The stamp "928" on jewelry indicates that the piece is made of 92.8% silver, which is higher than the standard sterling silver content of 92.5%. This means the jewelry is of higher purity than typical sterling silver items. The remaining percentage usually consists of other metals, often copper, which helps to enhance durability. Jewelry marked with "928" is generally considered to be of good quality.
