Preventing the discoloration of sterling silver, a metal alloy comprised of silver and other metals (typically copper), involves minimizing its exposure to elements that cause it to darken. This darkening, known as tarnish, is a chemical reaction between the silver and sulfur-containing compounds in the air or on surfaces. An example of this is the black residue that forms on silver jewelry after prolonged contact with skin or when stored in a humid environment.
Maintaining the luster of sterling silver extends its lifespan and preserves its aesthetic value. Untarnished silver retains its reflectivity and brilliance, attributes that are often central to its appeal. Historically, preserving silver’s appearance has been significant, reflecting both the value of the material itself and the owner’s commitment to care and maintenance. A well-cared-for piece of sterling silver can last for generations.
