diamonds Could anyone tell me if the word "diamond" is used only for a faceted jem or whether it's a raw material too?

It definitely is the 'mineral'. It is (as Brian said) an allotrope of carbon (along with graphite ) It is also of course most commonly used as an abrasive - using 'industrial diamonds' - for things like diamond files, glass grinders, and diamond knife sharpeners.

Not that Wikipedia is infallible, but according to their entry on diamond, it seems rather clear that the term also refers to the mineral, and not just to the gemstone: In mineralogy, diamond (from the ancient Greek αδάμας – adámas "unbreakable") is a metastable allotrope of carbon, where the carbon atoms are arranged in a variation of the face-centered cubic crystal structure called a diamond lattice.
