The 925 silver mark is the international standard for sterling silver, indicating 92.5% pure silver content and serving as the primary quality indicator.
925 silver means 925 parts per thousand are pure silver, with the remaining 75 parts typically being copper for strength and durability.
The 925 standard is recognized worldwide, though different countries may use additional symbols or marks alongside the 925 number.
Properly marked 925 silver guarantees minimum quality standards and legal compliance in most silver-selling jurisdictions.
