About 925 Sterling Silver Jewelry Silver is 925 sterling silver. Sterling silver is too soft for everyday objects, so to increase the hardness of silverware, about 7.5% copper is usually added. 925 sterling silver does not contain nickel, so it is an inactive metal. This means that it does not (usually) evoke a reaction when it comes into contact with the skin. Sterling silver is comfortable to wear, especially for people with sensitive skin. Care instructions * If you don't want to wear it for a long time, please put it in a sealed bag or box to avoid oxidation. 100% Scrub the silver finish with a silver polishing cloth to remove tarnish and dullness and keep your sterling silver gift looking like new. * Do not wear it together with other metal jewelry and store it separately to avoid collision deformation or wear.
