A tungsten carbide ring is pretty spectacular in that it is the only type of ring that will never need to be polished. The polish on the ring can last up to 50 years. This in itself makes a tungsten carbide ring special. A tungsten carbide ring should never dent or scratch; instead you will always have a shiny ring on your finger. You may notice when wearing a tungsten carbide ring that it feels a bit heavier than other types of rings.
