I may be able to answer very general questions in those venues.

Geology - diamond.

Expert: C. Robert Reszka, Jr. - 10/29/2009

Question
please tell the diamond is hardest mineral in moh's hardness scale then what other mineral can cut the diamond.

Answer
Hi Sartaj,
Good question. So far the only substance that we have that will cut a diamond is another diamond. They use diamond dust or grains to polish the surfaces after the diamond has been cleaved to the proper shape.
Here's a pretty good site on diamond cutting:

Hope this helps.
Bob
