In the silver jewelry market, there are two kinds of silver that are most popular and widely used: S999 and S925 silver. But most users can not distinguish them and call them silver in general. We will show the difference between them as following:
First of all, you should know that there is no 100% pure silver jewelry; because silver is a very soft metal, easily be deformed or distorted when hitting so when using to make jewelry, silver is often mixed with other metals to strengthen its solid. The highest level of silver used to make jewelry is 99% and no pure 100% silver jewelry.
S925 silver is 92.5% pure silver mixed with other metals such as: platinum and rhodium. This kind of silver is used most often to make jewelry, especially one with dedicated design because of its solid and shiny beauty.
S999 silver is the type of silver which contains highest silver content with only 0.1% of other metals. So the jewelry made from S999 is comparatively soft, easy to deform or distort and not as solid as S925 silver.
Both two kinds of silver have the ability to avoid evil souls and eliminate poison. When the silver becomes black, it is just because of its reaction with hydrogen sulfide containing substances, such as: sweat, air or hot springs… So all you need to do is polishing it with designated chemical or using simple material like toothpaste, baking soda to clean it.
