No. Talc is the softest mineral. It can't scratch anything that is harder that itself. Talc is number 1 on the Mohs scale, a scale of hardness, but diamond is number 10, which means that diamond is very much the harder of the two. You can't even scratch a diamond with a fingernail, hardness of about 2.5, so talc with even less hardness doesn't stand a chance against the mighty diamond! See Related Links below this box for more information about the hardness of talc, diamonds and other materials.

There are four elements that are used to make talc. They are oxygen, hydrogen, silicon, and magnesium. Care should be used when using talc so that you do not inhale the dust from it.
