**Argentium silver is a brand of modern tarnish-resistant silver alloys. It contains a slightly higher silver content than traditional sterling silver. It contains either 93.5%, 94% or 96% silver. Argentium alloys replace some of the copper in the traditional sterling silver with the metalloid germanium. This alloy helps reduce tarnish and gives the silver a brighter appearance.
