The setting and band of this ring are made from argentium sterling silver and fine silver. Argentium sterling silver is a patented type of sterling with more pure silver than regular sterling silver (94% vs. 92.5%). It resists tarnish, finishes hard, and exhibits a bright silver color. It is hypoallergenic and contains no nickel.
