Argentium Silver is a high-karat sterling silver that is purer and whiter than traditional sterling silver, and made exclusively from recycled silver.Argentium Silver contains no nickel, and less copper than traditional sterling.  An element named Germanium is added to the alloy, which gives Argentium its unique tarnish-resistance and fusing properties.Argentium Silver is also hypoallergenic, making it ideal for wearers who have issues coming into contact with other metals.  This makes it an especially excellent option for first-time earrings wearers.All of my Argentium Silver pieces are properly kiln fired and finished for optimal strength and tarnish resistance.
