When using toothpaste to distinguish the authenticity of silver jewelry, you need to evenly apply some toothpaste on the surface of the silver jewelry, and then use a soft-bristled toothbrush to dip a small amount of water and repeatedly brush the part of the silver jewelry to apply the toothpaste, if the silver jewelry can show a bright luster, it means that the silver jewelry is real, otherwise the fake silver jewelry will show a dull color.
In addition to being used to distinguish the authenticity of silver jewelry, toothpaste can also be used to clean silver jewelry. The toothpaste contains a small amount of friction particles, and when the toothpaste is applied to the silver jewelry, and then the part of the silver jewelry that is applied repeatedly with a soft-bristled toothbrush can easily remove the oxide on the surface of the silver jewelry, and the silver jewelry can also restore its original luster.
Precautions for silver jewelry maintenance
1. Don't swim in the water: Silver bracelets will change with the substances in the seawater, which will make silver jewelry black, and wearing jewelry into the sea, even if it does not change, it will be easy to lose.
2. Don't touch cosmetics: Don't wear silver bracelets for makeup, cosmetics, perfumes, gel water will have a bad reaction with silver bracelets, if this is the case for a long time, the discoloration or oxidation of silver bracelets is normal.

1. Look at the imprint.
Silver jewellery should generally be marked with the abbreviation "S" or "sterling" for silver. The standard silver imprint is S925, or the imprint. The seal of pure silver is S990.
However, there are many countries that do not have a mark on silver jewelry. Or is the imprint. There is the mark of the thousand-foot silver or S999, too.
2. Check the color.
Silver jewelry is mostly silvery-white with a slight yellowish tinge, with a soft metallic luster. Because it is easy to oxidize, the color will turn dark yellowish-white over time.
3. Weigh the 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. This method can be distinguished from German silver jewellery in platinum, karat white gold or imitation silver.
4. 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.
5. Listen to the rhyme.
Sterling silver jewelry is loud and non-elastic. 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.

1. Look at the color.
The higher the purity of silver jewelry, the whiter the silver, and the surface looks uniform and shiny, with polish. If it contains lead, the jewelry will take on a blue-gray color; If it contains copper, the surface of the jewelry will appear rough and the color will not have a sense of moisture.
2. Weigh the weight.
The density of ** is slightly larger than that of common metals, light aluminum, heavy silver, and copper is not light and heavy, so 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.
3. 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.
4. Listen to the rhyme.
Sterling silver jewelry is loud, no elasticity, the lower its fineness, the lower the sound, and the sharper the sound 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.

The easiest way to distinguish the authenticity of silver jewelry: specific gravity judgment, sound judgment, color judgment, bending method, and stubble test.
1. Specific gravity judgment:
**The specific gravity is much greater than that of other metals or alloys, such as lead, which is only .
2. Sound judgment:
Soft, the sound of falling on a hard object is weak, while the sound of other metals is crisp.
3. Color judgment:
After the fire is grilled, if it is true, the silver color will not change; If it is fake**, or the color is inferior, it will turn black after grilling. Another method is to use nitric acid to drop on the surface of silver jewelry, after wiping nitric acid, the surface of the jewelry is still silvery-white, which indicates that the silver content is quite high, if the silver content is low, it will be gray-black.
4. Bending method:
Bend with both hands, the color is high, easy to bend and not easy to break, the quality of the bending is harder, or barely folded, there are Sakura Ji Xun can not even be folded with fingers, the silver-clad will crack after bending or knocking with a hammer a few times, and the fake one will not be bent by the ridge, easy to break.
5. Look at the stubble test:
Cut the jewelry in half horizontally and fold it to see the color. If the mouth is white and cotton, the color is about 98, if the mouth is thick and soft, slightly reddish, the color is about 95.
Bend hard by hand, if the mouth is white and gray, or slightly reddish, the color is about 95, the hardness is larger, if the mouth is light and red, yellow with gray, the color is about 80, the bend is hard, if the mouth is reddish, yellowish, yellowish and other colors, the color is about 70; If the lipstick is black in the middle and black in the yellow, the color is around 60.

The easiest way to distinguish the authenticity of silver jewelry: look at the color, look at the hardness, and listen to the sound.
1. Look at the color.
The higher the silver content of a silver bracelet, the better the fineness will be. The silver jewelry is plain and elegant, and it will not be particularly bright. The higher the color of the silver bracelet, the more rustic it is, and the more elegant the color.
If it contains other metal additives, it will look particularly bright. So by the color, we can also judge the authenticity of the silver bracelet.
2. Look at the hardness.
The hardness of silver bracelets is relatively low, after all, silver is a soft metal, especially easy to bend and deform. When we choose a silver bracelet, we can judge the hardness of the silver bracelet by the hardness. If the silver content is relatively high, it can be bent with a little force, indicating that it is a real silver bracelet.
However, if the silver content is relatively low, the hardness will be relatively high and it will not be easy to bend.
3. Listen to the sound.
If you feel that the way to look at the hardness is a bit risky, then we can also choose the method of listening to the sound to judge the authenticity of the silver bracelet. The sound of sterling silver is relatively rich and stable, and there will be no sharp and harsh feeling. So when we throw the bracelet upwards naturally, we can judge the authenticity of the silver bracelet by the sound it makes.
How to care for silver jewelry
1. Clean regularly.
Maintaining silverware requires regular cleaning, as silverware can accumulate a lot of dust, dirt and other impurities on the surface after long-term storage or wear, and regular cleaning helps to maintain the aesthetics of silverware.
2. Avoid bumps.
In addition, the maintenance of silverware also needs to avoid bumps and impacts, silver is a relatively soft metal, so it is necessary to avoid collisions with silverware and other hard objects, otherwise it is easy to cause deformation of silverware.
3. Avoid chemical components.
The common cosmetics, perfumes, detergents and other products in life all contain certain chemical components, and when silverware is often in contact with such products, the chemical components will cause corrosion on the surface of silverware.

<>1. It can be burned with fire. Real silver was not afraid of fire earlier, and after the silver jewelry was burned by fire, the surface was still bright and clean as new, and there was no change. If the surface gradually turns black after being burned by fire, this silver jewelry is likely to have a problem with the material, and you need to be vigilant.
2. You can look at the hardness. The texture of real silver is soft and bent with a little force, but it has the characteristics of being easy to bend and not easy to break, and it will not break easily. The texture of fake silver jewelry is often relatively hard and not easy to break, but it is easy to break if you use too much force.
3. You can listen to the sound. Lift the silver jewelry up a little above the ground and let it go to free fall, listening carefully for the sound of the silver jewelry hitting the ground. The sound of real silver jewelry is weak and dull, and there is no bullet to hold the force, while the sound of fake silver jewelry is mostly sharp and loud, and it has elasticity.

<>1. Look at the color. The higher the purity of the silver jewelry, the whiter the color, and the surface of the jewelry looks shiny and evenly glossed. If the silver jewelry is dark white and the luster is not bright, it belongs to the silver with low purity, the purity of S925, if the silver jewelry is yellowish and white, the surface is rough and there is no gloss, it belongs to fake silver jewelry, which contains copper, or more tin!
2. Look at the hardness. Regardless of the purity of gold and silver, the softer and easier it is to bend, why in ancient times it was necessary to bite gold or silver with teeth, because if it was a real tooth, it would be a little imprint. So you can take a steel needle and scratch it in the inconspicuous place of the silver jewelry, if there is no mark and the surface is smooth, it is fake, if there is a mark and the feeling of squeezing, it means that it is true.
3. Listen to the sound. Dropping silver jewelry from top to bottom on the floor, making a "pop-pop" sound, and not bouncing high, indicates that it is real. If the silver jewelry falls down from the shed and makes a "dangdang" sound on the floor, and the bounce is higher, it is of lower purity or fake silver!
4. Acid test. Silver will change color and even dissolve when it encounters any reed and acid. If a drop of concentrated hydrochloric acid is dropped on the inside of silver jewelry, a white moss-like silver chloride precipitate will be immediately generated, while other *** do not.
Use a glass rod to drop nitric acid on the file of silver jewelry, which is brown rice, stable green or Hui green with higher fineness; It is dark green or even black, and the color is lower without foam or foam at the file. The silver jewelry is ground out of the silver channel on the touchstone, and the silver medicine (the silver medicine is a soft body formed by the blending of more than 95% of the color of the ** surface and mercury) on the silver channel.

If you put honey on a paper towel, if the honey does not seep easily, it means that it is real honey, but if the honey penetrates quickly, it means that it is inferior honey. On the surface, this is indeed the case, but if you think about it, you can see where the flaws are. Because the concentrated honey droplets are not easy to seep on the paper towel, it can be found that this method only identifies the amount of water content. >>>More
