Understanding 925 and S925 Silver
The terms 925 and S925 both refer to sterling silver. Sterling silver is an alloy made of 92.5% pure silver and 7.5% alloy metals, usually copper. The “925” stamp is a numeric hallmark showing silver purity, while “S925” includes the letter “S,” which stands for “Silver.” Despite the difference in appearance, both stamps represent the same silver standard.
Are 925 and S925 Silver the Same?
Yes, 925 and S925 are essentially identical. The only difference is how jewelers mark their products. Some regions prefer using just “925,” while others add the “S” for clarity. Both stamps guarantee that the piece meets the sterling silver purity requirement of 92.5% silver content. For buyers, this means there is no material difference between the two markings.

How to Identify Genuine Sterling Silver
Regardless of whether a ring or necklace is stamped 925 or S925, buyers should check authenticity through weight, tarnish behavior, and purchase from trusted jewelers. Genuine sterling silver is durable, slightly tarnishes over time, and can be polished back to shine. Counterfeits may use fake hallmarks but will not have the same feel, weight, or long-term quality.
Conclusion
There is no real difference between 925 and S925 silver—both mean sterling silver with the same purity level. The variation lies only in the hallmark style. Whether you choose jewelry marked with 925 or S925, you can be confident you are purchasing authentic sterling silver if it comes from a reputable source.
