Small knowledge of silver jewelry

925 pure silver actually refers to silver products with a silver content of 92.5%. 925 represents the purity of silver. This is the minimum standard purity of pure silver, just like the purity of 999 gold. Because Ginta is soft and easy to oxidize, 925 silver has been internationally recognized as pure silver since Tiffany Company was founded.

Silver is an active metal, which easily reacts with sulfur in the air, making silverware black. Therefore, contact with air as little as possible when wearing, and it is not suitable for wearing in places with strong chemical gases. After contact with sulfur soap, it must be dried immediately. Chlorides in sweat can also affect silver.

Silver and gold can't be worn together, which will cause silver to turn yellow. Of course, even if different fashions are used for a long time, silver ornaments will still oxidize and change color, whether or not they are electroplated!

Therefore, friends who love silver ornaments must learn how to maintain pure silver, extend the bright time and learn how to restore the bright color of silver oxide products.

Primary colors, polished surfaces, the simplest. Just wipe it with a silver cloth. If there are cracks in the unpolished surface, it can be cleaned with silver water.

The electroplating surface should be wiped with a soft cloth to avoid contact with chemicals (such as bath liquid, soap liquid, chemical reagents, perfume, etc.). ) Because the electroplated layer is very thin, the wiping of felt cloth and the destruction of chemicals will affect the surface brightness.

No matter what material the jewelry is, it is best for the wearer to take it off and store it in a dry place when taking a shower and sleeping. Pure silver is a kind of metal that changes color easily, and of course it should change color.

Pure silver with primary colors can guarantee no allergy, but platinum plating or other precious metals can't guarantee it.

1. Pure silver: Pure silver is silver with a silver content of 100%. This kind of silver material, due to the characteristics of silver itself, makes 100% silver soft, which is not suitable for the increasingly rich and exaggerated modeling requirements of modern fashion accessories. So it gradually fades out in use. Because 100% silver is easy to identify from the appearance, which is the true color of silver.

According to the national regulations, more than 92.5% of silver can be regarded as pure silver, and the symbol 925 should be marked on silver ornaments. . The reason why other materials should be added to silver is, of course, to make the substrate more plastic and more suitable for ornaments. As for other materials added, there are mainly nickel, copper, rhodium, palladium and so on.

3. 18KGP and 18KGP At present, the jewelry plated with platinum based on copper in the industry is called 18kgp, which used to be called 18kgp, but now it has developed into 18kgp. Any DD with 18KGP will be engraved with the words 18KGP or 18kgp on the jewelry surface. This kind of jewelry has incomparable advantages over other jewelry, that is, it is cheap and brings forth the new very quickly (keeping up with the trend and being fashionable and rich). Of course, inferior 18KGP products abound, with rough electroplating, unsmooth details and poor mosaic technology. Therefore, the price difference of this kind of jewelry is the biggest.

4. Copper: It can increase the hardness and plasticity of silver.

5, nickel: added to jewelry, can make the surface more wear-resistant. But some people, especially white Europeans, are sensitive to nickel, and wearing jewelry containing nickel will make their skin allergic. Pay special attention to this.

3. Throw method: throw the silver jewelry on the table from top to bottom, and the silver jewelry with low rebound and smooth sound is of high quality; High-pitched, shrill voice silver jewelry thrown on the table, which is fake or of low quality.

3. With little knowledge of sterling silver, how to maintain your sterling silver jewelry?

Pure silver is one of the precious metals next to gold at present. Although its price is not as high as platinum or gold, it still far exceeds that of metals such as tin and lead.

Because pure silver is too soft and easily deformed, other alloys are usually added to increase the hardness. Because the alloys added in different countries are different, the international standard pure silver is considered as pure silver as long as its content exceeds 925 ‰. Judgement standard of 925 silver: 925 silver is alloy silver made by adding other metals, and its proportion is 7.5% alloy and 92.5% silver. Jewelry forged with this pure silver is stronger and less prone to wear and deformation, while jewelry made of alloy pure silver will be durable, so that it will not be deformed in a few days and the surface will not be worn too hard.

925 silver is the international standard silver for making silver ornaments. It is different from 9.99 silver, because 9.99 silver is very pure and soft, and it is difficult to make complex and diverse ornaments, while 925 silver can.

In fact, the silver content of 925 silver jewelry is not 100%, because 7.5% alloy is added to pure silver, which improves the luster, brightness and hardness of silver. At present, the silver ornaments on the market are all based on 925 to identify whether they are pure silver.

After polishing, 925 silver jewelry presents a very beautiful metallic luster, but also has a certain hardness, which can be inlaid with gems and made into high-grade jewelry. The silver ornaments designed with 925 silver have European and American styles, which are rough, bold and avant-garde, walking in the forefront of fashion, exquisite and meticulous, and suitable for the tastes of the public.

(5) Look at the color of stubble: cut out the silver ornaments and look at the color of stubble. If the stubble is white and cotton-like, the surface of jewelry is smooth and delicate, and the surface color is dark and bright after oxidation, it can be concluded that its color is about 98%. If the stubble is soft and reddish, the color is about 95%; Stubble is white gray, and if the color is slightly red, it is about 90%; It is difficult to bend by hand, and the stubble is reddish or light gray, and its color is about 80%; Silver with a fineness of about 70% has a white dry surface and red and yellow stubble, which is not easy to bend; If the stubble is red, black and yellow, its color is below 60%.

(6) Characteristics of forged silver: Forged silver is generally made of copper, brass, white copper, lead, tin, aluminum, etc. Its characteristics are: red copper: purple in appearance, dark red in stubble and embroidered green. Brass: yellow in appearance, stubble green and embroidered green.

White copper: appearance gray, stubble brick gray, green embroidery. Lead: grayish blue, soft, with nail marks.

Tin: silvery white, soft, and can be scraped with nails. Aluminum: white gray, soft and light.

But there are also many countries that don't print paper money on silver ornaments. Or 9.25925 marks. There are also thousands of silver labels or S999.

2, check the color

Silver ornaments are mostly yellowish silvery white with a soft metallic luster. Due to easy oxidation, the color will turn dark yellow and white after a long time.

Step 3 consider

The density of silver is10.53g/cm3. Smaller than platinum and gold, it won't fall off by hand. Steel needles can be marked or bent. In this way, it can be distinguished from German platinum, K gold or imitation silver jewelry.

The hardness of silver is lower than that of copper, but higher than that of lead and tin, so it can be tested by marking jewelry in an inconspicuous place with a pin. If the needle slips, it is difficult to leave traces on the surface, which can be judged as copper jewelry; If it is made of lead and tin, the trace is obvious; If the object has traces but is not obvious, it can be preliminarily judged as silver jewelry.
