A revolution in silver, Argentium is the number one choice for jewelry designers who value long-lasting shine. Untarnished by time, Argentium silver stays bright and beautiful for years. Due to the presence of a rare metallic element called germanium, Argentium is highly resistant to tarnish. Germanium is a hard element with a metallic luster and the same crystal structure as diamonds. By replacing copper found in regular sterling silver with germanium, Argentium silver offers long-wearing shine that will stay in pristine condition with the occasional rub of a soft cotton cloth.
