Argentium is one of a new generation of silver alloys. It was developed specifically to combat the tarnish that occurs as silver oxidizes when it comes into contact with air. Argentium is a more expensive and finer quality silver compared to sterling silver due to its unique qualities. Compared to sterling silver, Argentium is stronger, whiter, and easier to weld. It also contains a higher pure silver composition alloyed with germanium, making it seven times more tarnish resistant.
