This 5mm Stainless Wedding Band is constructed from 304L Stainless Steel. It is plated in a 18k gold color using a process called IPG (Ionic Plating Gold). If you have a 14k 18k or 22k gold wedding band that is showing scratches replace it with one of these for the same look. 18k plated gold is achieved using an electroplating process that coats the item with heavy layers of 18k Yellow Gold and color-treated to display a perfect 14k Hamilton gold color.
