The marking ‘S925’ on jewelry indicates that the piece is composed of 92.5% silver. The remaining 7.5% is typically comprised of other metals, usually copper, to enhance the alloy’s durability. This designation is a standard quality mark, commonly found on sterling silver items.
This level of silver purity offers a balance between malleability and strength, making it suitable for intricate designs and everyday wear. The addition of other metals improves the silver’s resistance to scratching and bending, extending the lifespan of the jewelry. Historically, silver alloys have been used to create more durable and affordable alternatives to pure silver while retaining a significant portion of its aesthetic qualities.
