Generally diamonds will crystallize in a tetrahedral structure which is essentially cubic. They will generally form as a crystal and fill in the hole, or space where they formed. This is usually rounded. Rough diamonds are therefore rounded. However since they crystallize with their atoms formed in flat sheets as might be expected if you lay square boxes on top of each other. The layers can be cleaved along cleavage planes, such as between the layer of boxes in the example, leaving very flat surfaces or edges. These edges are polished flat to bring the finished diamond to its final brilliance.

It's the hardest mineral in the world...so obviously only a diamond could cut another diamond...(or maybe some type of laser)

It's crystalline structure. Diamond is carbon with each of its four valence electrons connected to different carbon atoms. It crystallizes in the shape it is in and forms points and edges during crystallization.

Superman once squeezed a lump of coal and turned it into a diamond to impress Lois Lane.

Maybe dumb of me, but is it not because the sharp point is used to cut (other diamonds, etc).

They are cut that way to pick up maximum light.
