Good color and elasticity.

When choosing a silver bracelet, you can look at its color first. The higher the purity, the whiter the color, but it is easily oxidized and appears black. Although the oxidized color is a little black, it is very bright. Real silver bracelets are not only bright in color, but also flexible, while fake silver bracelets are much less flexible.

examination

In order to buy a bracelet made of pure silver, you can ask the merchant to cut a small corner or a little silver (with the consent of the merchant, it will not affect the appearance of the bracelet) and test it after melting. If it is pure silver, there will be no green light when it melts, and the color will be as white as snow after cooling.

surface

The surface of the bracelet made of pure silver should be smooth, even and delicate, and the inner wall will not feel scratched.

weight

People often say: "aluminum is light, silver is heavy, and copper is not light or heavy." So we can judge whether it is a silver bracelet by weighing the quality. As mentioned above, if it is large in size and light in weight, it means that it is not made of silver, and it is probably made of other aluminum alloys.

difficulty

Honey, you know what? The hardness of pure silver is lower than copper, but higher than lead and tin. When we choose a silver bracelet, we can try a hard thing on it. If there is slippage and there is no impression on the surface, it can be ruled out that it is silver and may be copper; If the imprint is obvious and has a great sense of prominence, there is a great possibility of lead and tin. The silver bracelet will leave a less obvious trace.

sound

Another way to tell if it is a silver bracelet is to listen to its sound. The sound of silver hitting the floor has no rhythm and will not be bounced. If the bracelet is mixed with copper, the sound will be high and sharp, short and urgent; The sound of lead and tin is dull and short.

skill

Honey, if the silver bracelet is oxidized, you can wipe it with toothpaste and it will return to its original appearance.

Question 6: When buying a silver bracelet, how can you tell the true from the false? If you are buying silver jewelry, use the following methods. If you buy silver ingots (raw silver), use the method I found online at the bottom:

Ordinary precious metal jewelry will have a formal logo, so it is very simple to identify silver jewelry: just look at the inconspicuous places of silver jewelry for steel seals (such as the inside of the ring, the joint of the necklace, the bottom of the pendant, etc.). );

Silver ornaments have the following steel seals.

1: pure silver: there is a sign of "S925" or "Ag925" (the former is a little more), indicating that the metal contains 92.5% silver. 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. Full silver: there is a sign of "S990" or "Au990" (the latter is a little more), which means that the 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.

3. Silver plating: the steel seal with "SL" or "FS" indicates that this kind of jewelry is silver plated, and its value need not be said by me!

4. There is no steel seal: it is probably ordinary metal.

(1) Check the hardness

The higher the fineness of 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 stubble

Cut or fold silver ornaments to see the color of 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 smear 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, but it will be low if it is hung less, and those without silver medicine will be 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) Bending method

Pinch with fingers, soft and elastic, high color, easy to bend, 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) Throwing method

High-quality silver jewelry is relatively heavy, so it doesn't jump high when thrown on the table, and it has the sound of "poop"; 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 also choose the quality from the following four aspects:

(1) Look at 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) Look at the brightness. It requires pure electroplating color and strong brightness.

(3) Look at the veneer. Firm and upright.

(4) look at the claws. It depends on whether the claws have burrs, prick hands and scratch clothes. It is convenient to wear.

Question 7: How to tell the authenticity of a silver bracelet? I see a most professional and safest method that won't damage the silverware. In fact, this method is mainly suitable for cleaning silverware, because no matter what silverware is left for a long time, it will change color and form silver oxide. This method is the principle of reduction reaction. When the oxidized silver is completely reduced, you will have a lot of silver. Never use silver water to wash water or wipe silver cloth. This method is actually equivalent to tearing off your original silver. Of course, it will shine, but it will also peel off the protective layer on the silverware. And your silver has dropped a lot, and it will get darker and darker in the future. Specific operation: aluminum pot (there must be no membrane in it, preferably very old aluminum pot or old aluminum pot) adds water and salt, adds silverware, and starts to boil with high fire. Later, you will find that the silverware is whiter and brighter than when you just bought it! ! Then clean it with clear water, otherwise it will be white and salty. If not, I can only say two things, one is your aluminum pot coating, and the other is that your inner silverware is not silver drops! ! This method is especially suitable for silverware with complicated process or smooth surface, because it can't be cleaned with toothpaste, which will hurt silverware, but this method is completely safe. Give it a try! ! Silver jewelry has the following steel seal 1: pure silver: there is a symbol of "S925" or "Ag925" (the former is a little more), indicating that the metal contains 92.5% silver. 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. Full silver: there is a sign of "S990" or "Au990" (the latter is a little more), which means that the 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. 3. Silver plating: the steel seal with "SL" or "FS" indicates that this kind of jewelry is silver plated, and its value need not be said by me! 4. There is no steel seal: it is probably ordinary metal.

Question 8: How to distinguish between true and false online shopping for sterling silver bracelets Many people use the method of throwing bracelets on the ground to listen to the sound to distinguish between true and false, 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.

At least bring a small magnet. It's convenient. You can try it quietly.

I once went to buy a silver bracelet, saying that a bracelet made of pure silver can actually attract magnets. Of course, I happened to have something magnetic with me that time.

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.

The following is the information on the Internet:

(1), check the hardness.

The higher the fineness of 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 stubble

Cut or fold silver ornaments to see the color of 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, but it will be low if it is hung less, and those without silver medicine will be 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), bending method

Question 9: How to tell the authenticity of silver ornaments? Teach you to distinguish the authenticity of silver ornaments 1. If you like, you can draw a silver chain with white wall or white paper to show that most of it is pure silver. 2. Throw the silver one on the table. It sounds boring. It's pure silver, not metal. 3. Generally, regular goods are engraved on jewelry. If it is pure silver, it should be "ag925" or "925". High purity silver jewelry, with yellow in white. 4. Silver forged with copper, brass, white copper, lead, tin, aluminum, etc. Features: copper: purple in appearance, black in stubble and embroidered green. Brass: yellow in appearance, stubble green and embroidered green. White copper: appearance gray, stubble brick gray, green embroidery. Lead: grayish blue, soft, with nail marks. Tin: silvery white, soft, and can be scraped with nails. Aluminum: white gray, soft and light. If it is allergic skin, you will know whether it is true or not after wearing it for a while. Look at the color: 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. 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 the authenticity of a silver bracelet? 50 points s999 is thousands of feet silver, which means that the higher the silver content, the softer the silver jewelry will be. For example, you can easily break the mouth of this bracelet, which proves that its color is higher. Wear it for a while. The oil on human skin will nourish silver, and the luster of silver will become pale and look soft, not as dazzling as the luster of K gold. The whiter, the more moist. The method of soaking vinegar can also be used. Nitric acid will be used for inspection. Those with high silver content will be beige, and those with low silver content will be green or even black. However, it is recommended not to use these detection methods that will damage jewelry.
