What Does 925 Mean on Silver?
The “925” stamp found on silver jewellery or accessories indicates the piece is made from sterling silver—an alloy containing 92.5% pure silver and 7.5% strengthening metals. Because pure silver (99.9%) is too soft for everyday wear, copper is added to enhance durability while preserving silver’s bright, lustrous appearance. The “925” mark is typically stamped inside rings, clasps, or earring posts to confirm authenticity and quality.

The History of Sterling Silver
The term “sterling silver” originated in 12th-century England when silver coins had regulated purity standards. Over time, it came to represent silver alloys made with 92.5% pure silver—a blend that is both strong enough for everyday use and still displays silver’s natural shine. Today, the 925 hallmark continues this legacy, helping buyers identify quality sterling pieces worldwide.

Does 925 silver turn green?

Can you shower with sterling silver?

Does sterling silver tarnish faster in humid climates?
Yes, sterling silver can tarnish more quickly in humid climates because moisture in the air accelerates the natural reaction between copper and sulphur. Storing 925 silver jewellery in a dry place and cleaning it regularly helps minimise tarnish.
