Argentium Silver is a modern sterling silver alloy which modifies the traditional alloy by replacing some of the copper with the metalloid germanium. Argentium is purer than traditional sterling silver and is low maintenance, easy to care for and simple to clean and is produced using only recycled silver. Here are two links to more about Argentium silver one is very complete and technical about it with a comparison between sterling and Argentium silver... the other from a jeweler who specializes in nickel free jewelry.
