What gives the color to tungsten rings?

Our tungsten rings undergo a special process called ION plating which is much more effective than other conventional plating processes. Ion plating is more stable and much harder than other conventional plating processes. Ion plating can handle bumps and abrasive surfaces extremely well. ION platting is also way less likely to ever fade. The only tungsten rings that do not undergo ION plating would be the silver tungsten rings because silver is the natural color of tungsten. Major brands use the same plating process such as Apple, Calaway, and Rolex.
