S stands for the symbol of silver, and 925 refers to the purity of silver. 925 silver usually bears the steel seal of "s925" or "ag925", where "S" is the abbreviation of silver and "ag" is the symbol of chemical elements of silver. Compared with foot silver, 925 pure silver has higher hardness, more stable performance, and is not easy to be deformed and oxidized to black.
925 silver is the international standard silver for silver ornaments, also known as pure silver. In addition to s925 silver, the common specifications of silver jewelry are s990 silver, with a silver content of not less than 99%, also called Zuyin and s999 silver, with a silver content of not less than 99.9%, also called Qianzu silver. Foot silver is soft and easy to be oxidized and deformed, while s925 pure silver is added with 7.5% other metal components, which not only enhances the hardness, but also obtains more stable performance. Long-term wear is not easy to deform and change color, and can be made into various exquisite ornaments.
Matters needing attention
But whether it is foot silver or pure silver, you should pay attention to maintenance and care when wearing it every day. Try not to put it in a dirty environment, and don't let it come into contact with chemicals such as facial cleanser, shower gel and shampoo, otherwise the silver ornaments will turn yellow and black.
The best way to maintain silver jewelry is to wear it every day. Human oil can make it have a natural and moist luster, and the more it passes through, the better it looks. But it is best not to wear it when taking a bath at ordinary times, and take it off and store it in a dry place when sleeping at night.
