How to distinguish real silver from fake silver? How to distinguish real silver from fake silver?

Are you going to buy a silver necklace? I found you detailed information, I hope it will be helpful to you:

How to distinguish the authenticity of silver jewelry.

Color identification method: Observe with the eye, look white, shiny, fine workmanship, and print the store number on the jewelry, for the silver jewelry with high fineness; The color is poor and the matte is mostly fake silver jewelry.

Bending method: lightly fold silver jewelry by hand, which is 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.

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.

Throwing method: Throw the silver jewelry on the table from top to bottom, the bounce is not high, and the sound is stable for the silver jewelry with high fineness; Thrown on the table and jumping higher, the sound is high, and the sound is fake, or silver jewelry of low quality.

There is also a common look to see if it has the sterling silver mark of 925.

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 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.

Weight: **The density is slightly larger than that of common metals, generally speaking: "aluminum is light, silver is heavy, copper is not light and not heavy."

Therefore, the weight can be preliminarily judged 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.

Check the hardness: **The hardness is lower than copper, and larger than lead and tin, and you can use a pin to scratch the inconspicuous place of the jewelry for testing, such as the needle is slippery, and 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.

Listen to the sound rhyme: sterling silver jewelry is loud, 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.

Silver should be black instead of yellow, sterling silver is very white, 925 can be printed, can not be blindly accepted, you can see here.

1. Imprint Silver jewelry should generally be marked with the English abbreviation of silver ("S" or "sterling"). The imprint of standard silver is S925 or 925. The seal of pure silver is S990. However, there are many countries that do not have a mark on silver jewelry.

2. Color Silver jewelry is mostly silvery-white with yellowish tinge, showing a soft metallic luster. Because it is easy to oxidize, the color will turn dark yellowish-white over time.

3. The density of heavy silver is grams of cubic centimeters. Smaller than platinum, **, no drop feel with your hand. The steel needle can be scratched and bent. In this way, it can be distinguished from German silver jewelry with platinum main, karat white gold or imitation silver.

4. Acid test silver will change color or even dissolve when it encounters any acid. If a drop of concentrated hydrochloric acid is placed on the inside of the silver jewelry, a white moss-like silver chloride precipitate is immediately formed. This is not the case with other ***.

5. Sound rhyme The sound of standard silver jewelry is dull after landing, no jumping, no rolling.

Look at the color of the silver, the higher the purity of the silver, the whiter the silver will look, although the silver is easy to oxidize, but after removing the oxide layer, the color of the silver is uniform and shiny. If heavy metals such as lead are mixed in the silver, the silver will turn gray.

The density of silver is greater than that of ordinary metals, so we can weigh it and it will be obvious that silver is heavier than ordinary metals.

The higher the hardness and purity of the silver, it is soft, and it will be bent and deformed with a little force, but it will not break. If the silver with low purity is folded once, it will have lines, and it will break if it is folded a few more times.

Listen to the sound If it is a sterling silver jewelry, it has no elasticity when thrown to the ground, and the sound is "porphyry", the lower the purity, the quieter the sound and the sharper the sound. If it is made of lead or tin, the sound of throwing the ground is dull, short, and has no elasticity.

Look at the imprint: Silver jewelry should generally be marked with the English abbreviation of silver ("s" or "sterling"). The imprint for standard silver is S925 and the imprint for pure silver is S990, but there are many countries that do not print on silver jewelry.

Look at the color: Silver is mostly yellowish silvery-white, with a soft metallic luster. Because it is easy to oxidize, the color will turn dark yellowish-white over time.

There are two ways to judge color. One is the fire method. If it is true**, the silver color will not change after the fire barbecue.

If it is fake**, or inferior, it will turn black after grilling.

Weight: The density of silver is grams of cubic centimeters. Smaller than platinum, **, no drop feel with your hand. The steel needle can be scratched and bent.

Real silver and fake silver are still very good, and in general, real silver will directly turn black when it encounters poisonous things, while fake silver will not react.

1..Measure hardness and softness. Silver is soft, if it can be easily bent or scratched with a hard object, it means that it is genuine, if it is difficult to bend or rub against a hard object will not produce scratches, it may be a fake.

2.Fire method. Calcined at high temperatures, the more the real silverware is burned, the whiter it becomes, and the blackening on the contrary indicates that it is fake.

3.Listen to the sound. If you throw a silverware on a hard ground, if it makes a soft sound, it is real, and if it makes a crisp sound, it is fake.

First of all, you can judge the ** jewelry by the color, it can be burned by fire, if it is a real ** jewelry, the color will not change after the fire. If it is fake or of inferior quality**, the color of the jewelry will turn black after the fire.

Secondly, it is to judge the authenticity of **jewelry by sound, due to the softer texture, if the sound is weak when throwing, it is true**, and if it makes a crisp sound, it is other metals. Then, it can also be judged by weighing, because the specific gravity of ** is, much larger than many other metals.

Finally, it can also be bent**, good quality ** is easy to bend but not easy to break, while lower quality ** bends to feel harder and can also break.

1. Color identification method: Observe with your eyes, look white, shiny, fine workmanship, and print the store number on the jewelry, which is silver jewelry with 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. 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 heavy."

Therefore, the weight can be preliminarily judged whether it is **. If the jewelry is large and lightweight, it can be preliminarily judged that the jewelry is other metals.

The first is to look at the color, the higher the purity, the whiter the silver, the surface of the jewelry looks uniform and shiny, with touch, if it contains lead, the jewelry will appear blue-gray, if it contains copper, the surface of the jewelry will appear rough, and the color has no moisturizing feeling.

Then check the hardness, ** hardness is lower than copper, and larger than lead and tin, you can use a pin to scratch the inconspicuous place of the jewelry for testing, if the needle slips, it is difficult to leave traces, it can be judged as copper jewelry.

If it is lead, tin texture, the traces are obvious and prominent, such as if the physical object leaves traces and does not protrude, it can be preliminarily judged to be ** jewelry.

Then there is the weight, ** density is slightly larger than the common metal, if the jewelry is larger and lighter, it can be preliminarily judged that the jewelry belongs to other metals.

The last is to listen to the sound rhyme, sterling silver jewelry to the ground with sound and no elasticity, the lower the color, the lower the sound, and the higher the sound is sharper and rhyme, if it is copper, its sound is higher and sharp, if it is lead, tin texture, then the sound of throwing the ground is dull and short.

There are three ways to distinguish real silver, fake silver, and the first one, look at the color brightness. The higher the purity of real silver, the higher its brightness, the whiter the color, and the absence of impurities. The second is to weigh the weight.

Real silver, especially sterling silver, has a relatively high density, and it is somewhat pressed in the hand, which is obviously inconsistent with the weight of ordinary metals. The third is to look at the hardness. Real silver, especially sterling silver, is soft in its hardness.

You can bend with a little force, but you won't break. Let's take a closer look.

First, look at the brightness of the color. The higher the purity of real silver, the higher its brightness, and the color of the sterling silver will be whiter and free of impurities. If the jewelry is found to be stained or gray, it is not pure silver, and the silver content is relatively low.

This is the most intuitive way to identify 80% of silver jewelry. Some sterling silver jewelry, because of the long time of wearing, will also have dust, after cleaning, it can restore its original brightness and whiteness, but also can make the right judgment.

Second, weigh the weight. The density of sterling silver is large, so it is manifested in jewelry, as long as you use your hand to know whether it is real silver, the higher the purity of real silver, the more you can feel that it is obviously pressed on the hand, heavier than the general metal. It's also a way to tell if it's real silver.

One hundred grams of sterling silver is very noticeable when held in the hand. Those who know how to do it will know whether it is real silver and how much it contains in their hands. This is also the connoisseur's cognitive practice of sterling silver.

Third, look at the hardness. The hardness of real silver, especially sterling silver, is very soft. It is easy to bend and deform with a little force, but it will not break, which is also a way to judge whether it is sterling silver.

If the silver content is low, or if the content of other metals is too high, it can easily break. Therefore, in sterling silver jewelry, it is recommended to buy silver jewelry with a relatively high number of grams, so that it is not easy to bend. Because the number of grams is too small, it is easy to deform, and no.

1. Listen to sounds.

If the silver jewelry is collided, the sound of real silver is relatively crisp, if it sounds dull and the sound is smaller, it may be that other impurities have been added.

2. Look at the color.

The color of real silver is uniformly white and shiny, if the surface color is different from each other, or even the surface is dark gray, it may be fake silver.

Look at the word 100 in the lower left corner of the RMB, whether there are two color changes: blue and green. The 100 inscription in the lower left corner of the genuine coin uses a special printing technique that changes in blue and green colors as it moves up and down angles.

As long as it is burned black, it is definitely not pure silver, let alone burned to ashes.

According to the purity of the silver, it will be different after the fire, 999 sterling silver is still white after burning red and cooling, and 925 will be black after burning. Why is it black? This is because sterling silver is burned by fire to produce black oxide silver.

Real 925 silver will change color after fire, because the surface layer of silver is extremely easy to oxidize after high temperature, and then it will turn black, but it doesn't matter as long as it is brushed by toothpaste, it will change back to its original color, because the toothpaste contains CaCO3 calcium carbonate and the blackened silver surface undergoes a chemical reaction to generate Cao calcium oxide and water, so that the chemical substance will be "blackened" immediately after entering the water. Therefore, those friends who buy silver jewelry that will change color with fire, please don't worry, because 925 sterling silver will change color when burned with fire.

But the sterling silver will definitely turn white after the fire, the blackened one is definitely not sterling silver, the blackened one does not count, of course, some if the silver plating is very thick, it may not be visible, then it should be rubbed off a little in an inconspicuous place and then burned.

Extended Information: In addition, there are several ways to distinguish real silver:

1. Look at flexibility

The higher the purity of the silver, the better the flexibility, that is, it is easy to bend but will not be broken; Really good texture sterling silver can withstand the hammer and has high plasticity.

2. Look at the logo and color

Each silver jewelry will have a purity mark and a manufacturer's logo, such as S925, S990; S925 is sterling silver and white gold, the color is brighter than the plain silver of S990, while the color of S990 sterling silver is slightly lower and the color is white and yellowish.

3. Listen to the sound

You can toss the silver jewelry lightly to see its bounce and listen to its sound. Sterling silver jewelry will not bounce, the sound is low, if it is silver-plated white copper, the sound is very sharp and loud, it can be judged as fake silver jewelry.
