952 sterling silver jewelry actually refers to silver products with a silver content of 92.5% (925 thousandths). 925 represents the purity of silver and is the highest purity of silverware, just like 999 gold. Because Ginta is soft and easy to be oxidized by air, adding 7.5% alloy to pure silver can improve the luster, brightness and hardness of silver. Since Tiffany founded 925 Silver, 925 Silver has been internationally recognized as pure silver, recognized by all countries in the world, and is the international standard silver for silver ornaments. Most of the sterling silver ornaments we usually see in the market are 925 silver, not 999 sterling silver. 925 silver is a kind of synthetic silver, which consists of 7.5% alloy and 92.5% silver. It is the newly added 7.5% alloy metal that makes the 925 sterling silver forged jewelry stronger and less prone to wear and deformation, while the real 999 sterling silver is as soft as pure gold, so the jewelry made of alloy sterling silver will be durable and will not be deformed and worn out after a few days.
Many customers ask whether sterling silver will change color. In fact, silver is a very active metal, which easily reacts with sulfur in the air to darken or blacken the color of silverware. This is determined by the nature of silver products, so it is particularly important to pay attention to the daily maintenance of silver jewelry. For example, it is not suitable for wearing in places with strong chemical gases. After touching sulfur soap or soap, it must be dried immediately. It should be noted that chloride in sweat also has a certain influence on the color of silver.
It should be noted that silver and gold are not suitable for wearing at the same time. The contact between silver and gold will cause the color of silver to turn yellow. Of course, due to the characteristics of silver itself, even if it is not worn at the same time, pure silver jewelry will be oxidized and discolored by air whether it is electroplated or not.
Therefore, friends who like to wear silver ornaments must learn how to maintain silver ornaments, such as extending the bright time of silver ornaments and learning to restore the luster and brightness of oxidized silver ornaments. Primary color, surface polishing, very simple, just wipe it with silver cloth several times; If the surface is not polished and cracked, it can be cleaned with special silver washing water; If the surface is treated by electroplating process, it should be wiped with a soft cloth to avoid contact with chemicals (such as bath, soap, chemical reagents, perfume, etc.). ) Because the electroplated layer is very thin, the wiping of woolen cloth and the destruction of chemical substances will affect the luster and brightness of the surface of sterling silver jewelry.
It's not just sterling silver jewelry, in fact, no matter what kind of jewelry it is, MM had better take it off in the shower and store it in a dry place when sleeping. 925 sterling silver jewelry is a kind of metal that is easy to oxidize and discolor, so we should pay more attention to this problem.
