Tips on how to identify the authenticity of silver

I think everyone is familiar with it. In ancient China, we used silver as currency. When it comes to **, the first thing that comes to mind is silver jewelry.

Silver jewelry is common in life, including earrings, rings, necklaces, etc. With ** being sought after by the public, there is a huge amount of dazzling silver jewelry on the market. **Although it is not valuable, it can be true and fake.

How to identify ** is particularly important. **There are three types of identification: marking, color, and weight.

Silver jewelry is usually marked with the English abbreviation of silver. As a modern modern student, the English abbreviation should be familiar, which is "S" or "Sterling". Standard silver seal S925, full silver seal S990.

The English abbreviation of silver, will be hit into silver jewelry. As far as bracelets are concerned, when buying silver bracelets, you can look to see if the inside of the bracelet is engraved with the full abbreviation of small s or silver. If there is, then it should be true.

But there are many fakes in real life, and there will be marks on the inside of the bracelet, so this method cannot be used as a reference. And now many countries don't print banknotes on silver jewelry, so we don't have to worry so much about that. However, there will generally be an appraisal certificate, and silver jewelry will be carried with you when you buy it.

Second, look at the color. Silver and gold are different. Slightly yellowish, i.e. silvery-white, with a softer metallic sheen overall.

But now there are a lot of counterfeit and shoddy products with silver powder paint on the market, and many people will be deceived just by looking at their appearance. In addition, silver is susceptible to oxidation. Over time, its soft silvery-white metallic luster will gradually turn dull yellowish-white.

Then there are two ways to judge, one is the combustion method. If it's true, the color won't change after being roasted over fire. However, if it is fake silver or other inferior products, it will turn black after being roasted by fire.

If you really want to distinguish the authenticity of **, you can try this method, but many people may feel distressed. Finally, there is the weight. The density of silver is grams per cubic centimeter, which is smaller than platinum and gold.

If you weigh it with your hands, it doesn't feel like it's falling. You can use a silver needle to make a mark on the silver and bend it. If you really want to judge by weight, you can keep a small scale at home.

In addition, there are many types of silver now, and the weight of different silver is not the same, so if you want to buy silver jewelry, you must see clearly the density and weight of this silver.

Identification of the authenticity of silver: for the silver with high fineness, the color is white, bright and uniform, and the color of silver with poor fineness gives people a feeling of blue and gray, and the gloss is poor. In addition, silver with high fineness will make a dull popping sound when it falls to the ground, and silver with poor color will make a slightly crisp sound when it falls to the ground.

Silver can be distinguished by burning with fire, after burning silver with a lighter for a period of time, the color of silver with high fineness will not change in any way, and silver with poor color will be blackened and discolored after cauterization.

To distinguish the authenticity of silver, you can look at the color, the color of silver with high fineness is very white, bright and uniform, and the color of silver with color difference will be blue, gray, glossy and dull.

When the silver is dropped to the ground, the silver with high color will make a dull "pop" sound, and the silver will not be elastic, and the silver with different color will make a slightly crisp sound when it falls to the ground.

Look at the color, check the hardness, weigh the weight, and listen to the rhyme.

1. Look at the color.

The higher the purity, the whiter the silver, and the surface of the jewelry looks evenly shiny and polished. If it contains lead, the jewelry will take on a blue-gray color; If copper is contained, the surface of the jewelry will appear rough and the color will not have a sense of moisture.

2. Check the hardness.

**The hardness is lower than copper, and larger than lead and tin, and can be tested in an inconspicuous place where the pin is scratched, if the needle is slippery, it is difficult to leave traces on the surface, it can be judged to be copper jewelry; If it is lead and tin texture, the traces are obvious and prominent; If there are traces of the physical object and it is not obvious, it can be preliminarily judged to be ** jewelry.

3. Weigh the weight.

**Slightly denser than common metals, generally speaking: "light aluminum, heavy silver, not light and not heavy copper." Therefore, the weight can be weighed to make a preliminary judgment on whether it is **. If the jewelry is large in size and light in weight, it can be preliminarily judged that the jewelry belongs to other metals.

4. Listen to the rhyme.

Sterling silver jewelry has a sound on the ground, no elasticity, and the sound is "Porphyry". The lower the color, the lower the sound, and the sharper and higher the voice, the higher and rhyme; If it is copper, its voice is higher and sharper, and the rhyme is rapid and short; If it is made of lead or tin, the sound of throwing the ground is dull, short, and has no elasticity.

Summary. The method of distinguishing the real from the fake** is as follows: (1) Observe the color test:

The higher the purity, the whiter the silver, the delicate and uniform shiny dough, and the polish. (2) Hand weight: **The density is slightly larger than that of common metals, generally speaking

Light aluminum, heavy silver, and copper not light and not heavy. Therefore, a preliminary judgment can be made on whether it is **. (3) Search hardness:

**Hardness is lower than copper, and larger than lead and tin, so use a pin to scratch the surface of the real thing for testing, (4) Listen to the sound: if the jewelry is high fineness**, then there is no rhyme, no elasticity, and the sound is "porphyry". (5) Observe the stubble to set the color:

Cut the ** jewelry, look at the color of the stubble, if the stubble is white and cotton, the surface of the jewelry is smooth and delicate, and the surface color is black and bright after oxidation, and it can be concluded that its fineness is about 98.

The method of distinguishing the true from the fake is as follows: (1) Observe the color test: the higher the purity, the whiter the silver, the delicate and uniform brightness of the dough, and the polish.

2) Hand weight: **The density is slightly larger than that of common metals, generally speaking: "Aluminum is light, silver is heavy, and copper is not light and not heavy."

Therefore, a preliminary judgment can be made on whether it is **. (3) Search hardness: ** hardness is lower than copper, and larger than lead and tin, so use a pin to close the surface of the real thing for testing, (4) Listening:

If the jewelry is high quality**, it will have no rhyme and no elasticity, and the sound is "with fierce porphyry". (5) Observe the color of the stubble bridge: cut off the ** jewelry, look at the color of the stubble, if the stubble is white and cotton, the surface of the jewelry is smooth and delicate, and the surface color is black and bright after oxidation, and its color can be determined to be about 98.

**Ductile rent is simple, is a good thermal conductivity, electrical conductivity of the metal. The first ionization energy electron volt. Chemically stable, it has no effect on water or atmospheric oxygen; Soluble in dilute nitric acid, concentrated sulfuric acid and hydrochloric acid for filial piety, pure buried molten sodium hydroxide.

Crystal structure: The unit cells are cubic unit cells, and each unit cell contains 4 metal atoms. Be cautious.

The methods to identify the authenticity of silver are: through color, bending method, weighing weight, silver smear test, acid-base identification method.

1. Through the color: look at it with the eyes, it looks white, bright and fine, and it is a high-purity silver jewelry, while most of the dull or poor color is fake silver jewelry.

2. Bending method: gently fold the silver jewelry by hand, the silver jewelry that is easy to bend and not easy to break is high, the stiff and almost unfolded color is very low, if it is bent or knocked several times by the hammer, it will crack, this is a silver-plated decoration, those who can not tolerate slight folding and easy to break are fakes.

3. Weight: The density of silver is slightly greater than that of ordinary metals. Generally speaking, aluminum is light, silver is heavy, and copper is not light or heavy, therefore, weighing can make a preliminary judgment on whether it is silver or not, and if the jewelry is large in size and light in weight, it can be preliminarily judged that the jewelry is other metals.

4. Silver smear test: grind the silver jewelry on the touchstone into silver marks (the same as the **test), and smear the silver powder with silver powder (silver powder is a mixture of silver powder and mercury), the color of silver jewelry containing more silver is higher, the color of silver jewelry containing less silver is lower, and the silver jewelry without silver is fake.

5. Acid-base identification method: silver will change color when encountering any acid, and even dissolve, use a glass rod to drop nitric acid or concentrated hydrochloric acid on the file of silver jewelry, and the high color is brown beige (white moss-like silver chloride precipitation), hidden green or slightly green, and the low color is dark green, or even color.

Summary. Hello dear, tips for identifying the authenticity of silver: 1. Color discrimination:

If you look white, shiny, and fine workmanship, and have a mark on the jewelry, it is silver jewelry of high fineness; Poor color, poor color and luster, and dull are mostly fake silver jewelry. 2. Bending method: fold silver jewelry lightly by hand, easy to bend and not easy to break; stiff, barely folded with lower fineness; After bending or cracking with a hammer, it will crack for silver-clad jewelry; Those that can't stand light folding, and are easy to break, are fakes.

3. Throwing method: throw the silver jewelry on the table from top to bottom, and the silver jewelry with high color and low bounce and stable sound is high; Thrown on the table and jumping higher, loud, fake or low-quality silver jewelry. 4. Nitric acid identification method:

Use a glass rod to drop nitric acid on the file of silver jewelry, which is brown beige and slightly green. It is dark green and has a low color of black.

Sterling silver is silver with more than silver content, also called silver. Due to the hardness of silver, the characteristics of silver itself make silver very soft, which is not suitable for the increasingly rich and exaggerated modeling requirements of modern popular jewelry, so it gradually fades out in use. Sterling silver is easy to identify from the appearance, which is the true color of silver.

Summary. Hello, dear. <>

To distinguish the authenticity of silver, it is necessary to check the hardness, look at the stubble, wipe the silver medicine, distinguish the color, and bend the method. First, the higher the color 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 it is opened by hand, there is no elasticity, and its fineness is about 95%; If it is a little elastic, the fineness is about 80% 90%; If the elasticity is large, the fineness is less than 70%.

Second, cut or fold the silver jewelry to see the color of its stubble. If the jewelry is soft, the stubble is thick and soft, slightly reddish, and the color is about 95%; If it is bent hard by hand, the stubble is white and gray, or slightly reddish, and the color is about 90%; If the hardness is large, the stubble is light red, yellow-white or gray, and the color is about 80%; If it is bent and hard, the stubble is reddish, yellowish, earthy yellow and other colors, and the color is about 70%; If the stubble lipstick is black in the middle, or yellow in the black, the color is below 60%.

Third, the silver jewelry of Zheng will be slowed down to grind out the silver channel on the remaining limbs of the touchstone, and use the silver medicine to disturb the song (the silver medicine is mixed with silver powder and mercury into a soft body shape to be smeared on the silver road, the color of the silver medicine is high, and the color of the silver medicine is low, and the silver medicine is not fake. Fourth, it really looks like the surface will be more bright and white, and the workmanship looks fine, it will be printed with the logo of silver jewelry, and the color is also very good, while the fake silver bracelet is poor in color and dull. Fifth, when you gently fold silver jewelry, you find that it is a real silver bracelet that is not easy to bend, and if it is broken or deformed if you fold it lightly, it is a fake.
