What does the number 935 stamped on stirling silver mean?

The number 935 stamped on sterling silver indicates that the metal is composed of 93.5% pure silver and 6.5% other metals, typically copper. This higher silver content distinguishes it from the more common sterling silver standard of 92.5% purity (925). Items marked with 935 are often of higher quality and may be used in fine jewelry and silverware. The stamp is a hallmark that helps identify the metal's purity.
