925 silver jewelry is a common jewelry, due to the variety of styles by women love, follow me to see how to identify whether it is 925 silver.

01 If it's a real 925 silver, draw a line on the wall, and a light gray line will appear on the wall, but fake silver won't.

02 The color of real 925 silver is shiny, and the jewelry is printed with clear marks, the color is irrelevant and the color is dull, and the blue-gray ones are mostly fake 925 silver.

03 Because the fake 925 silver is mixed with other alloy materials, it will change color after staying for a while, and if it is copper gold-plated, it may fade.

04 People with allergies may cause redness, swelling and itchiness if they come into contact with fake 925 silver.

Identification methods. First of all, look at the color. The higher the purity of silver jewelry, the whiter the silver, and the surface looks even shiny and polished. 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.

Secondly, weigh the weight. **The density is slightly larger than that of common metals, light aluminum, heavy silver, and copper is not light and 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.

Again, 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.

Finally, 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.

In addition, the silver content of silver jewellery must be accurately marked, and consumers should check whether there is the word "S925" or "925" on the jewellery when purchasing. "S" is the first letter of the English word for silver, and "925" is the symbol of sterling silver. As long as you have "S925", you can be sure that you are buying real sterling silver jewelry.

When purchasing, pay special attention to whether its fasteners can be fastened and secure. When buying a silver chain, lay it flat to see if the chain links are kinked or bent. (Here 925 refers to the content of standard silver, as well as the content of alloy, because the physical characteristics of sterling silver are not suitable for jewelry, sterling silver is basically not used to make jewelry, jewelry generally uses electroplating methods, jewelry can be preserved for a long time).

Nowadays, people are more and more fond of gold and silver jewellery and are accustomed to using it to dress themselves, especially in more formal occasions.

Identification method of 925 sterling silver

Imprints

In general, 925 sterling silver jewelry is stamped with the English abbreviation (S or sterling) of silver. For example, the mark of standard silver is S925, while the mark of pure silver is S990. However, there are also many countries that do not print on silver jewelry.

Everyone should pay more attention when judging, although this method is not particularly effective, but it is still helpful.

Color

Silver jewelry is generally a silvery-white with a slight yellowish tinge, and has a soft color. Metallic luster. Because silver is easily oxidized, the color of silver jewelry will change to a dark yellowish-white color after a long time. It works, but it takes a while to see it.

Heavyweight

We know that silver has a density of grams per cubic centimeter, which is less dense than platinum and **. Therefore, when we use our hands to lift them, we do not feel like we are falling. And when we prick it with a steel needle, we can scratch out the marks of the silver jewelry, and we can also bend it.

So we can use this method to distinguish 925 sterling silver from platinum, karat platinum, or imitation silver jewelry.

Acid test

Silver will change color when it encounters any acid, and some will dissolve it. According to this principle, we can drop a drop of concentrated hydrochloric acid on the inside of the silver jewelry, and if a white moss-like silver chloride precipitate is immediately generated, it means 925 sterling silver. This is not the case with other *** jewelry.

Phonology

In general, the sound of standard silver jewelry is muffled after it lands, it neither bounces nor rolls. This is not the case with jewelry made of other metals. They make loud noises while also rolling or bouncing at a certain speed.

Plating

We can take silver jewelry for plating, and if its appearance changes a lot, it means that it is 925 sterling silver. On the contrary, if there is not much change after electroplating, then it is jewelry of other metals such as cuss and brass. At this time, we can also use some tools to break the electroplating layer on the surface to see if the color of the material inside is silvery-white, if it is 925 sterling silver, otherwise it is jewelry of other metals.

When you buy silver jewelry, you must carefully identify it according to this method to avoid buying fakes.
