I have a ring made of Tungsten Carbide. It has some scratches on it. How could this have happened?

I don't own or handle any diamonds, and my understanding is that Tungsten carbide is one of the hardest substances around. Is there anything that I may encounter in my every day life that has the ability to scratch my ring?

You have to remember the pressure applied to the ring can overcome the point at which cleavage occurs. You can smash a diamond with a hammer and some force. You can scratch a ring with the right amount of pressure even with an item that is not as hard as the material that the ring is made out of.
