If you have spent any amount of time in a machine shop you know that hardness is king. Steel is used to cut aluminum. High speed steel can cut regular steel. But the boss of metals is tungsten carbide. Not only is tungsten hard and heavy, it does not wear out under daily use. A tungsten carbide ring will look just as shiny 10 year later as it did the day you said, "I do": forever.
When selecting a ring, I wanted a two tone ring. Tungsten rings are silver in color. Dark grey tungsten is achieved by a anodizing process. This process only colors the metal a few atoms deep. Though hard, tungsten can still get micro scratches. These small scratches typically do not show up and do not degrade the overall shininess of the metal. However, when a layer of anodized tungsten is scratched off, the silver base metal will show through. This results in a scratched looking surface.
A solution to this two tone anodized problem is to inlay a darker material. A common inlay material for tungsten carbide rings is ceramic. Unlike your office coffee cup, hold on as I take another sip from mine, the ceramic used for rings is a much harder industrial ceramic. This type of ceramic is commonly used in bullet prof vests as a ballistic plate. Some claim that since ceramic is so hard, ones need to be careful with it, so as not to shatter the ring or inlay material. This is false. I have never been gentle with my ring and have not one blemish on it. The ring in the picture above is the one that I wear. It was purchased by my wife at a local jeweler. A basic Tungsten carbide rings can be purchased for under $50. Fancy ones can run up to $300. The low cost of these rings is a welcoming figure in the high dollar world of weddings. After all isn't love free.
So now I wonder: what type of wedding ring did Prince William get?
