How to distinguish the authenticity of sterling silver jewelry! As the title suggests, thank you

The commonly used inspection methods are: Look at the color of the jewelry: the higher the purity, the whiter the silver, and the surface of the jewelry looks uniform and shiny, with polish.

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 of jewelry: **The density is slightly larger than that of common metals, generally speaking:

The aluminum is light, the silver is heavy, and the copper is not light and not heavy. 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.

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, 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. Listen to the rhyme:

Sterling silver jewelry is loud and non-elastic, 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. It is also not ideal to examine silver jewelry based solely on its physical properties and experience.

Only by destroying the silver jewelry can the authenticity of the silver jewelry be detected by chemical methods. However, this is something that consumers can't reach. In addition to mastering some basic inspection knowledge when buying silver jewelry, consumers should also pay attention to whether there are relevant certificates, certificates and signatures for silver jewelry.

In addition, the silver content of silver jewelry must be accurately marked, and consumers should check whether there is the word "925" on the jewelry when purchasing. "925" is the symbol of sterling silver. As long as you have "925", you can be sure that you are buying real sterling silver jewelry.

Remember.

Sterling silver items can be used the old way, and a flick of your fingers will make different sounds.

It is best to go to a jewelry store to verify how to distinguish the authenticity of silver jewelry? Now the silver jewelry part of the Internet is not up to standard, are small factory processing, this adulterated 925 silver jewelry is particularly profitable, and the metal used is harmful to the human body, so we should be vigilant against cheap silver jewelry, now teach you some identification methods, if there are conditions, please buy to the local identification agency for identification, so as not to be deceived. 1) Look at the color (also known as look at the noodle file) test:

The higher the purity, the whiter the silver, the delicate, even, shiny, and polished. If it contains lead, the dough is tidal with a blue-gray tinge; If it contains copper, the dough will appear rough and rotten, and there will be a feeling of dryness. Although there is "black rust" on the surface, the oxidized ** is black and bright, lead, tin, and white copper.

It has no luster, and its color is twilight. (2) Weight: **The density is slightly larger than that of common metals, generally speaking:

The aluminum is light, the silver is heavy, and the copper is not light and not heavy. Therefore, a preliminary judgment can be made on whether it is **. If the jewelry is large in size and light in weight, it can be preliminarily judged that the jewelry is other metals.

3) Check the hardness: **The hardness is lower than copper, and larger than lead and tin, so use a pin to scratch the surface of the real object for testing, if the needle is slippery, the surface is difficult to leave traces, it can be judged as 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. Pure ** jewelry is pulled by hand, and it can be deformed by folding.

4) Listen to the sound rhyme: if the jewelry is high quality, there is no rhyme, no elasticity, and the sound is "porphyry". The lower the color, the lower the sound, and the sharper and higher the voice, with 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.

5) Look at the stubble to determine the color: 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 color of the surface after oxidation is black and bright, and it can be concluded that its color is about 98; If the stubble is thick and soft, slightly red, the color is about 95; The stubble is white and grayish, slightly reddish and the color is about 90; It is hard to bend by hand, the stubble is pale red or gray, and its fineness is about 80; The color is about 70, the surface is white and yellow, dry, the stubble is reddish and yellow, and the bending is hard; If the stubble lipstick is black in the middle and black in the yellow, its color is below 60. (6) Characteristics of forgery:

Counterfeiting ** is generally made of red copper.

Made of brass, white copper, lead, tin, aluminum, etc., its characteristics are: red copper: purple red appearance, black red stubble, green embroidery.

Brass: yellow in appearance, green in stubble, green embroidery. Copper:

The appearance is gray-white, the stubble brick is gray, and the green embroidery is raw. Lead: gray-blue, soft, with fingernails can be scratched.

Tin: silvery-white, soft, with nails can be scratched. Aluminum:

White-gray, the constitution is soft and light.

Some silver jewelry has something else added to it, and it's not all sterling silver.

1. Look at the logo.

According to national regulations, the silver content of silver jewelry must be accurately marked, and consumers should check whether there is a mark on the purity of the jewelry S925, AG925 (fashion is more common), or S990, AG990 (traditional bracelet child lock). If it is not marked, it can be concluded that it is a common metal.

2. Look at the color.

The higher the purity of the silver, the whiter the silver bracelet will appear, the color of the face file is delicate and uniform, and there is polish, if it contains lead, the tide of the face file will be blue-gray, such as copper, the face file is rough and rotten, and it will appear relatively dry.

3. Look**.

At present, the Shanghai **Exchange** is about 5 yuan per gram, which does not add procurement costs, process costs, etc., if the **low is outrageous, it must be not pure enough or fake.

4. Weigh the weight.

**The density is slightly larger than that of common metals, gram cubic centimeters, so the weight can be weighed to make a preliminary judgment on whether it is **.

5. Check the hardness.

**The hardness is lower than copper, but the hardness is greater than lead and tin. You can test the surface of the silver bracelet with a little force with a pin, and if the needle will slip and it will be difficult to leave marks on the surface, it can be judged to be a copper jewelry. If it is lead and tin texture, the traces will be obvious and prominent; If there are traces in the object and it is not obvious, it can be preliminarily judged to be ** jewelry.

6. Listen to the sound.

Softer than platinum, throwing it on a hard object, silver bracelets will make a weak sound, while other metals will make a crisp sound.

<>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.

<>1. Look at the color.

Check the authenticity of silver jewelry can see the color, the higher the purity of the silver, the more white, bright and uniform the color will be, the color of the silver jewelry with poor color or other metal imitation will be slightly dull, and the surface of some imitation silver jewelry will give people a rough feeling.

2. Weigh the weight.

In addition, check the authenticity of silver jewelry can also weigh the weight, in addition to platinum, the density of silver is greater than other similar metal density, its density is gram cubic centimeters, so silver jewelry in the bending hand to weigh will have an obvious pendant of the cherry blossom feel, and other materials imitation of the silver pendant feel is not strong.

3. Look at the logo.

China stipulates that all first-class jewelry needs to be marked on the surface to illustrate the purity of silver jewelry, and the common marking of silver jewelry is S999, S silver, etc. If there is no such mark on the surface of the silver jewelry, it may be a fake.
