925 silver generally refers to silver products with a silver content of not less than 92.5%, and the purity above this is regarded as pure silver. Because high-purity silver is soft and easy to be oxidized, 925 silver is added with 7.5% other metals to make it have ideal hardness, which can be better shaped and inlaid with various gems to make various silver products.

925 sterling silver is the international standard silver for silver ornaments. Printed silver ornaments are generally stamped with the English abbreviation of silver. The mark of standard silver is S925. The imprint of foot silver is S990.

Now many silver rings are made of 925 silver, because it is not easy to change color.
